Scientists’ curiosity about how gut microbes affect our general health and well-being has grown over the past few years. In our intestines, trillions of microbes do much more than help us digest food. Studies have linked gut bacteria to everything from our immune system and metabolism to our mental health and emotions.
One surprising finding is that the composition of gut bacteria can affect women’s moods. Women who had lower amounts of certain gut bacteria were more likely to report experiencing depression, anxiety, and irritation, according to a study published in the journal Psychosomatic Medicine. In contrast, women with a more diverse range of gut bacteria tended to have better emotional well-being.

The study involved 40 healthy women who provided stool samples to analyze their gut bacteria. The participants also completed surveys to assess their mood and emotional state. The researchers found that women with lower levels of bacteria from the genus Lachnospiraceae were more prone to disclose depressive and anxious feelings. These bacteria produce short-chain fatty acids linked to improved mood and brain function.
On the other hand, women with higher levels of bacteria from the genus Ruminococcaceae tended to have better emotional well-being. These bacteria are involved in breaking down complex carbohydrates and producing anti-inflammatory substances.
So Why Might Gut Bacteria Affect Women’s Moods?
According to one idea, the bacteria in our intestines can manufacture and interact with neurotransmitters, which are chemical messengers that help control mood and emotions. For example, certain gut bacteria have been found to produce gamma-aminobutyric acid (GABA), a neurotransmitter that has a calming effect on the brain.

Another possibility is that gut bacteria influence the immune system, affecting the brain and behavior. Researchers have found that changes in the gut microbiome can alter the activity of immune cells called microglia, which are involved in inflammation and brain function.
Although additional study is required to completely comprehend the link between gut bacteria and women’s moods, these findings suggest that caring for our gut health may be essential to promoting emotional well-being. Eating a balanced diet rich in fiber, fermented foods, and prebiotics can help to nourish our gut bacteria. Exercise, stress reduction, and getting enough sleep also benefit gut and mental health.
Women’s moods are linked to gut bacteria, highlighting the value of a holistic approach to health that considers the interplay between the immune system, microbiome, and brain. By nurturing our gut bacteria, we can support our emotional well-being and improve our overall quality of life.
