3 Ways Cortisol Impacts Women's Hormonal Balance

[INTRO: 0:00–0:20]

Have you ever felt like your body’s working against you? You’re eating right, trying to sleep, and resting well. But your mood’s off, your menstrual cycle is inconsistent, and your energy is running short.

Well... meet cortisol: your body’s main stress hormone. It’s helpful in small doses, but when it's elevated? It can seriously disrupt your hormonal balance, and cause several issues.

Today, let’s talk about 3 ways cortisol affects women’s hormones, and what that really means for your body. But before we continue, hit the subscribe button below and turn on notifications.

1. Cortisol Disrupts Reproductive Hormones:

First off, cortisol and your reproductive system don’t work well together. A study published in the American Journal of Obstetrics & Gynecology found that women with higher stress levels experienced a 30% increase in menstrual irregularities.

When the cortisol level spikes, your brain pauses all the body's reproductive functions (like ovulation). This suppresses the release of gonadotropin-releasing hormone (GnRH), which then affects estrogen, progesterone, and luteinizing hormone.

The result? Irregular periods, missed cycles, and difficulty conceiving.

2. Cortisol Affects Thyroid Function:

If you still feel tired no matter how much you rest, that may be cortisol affecting your thyroid levels. Chronic stress, caused by high cortisol, can slow down the conversion of thyroid hormones (T4 into the active form, T3).

When T3 is low, it causes slow metabolism, low energy, mood swings, and even weight gain. Research from the Endocrine Society has linked prolonged cortisol elevation with decreased T3 levels and disrupted thyroid activity, especially in women. So, your test results may be normal, but you'll still feel weak and tired.

3. Cortisol Contributes to Estrogen Dominance:

High cortisol levels compete with progesterone, a hormone that balances out estrogen. So when cortisol is constantly high, it disrupts the production pathway of progesterone. This creates an imbalance, which is linked to heavy periods, bloating, fibroids, mood changes, and more.

A 2020 review in the Journal of Integrative Medicine confirmed that women with chronic stress had a significantly higher incidence of symptoms related to hormonal imbalance.

So what does this mean? Cortisol isn’t bad, it’s a hormone that signals that there is stress. But when it gets too high, it drowns out the balance your hormones are trying to create. 

If you're struggling with irregular periods, fatigue, or mood swings, it might be time to look beyond your diet or workout. Check your cortisol levels instead.
