Can Stress Cause PCOS?

Polycystic Ovary Syndrome (PCOS) is becoming increasingly common in women, affecting about one in ten of childbearing age. PCOS often consists of hormonal imbalances, irregular periods, and the development of small cysts on the ovaries. 

While the exact cause of PCOS remains unknown, factors like genetics, insulin resistance, and inflammation are often implicated. 

However, an emerging body of research suggests that stress may also play a significant role in triggering this condition. This raises an important question - can stress cause PCOS?

Understanding PCOS

Before looking at the connection between stress and PCOS, it's essential to understand what PCOS is. Women with this condition often have higher levels of male hormones (androgens), which can lead to symptoms like acne, excessive hair growth (hirsutism), weight gain, and problems with ovulation.

PCOS may also increase your risk for other health complications such as diabetes, heart disease, mood disorders, and infertility. Despite its prevalence and potential severity, many women remain undiagnosed because of a lack of awareness around PCOS or a lack of understanding about this syndrome.

The Stress-PCOS Connection


Stress is a part of everyday life; however, chronic or ongoing stress can have detrimental effects on our health. It can lead to conditions like heart disease, high blood pressure, and mental health disorders. But can stress cause PCOS?


Research indicates that there might be a link between chronic stress and hormonal imbalances associated with PCOS. 


When you're stressed, your body produces more cortisol – also known as the 'stress hormone.' High levels of cortisol can disrupt other hormones in our body, including insulin – leading to insulin resistance – a common feature in women with PCOS.


Moreover, chronic stress may also influence weight gain – another significant risk factor for developing PCOS. Stress triggers cravings for unhealthy, high-calorie foods, leading to weight gain and further exacerbating hormonal imbalances.

The Role of Adrenal Glands on Stress and PCOS

Your adrenal glands are located on top of each kidney. They play a crucial role in your body's response to stress. They produce hormones like cortisol and adrenaline, which help us deal with stressful situations. 

However, in some cases, these glands may overproduce male hormones – a condition known as adrenal hyperplasia.

Adrenal hyperplasia can mimic many symptoms of PCOS, including irregular periods and excessive hair growth. This has led some researchers to suggest that chronic stress-induced adrenal hyperplasia could be misdiagnosed as PCOS. 

Therefore, it's crucial to consider stress levels and adrenal health when diagnosing and treating PCOS.

Managing Stress for PCOS Relief

While it's clear that stress can exacerbate the symptoms of PCOS, it's important to note that managing stress alone may not completely cure the condition. 

However, incorporating stress management techniques into your lifestyle can significantly improve your overall health and potentially alleviate some symptoms of PCOS.

Here are a few strategies:

  1. Regular Exercise: Physical activity is known to reduce cortisol levels and improve insulin sensitivity – both beneficial for women with PCOS.

  2. Mindfulness Practices: Techniques like yoga, meditation, or deep-breathing exercises can help manage stress levels effectively.

  3. Balanced Diet: A diet rich in whole foods and low in processed foods can regulate blood sugar levels and prevent weight gain – key factors in managing PCOS.

  4. Adequate Sleep: Lack of sleep can increase cortisol levels and disrupt hormonal balance. Ensuring you get enough rest is crucial for managing both stress and PCOS.


The Effects of Chronic Stress on PCOS

So, can stress cause PCOS? While more research is needed to answer this question definitively, current evidence suggests that chronic stress may indeed contribute to the development or exacerbation of this condition by disrupting hormonal balance and promoting weight gain. 

Because of these connections, managing stress should be an integral part of any PCOS treatment plan. If you suspect that you have PCOS or are struggling with chronic stress, check out my PCOS Remedy Boot Camp.
