Why do women experience more abdominal pain? Scientists have solved an age-old puzzle
Scientists have discovered why women suffer abdominal pain more often and more intensely than men. The reason lies in hormones, nerve sensitivity, and the way the brain processes pain signals. These three factors together make women more prone to stomach pain.
1. A major role of hormones (especially estrogen)
Women have higher levels of estrogen.
- Estrogen affects the muscles and movement of the intestines.
- This makes bloating, gas, and cramps more frequent.
- During periods, changes in estrogen and progesterone increase pain sensitivity even more.
2. More sensitive nervous system
Studies show that the nerves in the stomach and intestines of women are more sensitive than in men.
- Even a small disturbance sends stronger pain signals to the brain.
- This is why conditions like IBS, cramps, and chronic abdominal pain are almost twice as common in women.
3. The brain processes pain differently
In women, the brain areas that control pain and stress are more active.
- Small discomforts are perceived as more intense pain.
- Emotional stress, anxiety, or overthinking can immediately trigger abdominal pain — this is the brain–gut connection.
4. Natural biological processes (periods & ovulation)
- During periods, the uterus contracts, causing pain in the abdomen, lower back, and pelvic area.
- During ovulation, many women feel one-sided abdominal pain (called mittelschmerz).
Men don’t experience these processes, so they naturally have fewer abdominal-pain episodes.
5. Slower digestion in women
In many women:
- Food moves more slowly through the digestive system.
- This leads to bloating, gas, and heaviness.
Even mild indigestion can feel more painful due to nerve sensitivity.
6. Stress & mental load make pain worse
Scientists also point out that women often experience:
- More emotional stress
- Workload and multitasking
- Sleep disturbances
These factors strongly affect the stomach and can quickly trigger abdominal discomfort.
Conclusion
Hormones + sensitive nerves + a different brain response make women naturally more sensitive to abdominal pain. Scientists say this understanding will help create better treatments tailored specifically for women.
