What Causes Postpartum Depression? Copper, Zinc, Hormones & the Walsh Approach
Postpartum depression is usually explained by hormonal withdrawal, lack of sleep, stress, genetics, or previous depression. All of those can matter. But they do not fully explain one of the most recognizable postpartum patterns: depression accompanied by severe anxiety, panic, agitation, irritability, racing thoughts, sensory sensitivity, and an inability to sleep even when exhausted.
The Walsh Approach places particular emphasis on copper overload and low zinc in this picture. Pregnancy is naturally a high-copper state because copper is required for the placenta and developing baby. After delivery, copper should begin returning toward the non-pregnant range. In many women seen in Walsh-oriented practice, that transition does not occur efficiently enough. Some entered pregnancy with elevated copper or inadequate zinc already; others have hormonal, metabolic, environmental, or biochemical factors that make copper harder to regulate.
Copper also has a direct connection to brain chemistry. Dopamine beta-hydroxylase is a copper-dependent enzyme that converts dopamine into norepinephrine. Norepinephrine is one of the body's major alerting and fight-or-flight neurotransmitters. This helps explain why copper overload can present not merely as sadness, but as an activated postpartum syndrome dominated by anxiety, agitation, panic, irritability, and insomnia.
The central idea is simple: pregnancy is supposed to raise copper. After delivery, copper is supposed to come back down. The problem develops when a woman enters pregnancy already vulnerable, zinc is inadequate, or copper regulation does not return efficiently to the non-pregnant state.
What Causes Postpartum Depression?
Postpartum depression is not one biochemical disorder. Hormonal withdrawal, severe sleep disruption, previous psychiatric illness, thyroid abnormalities, inflammation, nutritional depletion, medications, psychological stress, and genetics can all contribute.
But the Walsh Approach draws attention to a particularly common pattern: high copper combined with inadequate zinc and an activated nervous system.
A Major Physiologic Shift
Estrogen and progesterone rise dramatically during pregnancy and change rapidly after childbirth. Estrogen also directly affects ceruloplasmin and circulating copper.
Pregnancy Raises Copper
Copper is intentionally increased because it is required for placental growth, fetal development, mitochondrial enzymes, connective tissue, and neurotransmitter biology.
Zinc Must Keep Up
Zinc is equally important during pregnancy. Low zinc weakens copper regulation, metallothionein activity, antioxidant protection, immune function, and fetal growth pathways.
Why Pregnancy Needs So Much Copper
Copper is sometimes discussed only as something that becomes excessive. That misses why levels rise in the first place.
Pregnancy requires copper for:
- Placental blood-vessel formation
- Fetal brain and nervous-system development
- Connective tissue and collagen
- Iron transport and utilization
- Mitochondrial energy production
- Antioxidant enzymes
- Catecholamine and neurotransmitter metabolism
Rising estrogen also stimulates the liver to produce more ceruloplasmin, the major copper-carrying protein in blood. Copper therefore rises progressively as pregnancy advances.
High copper during pregnancy is expected physiology. The goal is not to force a pregnant woman's copper into a non-pregnant range. The important questions are whether zinc is adequate, whether copper was already excessive before conception, and whether copper normalizes appropriately afterward.
Actual Copper Levels Before, During and After Pregnancy
A longitudinal study measured copper in the same women before pregnancy, during each trimester, and five weeks after childbirth. Mean serum copper rose from 0.91 mg/L before pregnancy to 1.48, 1.91, and 2.20 mg/L through the first, second, and third trimesters. Five weeks postpartum it had fallen to 1.09 mg/L. :contentReference[oaicite:0]{index=0}
This graph uses published mean values rather than an illustrative curve.
What Should Happen After Delivery?
Once pregnancy ends, the physiologic situation changes quickly. The placenta is gone, estrogen falls, and the extraordinary pregnancy-related demand for circulating copper decreases.
Healthy postpartum data show this decline clearly. One study found mean maternal copper falling from approximately 218 mcg/dL at delivery to 142 mcg/dL by 12 weeks postpartum, with normal adult copper levels attained within about three months. :contentReference[oaicite:1]{index=1}
Pregnancy builds the copper load. Postpartum recovery requires the body to dismantle it.
What If Copper Does Not Come Down Normally?
This is where the Walsh model becomes clinically useful.
Two women may reach high copper levels during the third trimester for completely normal reasons. But they may enter pregnancy from different baselines and have very different abilities to normalize copper after delivery.
The orange line illustrates the clinically important concept: a woman who begins pregnancy with higher copper or poor copper-zinc regulation has farther to come back after childbirth.
Why Are Some Women More Prone to Copper Overload?
Pregnancy often reveals or magnifies a vulnerability that was already present. That is why a good postpartum history should look backward—not only at what happened after delivery.
Estrogen Dominance & Long-Term Estrogen Exposure
Estrogen increases ceruloplasmin and circulating copper. Long-term exposure to estrogen-containing contraceptives or estrogen therapy can therefore create a higher-copper biochemical starting point.
A meta-analysis of 26 studies found that combined oral contraceptives increased serum or plasma copper by an average of about 0.57 mg/L, commonly producing concentrations between 1.5 and 2.0 mg/L. :contentReference[oaicite:2]{index=2}
Clinically, a history of anxiety, agitation, insomnia, or mood deterioration with birth-control pills, pregnancy, or other estrogen exposure deserves attention.
Obesity & Metabolic Inflammation
Obesity is another important clue. A meta-analysis found significantly higher serum copper in obese adults and children compared with normal-weight controls. :contentReference[oaicite:3]{index=3}
Obesity also commonly brings increased inflammatory and oxidative stress. That combination can create a more difficult environment for copper regulation before pregnancy begins.
Low Zinc
Low zinc is not secondary to the copper story. It is one of its central components.
Zinc helps induce metallothionein in the intestinal wall. Metallothionein binds copper and helps regulate how much copper enters the circulation. When zinc is inadequate, this natural copper-control mechanism is weaker.
During pregnancy, zinc is also essential for DNA synthesis, fetal growth, immune function, antioxidant defense, and cell development. Significant maternal zinc deficiency is therefore undesirable in its own right.
A high-copper/low-zinc state is much more informative than looking at high pregnancy copper by itself.
Pyroluria
Pyroluria is especially relevant because it can help explain why zinc remains chronically low.
Within the Walsh model, pyroluria is a biochemical pattern associated with increased need for zinc and vitamin B6, often becoming more apparent during prolonged physical or emotional stress.
Pregnancy is an enormous nutritional and metabolic stress. A woman who begins pregnancy with poor zinc reserves may therefore have more difficulty maintaining the zinc-copper balance as copper rises.
Typical clues include poor stress tolerance, anxiety, emotional reactivity, low zinc, copper imbalance, poor dream recall, and several characteristic physical findings. When the pattern fits, urinary pyrroles can provide additional information.
Environmental Copper Can Matter Too
Well Water and Copper Pipes
Copper can enter drinking water through corrosion of household plumbing. Water chemistry matters: acidic or corrosive water can increase copper leaching.
Water that remains sitting in copper pipes can accumulate more copper, and hot water is generally more effective at extracting metals from plumbing than cold water.
When copper remains unexpectedly high, the home water supply may be worth testing—particularly with private wells, older copper plumbing, or known corrosive water.
Other Metals Increase the Burden
Copper does not exist in a biochemical vacuum. Zinc, copper, cadmium, lead, mercury, and other metals interact with overlapping metal-binding, antioxidant, and detoxification systems.
Metallothioneins are particularly important. These cysteine-rich proteins participate in zinc and copper homeostasis and also bind toxic metals.
A significant toxic-metal burden can therefore place additional demand on systems that are already helping manage copper.
Metallothionein: Why Zinc and Heavy Metals Matter to Copper
The mechanism is easier to understand without a complicated pathway diagram.
Zinc helps support metallothionein. Metallothionein helps regulate copper. Toxic metals also use this metal-binding defense network.
That creates several ways copper regulation can become more difficult:
- Low zinc: less nutritional support for normal copper control
- Higher copper: more copper that must be transported and buffered
- Heavy-metal exposure: additional demand on metal-binding systems
- Oxidative stress: greater cellular consequences when metal regulation is poor
The practical lesson is that persistent copper overload is not always solved by simply reducing dietary copper. Sometimes the more important issue is why the body is having difficulty regulating the copper already present.
Glutathione Is Part of Copper Regulation
Glutathione is usually described as an antioxidant, but it also participates directly in intracellular copper homeostasis.
Research describes glutathione as being involved in copper entry, intracellular buffering, trafficking, and protection from oxidative stress. :contentReference[oaicite:4]{index=4}
Glutathione Helps Buffer Copper
Inside the cell, glutathione participates in controlling copper availability and moving copper safely through cellular pathways.
Glutathione Protects the Cell
The same molecule also provides major antioxidant protection when reactive metals, inflammation, toxins, and mitochondrial stress increase oxidative demand.
A patient with both high copper and poor glutathione status is therefore dealing with two related problems: more metal stress and less capacity to buffer it.
Where Methylation Fits
Methylation and glutathione metabolism are connected through methionine, homocysteine, and the transsulfuration pathway. Homocysteine can be directed toward cysteine and ultimately glutathione production.
In Walsh-oriented practice, poor methylation-related pathway function can therefore contribute to a broader picture of low antioxidant reserve, toxic burden, and difficulty managing metabolic stress.
This does not mean that undermethylation automatically causes copper overload. It means that when copper remains difficult to correct, glutathione is poor, or environmental burden is high, methylation and transsulfuration can help explain why recovery is incomplete.
Total Copper Is Not the Whole Story
Serum copper is useful, but it should not be interpreted by itself.
Total Circulating Copper
Shows how much copper is measured in serum.
The Major Copper Carrier
Provides essential context for understanding how much of that copper is associated with its principal transport protein.
The Walsh Calculation
Calculated non-ceruloplasmin copper—often called “free copper” in Walsh practice—helps identify copper that is disproportionately high relative to ceruloplasmin.
That distinction matters because pregnancy normally raises both ceruloplasmin and copper. A postpartum copper value that remains high relative to its carrier protein is a different biochemical picture.
Why Copper Overload Often Feels Like Anxiety, Not Just Depression
This is one of the most useful clinical points in the entire Walsh model.
Dopamine beta-hydroxylase is a copper-dependent enzyme. It converts dopamine into norepinephrine—the neurotransmitter involved in alertness, arousal, vigilance, and sympathetic nervous-system activity. :contentReference[oaicite:5]{index=5}
Copper homeostasis therefore intersects directly with the noradrenergic system. Reviews of copper biology describe dopamine beta-hydroxylase as the only copper-requiring enzyme in the catecholamine synthesis pathway and show that copper imbalance can alter dopamine/norepinephrine balance. :contentReference[oaicite:6]{index=6}
This helps explain why the classic copper-overload presentation often includes:
Sudden Anxiety
Episodes of intense fear, dread, internal tension, or feeling that something terrible is about to happen.
Racing Thoughts
The brain feels unable to turn itself off, even when the body is exhausted.
Severe Insomnia
Difficulty falling asleep, remaining asleep, or sleeping despite having an opportunity to rest.
Agitation & Irritability
Anger, sensory intolerance, emotional reactivity, restlessness, and a short fuse can coexist with depression.
This activated presentation is very different from the stereotype of postpartum depression as quiet sadness and fatigue.
What Did Walsh and Crayton Actually Find?
The connection between copper and postpartum depression is not based only on clinical observation.
Women With a History of Postpartum Depression Had Higher Copper
131
mcg/dL
Women with a history of postpartum depression
111
mcg/dL
Women without a PPD history
106
mcg/dL
Non-depressed controls
Crayton and Walsh found significantly higher serum copper in 78 women with a history of postpartum depression. The copper/zinc ratio was also significantly higher because of the copper difference. :contentReference[oaicite:7]{index=7}
How Walsh-Oriented Physicians Think About Prevention
Women with previous postpartum depression, strong estrogen sensitivity, known copper overload, repeated low zinc, pyroluria, or a strong family pattern should not have to wait until another postpartum crisis to investigate these factors.
The approach changes depending on whether the patient is before pregnancy, pregnant, or postpartum.
Before Pregnancy: Correct the Starting Point
This is the ideal time to identify modifiable risk factors.
Establish Copper and Zinc Status
Check serum copper, ceruloplasmin, and plasma zinc. Correct significant zinc deficiency and determine whether a high-copper pattern is already present.
Look for the Reason
Review estrogen exposure, oral contraceptive history, prior pregnancy reactions, pyroluria, obesity, environmental copper, water source, toxic metals, and previous supplement use.
Improve Antioxidant Reserve
When the history suggests poor glutathione, mitochondrial stress, inflammation, or environmental burden, address those problems before pregnancy rather than waiting for pregnancy to amplify them.
Plan Rather Than React
If there is a history of severe postpartum illness, medication strategy and biochemical prevention can be discussed before conception instead of making multiple decisions during an acute postpartum episode.
During Pregnancy: Do Not Treat Normal Pregnancy Copper as Toxicity
This is where copper management requires judgment.
During pregnancy the goal is balance, not aggressive copper removal. The mother and developing baby require copper—and they require zinc.
In a vulnerable patient, a Walsh-oriented physician is generally more concerned with:
- Preventing significant zinc deficiency
- Avoiding unnecessary additional copper supplementation when copper is already ample
- Maintaining adequate nutrition and protein
- Supporting antioxidant status
- Reducing avoidable environmental copper or toxic-metal exposure
- Following symptoms and relevant laboratory trends
- Preparing a postpartum monitoring plan before delivery
Low zinc during pregnancy deserves attention. Zinc is required for fetal cell division, growth, gene expression, immune function, and antioxidant defense. Severe zinc deficiency during embryonic and fetal development can disrupt normal development. :contentReference[oaicite:8]{index=8}
The objective is therefore not “low copper.” It is adequate copper + adequate zinc + efficient copper regulation.
After Delivery: Now Copper Should Begin Falling
The postpartum strategy changes because pregnancy's extraordinary copper requirement has ended.
A patient with previous PPD or a known copper pattern should be watched for the early appearance of:
- Increasing anxiety
- Panic
- Racing thoughts
- Internal agitation
- Irritability or anger
- Sensory overload
- Insomnia despite exhaustion
- Rapid emotional deterioration
These symptoms can justify checking copper, ceruloplasmin, and zinc early rather than waiting months for the problem to become entrenched.
How Copper Overload Is Treated After Pregnancy
The Walsh approach generally aims to restore copper-zinc balance gradually while correcting the factors that allowed the imbalance to persist.
Confirm the Pattern
Measure copper, ceruloplasmin, and plasma zinc rather than treating symptoms as proof of copper overload.
Correct Zinc When Low
Zinc is commonly central to the protocol because it supports metallothionein and reduces intestinal copper absorption. The amount and pace should reflect the actual laboratory pattern.
Support Antioxidant Capacity
B6, glutathione-related nutrients, antioxidant support, adequate protein, and other nutrients may be considered according to the biochemical picture rather than added indiscriminately.
Remove Ongoing Drivers
Address unnecessary estrogen exposure, contaminated water, excessive copper exposure, toxic metals, inflammation, poor diet, and other factors that may be maintaining the pattern.
Retest
Copper treatment should produce measurable movement. Repeat copper, ceruloplasmin, and zinc to confirm that the biochemical pattern is actually improving.
Why Psychiatric Medications Can Complicate the Picture
Medication can be important—and in severe postpartum illness, rapid psychiatric stabilization may be essential.
The problem occurs when medication becomes the only explanation and the only intervention.
With several medications started or changed over a short period, it can become difficult to tell apart:
- The original postpartum illness
- Norepinephrine-driven anxiety or agitation
- Medication activation
- Sedation
- Withdrawal or rebound symptoms
- Persistent insomnia
- Hormonal symptoms
- An unresolved copper-zinc imbalance
A medication can reduce panic, agitation, depression, or insomnia without correcting high copper, low zinc, poor glutathione, or another biochemical driver. These problems can be addressed in parallel rather than forcing an either/or choice.
Which Test Answers Which Question?
Not every patient needs every test. A useful evaluation starts with the clinical question.
Copper Overload Testing
Best starting point when: postpartum depression includes anxiety, panic, severe insomnia, estrogen sensitivity, previously high copper, or low zinc.
Core information: serum copper, ceruloplasmin, and plasma zinc.
Urinary Pyrrole Testing
Consider when: low zinc repeatedly returns, anxiety and poor stress tolerance are longstanding, B6 need appears high, or the physical and behavioral pyroluria pattern is present.
Hair Toxic & Essential Elements
Consider when: well water, plumbing, occupational exposure, mercury, lead, cadmium, arsenic, or broader metal burden may be adding to the copper problem.
Advanced Mitochondrial & Oxidative Stress Panel
Consider when: copper overload occurs with fatigue, poor resilience, significant inflammation, environmental burden, or concern about oxidative injury.
Genova Plasma Methylation Panel
Consider when: poor glutathione, toxic burden, homocysteine abnormalities, suspected undermethylation, or persistent failure to normalize copper suggests a larger pathway problem.
The Walsh Approach
Consider when: copper may overlap with pyroluria, methylation imbalance, oxidative stress, toxic burden, or another biochemical pattern rather than existing by itself.
What About the Baby?
Maternal copper and infant copper biology are connected, although the placenta actively regulates transfer and fetal copper concentrations are not simply the same as maternal concentrations.
Copper is required for fetal brain development, mitochondrial enzymes, connective tissue, iron metabolism, and antioxidant defense. Newborn copper metabolism also continues to mature after birth.
This makes maternal mineral balance important for more than the mother's postpartum symptoms.
Could Copper-Handling Vulnerability Be Inherited?
We know from well-established genetic diseases that copper transport matters profoundly to the nervous system. ATP7A and ATP7B are major copper-transport proteins, and severe abnormalities produce Menkes disease and Wilson disease.
These rare disorders do not mean that common postpartum copper overload is the same disease. They demonstrate something more basic: our ability to transport, distribute, and eliminate copper is genetically controlled.
More subtle differences in copper handling are therefore biologically plausible and remain an important area of study.
What Happens When Copper and Oxidative Stress Occur Together?
Copper is a redox-active metal. That property is essential to many enzymes, but copper must remain tightly controlled.
An infant or child with less-efficient copper handling could potentially be more vulnerable when additional oxidative stress is high.
Examples include:
- Severe or recurrent infection
- Tobacco smoke
- Air pollution
- Poor nutrition
- Low zinc or inadequate antioxidant nutrients
- Environmental toxic-metal exposure
- Highly processed diets as the child grows
- Chronic sleep disruption
The useful concept is not “one exposure causes one disease.” It is the interaction between genetics, copper regulation, zinc, metallothionein, glutathione, mitochondria, and oxidative burden.
A Practical Prevention Strategy for a Woman With Previous PPD
Know the Baseline
Check copper, ceruloplasmin, and zinc. Investigate repeatedly low zinc, estrogen sensitivity, environmental copper, pyroluria, and significant toxic burden.
Preserve Balance
Allow the physiologic copper rise while preventing significant zinc deficiency, maintaining good nutrition, and minimizing avoidable external metal exposure.
Do Not Wait for a Crisis
Watch closely for insomnia, panic, agitation, and racing thoughts. Recheck copper, ceruloplasmin, and zinc early when the clinical pattern begins to recur.
The Walsh Approach Is About Finding the Driver
A diagnosis of postpartum depression describes what is happening. It does not necessarily tell us why.
For one woman, the dominant issue may be hormonal sensitivity. For another, it may be copper overload with low zinc. Another may have pyroluria, thyroid disease, severe sleep loss, toxic burden, methylation problems, or several factors occurring together.
The Walsh Approach is useful because it asks the next question:
What measurable biochemical pattern is creating or sustaining these symptoms—and is treatment actually correcting it?
Frequently Asked Questions
What causes postpartum depression?
Postpartum depression can involve hormonal changes, severe sleep disruption, genetics, thyroid function, prior psychiatric vulnerability, inflammation, nutritional deficiencies, medications, and psychosocial stress. The Walsh Approach places particular emphasis on copper overload and low zinc when depression occurs with anxiety, panic, agitation, irritability, racing thoughts, and severe insomnia.
Why does copper rise during pregnancy?
Copper is needed for placental blood-vessel formation, fetal nervous-system development, connective tissue, mitochondrial enzymes, iron metabolism, antioxidant defense, and neurotransmitter pathways. Estrogen also increases ceruloplasmin and circulating copper.
How much can copper rise during pregnancy?
In one longitudinal study, mean serum copper rose from 0.91 mg/L before pregnancy to 2.20 mg/L in the third trimester—more than twice the pre-pregnancy level.
What should happen to copper after childbirth?
It should progressively return toward the non-pregnant range. Healthy postpartum studies show a substantial decline during the first several weeks and months after delivery.
Why is low zinc important?
Zinc supports fetal development, immune and antioxidant function, and metallothionein. Metallothionein helps regulate intestinal copper absorption. Low zinc can therefore make a high-copper state more difficult to control.
What does pyroluria have to do with postpartum copper overload?
In the Walsh model, pyroluria is associated with increased zinc and B6 requirements. When zinc remains chronically low, copper loses an important nutritional counterbalance. Pregnancy can magnify this mineral imbalance because nutritional demand increases substantially.
Can birth-control pills raise copper?
Yes. Combined oral contraceptives commonly increase serum copper. A meta-analysis found an average increase of approximately 0.57 mg/L.
Can obesity be associated with higher copper?
Yes. A meta-analysis found significantly higher serum copper in obese children and adults compared with normal-weight controls.
Can water or copper pipes contribute?
Yes. Copper can leach from household plumbing, particularly when water is acidic or corrosive and when water remains in the pipes for long periods.
Why do heavy metals matter?
Copper, zinc, and several toxic metals interact with overlapping metal-binding and antioxidant systems, including metallothioneins. A broader metal burden can therefore complicate copper regulation.
What does glutathione have to do with copper?
Glutathione participates directly in intracellular copper homeostasis and also protects cells from oxidative stress. Poor glutathione status can therefore reduce the cell's ability to manage copper safely.
What does copper have to do with norepinephrine?
Dopamine beta-hydroxylase is a copper-dependent enzyme that converts dopamine into norepinephrine. This provides a direct biochemical connection between copper homeostasis and the noradrenergic nervous system.
What symptoms fit a high-norepinephrine or adrenergic pattern?
Anxiety, panic, racing thoughts, inner tension, agitation, irritability, heightened arousal, and severe insomnia are common features of an activated adrenergic state and overlap strongly with the classic Walsh copper-overload presentation.
What is free copper?
In Walsh-oriented interpretation, free copper usually refers to calculated non-ceruloplasmin copper—the amount of serum copper not accounted for by estimated ceruloplasmin-bound copper.
How do Walsh-oriented physicians manage copper during pregnancy?
The objective is generally not aggressive copper removal because pregnancy legitimately requires copper. The focus is maintaining adequate zinc and nutrition, avoiding unnecessary copper exposure or supplementation, addressing environmental risks, and preparing to monitor postpartum normalization in vulnerable patients.
What changes after delivery?
Once pregnancy ends, copper should begin declining. A mother with previous postpartum depression or known copper dysregulation can be tested early if anxiety, agitation, panic, or insomnia begin to return.

If postpartum depression presents with severe anxiety, panic, agitation, racing thoughts, or insomnia, copper and zinc deserve more than an afterthought. A simple copper, ceruloplasmin, and plasma zinc assessment can determine whether this common Walsh biochemical pattern is actually present and whether a broader investigation is warranted.
Copper Toxicity and Postpartum Depression (PPD)
Postpartum depression (PPD) is a common mental health disorder that affects many women after childbirth. A major contributing factor is the fact that during pregnancy, copper levels naturally rise in order to facilitate new blood vessel formation to the developing fetus and placenta. However, a number of women who have an impaired copper removal process have lingering elevated levels of copper, well after delivery. This may be due to estrogen dominance, obesity, hormone therapy or possibly a genetic SNP that causes issue with natural copper removal. This, per Dr Walsh's 5 Biotypes of Depression theory, explains why these women are often depressed and anxious, with possible severe consequences.
Copper Metabolism in PPD
Copper is absorbed through the diet and is transported in the bloodstream bound to a protein called ceruloplasmin. Ceruloplasmin plays a crucial role in regulating copper levels in the body and preventing copper toxicity. However, in women with PPD, the activity of ceruloplasmin may be impaired, leading to elevated levels of free copper in the bloodstream. This excess copper can cross the blood-brain barrier and accumulate in the brain, leading to oxidative stress and inflammation, which are known to contribute to the development of PPD.
Estrogen, Obesity and Copper Overload
In addition to the factors mentioned earlier, estrogen levels also play a role in copper overload and the development of PPD. Estrogen dominance, which occurs when estrogen levels are higher than progesterone levels, can lead to copper overload. Estrogen promotes the absorption of copper in the intestine and the release of copper from tissues, including adipose tissue.
Adipose tissue, or body fat, contains copper, and obesity is associated with higher levels of copper in the body. This suggests that women who are overweight or obese may be more susceptible to copper overload and the development of PPD. Furthermore, the use of hormonal contraceptives such as birth control pills and intrauterine devices (IUDs) can also affect copper metabolism. Hormonal contraceptives can increase estrogen levels and promote copper absorption, leading to copper overload.
Genetics and Post Partum Depression
Genetics and PPD: PPD is known to run in families, suggesting a genetic component to its development. Studies have shown that certain gene variants can increase a woman's susceptibility to developing PPD. One of these genes is the MT2A gene, which codes for a protein that helps regulate copper metabolism in the body. Variants in this gene have been associated with increased levels of copper in the body and an increased risk of PPD.
Diet and Copper in Post Partum Depression
Diet can play a significant role in copper toxicity and the development of PPD. Foods that are high in copper, such as liver, shellfish, nuts, and chocolate, should be consumed in moderation. In contrast, foods that are high in zinc, such as meat, eggs, and whole grains, can help to balance copper levels in the body by competing with copper for absorption in the digestive tract. A diet rich in antioxidants, such as fruits and vegetables, can also help to reduce oxidative stress and inflammation in the body.
Diagnosis and Treatment of Copper Overload in Post Partum Depression
By utilizing the diagnostic approach developed by Dr. William Walsh, PhD and his research organization one can identify whether or not copper toxicity is a significant factor. This approach involves testing copper, zinc, and ceruloplasmin levels in the body and using the results to create a customized therapeutic regimen to help correct the imbalances and improve symptoms. Dr David Epstein, D.O. is a Walsh-trained telemedicine healthcare provider utilizing this approach to provide customized treatment to patients suffering from copper overload.
