The Gut-Hormone Connection: Why Digestion Impacts Your Mood and Cycle

Posted in Wellness   |   By Yasmin S.

Your gut is more than just a place to digest food—it’s a major player in hormonal health. From your mood swings to your period symptoms, your digestive system could be influencing more than you realize. Here’s how.

1. The Gut is Home to Estrogen-Regulating Bacteria

Your gut microbiome includes bacteria that help process and eliminate estrogen. When gut health is off, estrogen can build up, leading to issues like PMS, bloating, or irregular cycles. Keeping your gut balanced supports more stable hormone levels.

2. Digestion and the Stress Hormone Connection

The gut and brain communicate constantly through the gut-brain axis. When digestion is impaired—due to stress, inflammation, or poor diet—it can trigger an overproduction of cortisol, the stress hormone. Elevated cortisol can throw off your other hormones like progesterone and estrogen.

3. Nutrient Absorption Affects Hormonal Production

Your body needs nutrients like B vitamins, zinc, and magnesium to make and regulate hormones. If your gut isn’t absorbing nutrients well, your hormone production can suffer. A healthy gut ensures your body gets what it needs to stay in balance.

4. Gut Imbalance Can Trigger Mood Swings

Did you know about 90% of your serotonin (the “feel-good” neurotransmitter) is produced in the gut? An unhealthy gut can lead to mood changes, anxiety, and low energy—especially around your menstrual cycle.
