You may have observed that women commonly experience severe abdominal pain during menstruation or pregnancy. However, women often experience abdominal pain and cramps even when these conditions are not present. If abdominal pain is a frequent occurrence, is it normal, or is there a deeper underlying cause? For many years, it was a mysterious question for the medical field: why are gastrointestinal pains more prevalent in women? But now, scientists have unveiled the mystery. A new study has revealed a biological reason that contributes to the increased severity of abdominal pain in women.
Research by the South Australian Health and Medical Research Institute and the University of California has identified estrogen as a key factor in severe abdominal pain in women. The study, conducted on mice, revealed that estrogen triggers an 'estrogen-dependent pathway' in the intestines, increasing serotonin production. This heightened serotonin level sensitizes pain-signaling nerves, leading to increased pain perception in women.
The Scientific Process Behind the Pain
Researcher Stuart Brierley explained this process in simple terms. Estrogen activates a specific pathway in the intestines. This increases the secretion of a hormone called 'PYY' in the intestines. This PYY stimulates the surrounding serotonin-producing cells. In such cases, serotonin production increases, and the nerves that carry pain signals to the brain become more sensitive.
The Influence of Digestion and Gut Bacteria
Another important aspect has emerged from this study. When the bacteria in our gut digest food, they produce 'short-chain fatty acids'. Due to the presence of estrogen, women's intestines react more intensely to these acids, which increases the perception of pain.

This study is considered very important for the medical world because, until now, the exact cause of gut-related pain found in women was not clearly understood. This research has paved the way for developing more effective and targeted treatments for women in the future.
