Constipation or Diarrhea
Hormones can have a major impact on bowel movements. The effects of estrogen on constipation are two-fold. First, estrogen slows down the movement of food through the digestive system. This slowing effect can lead to hard stools that are difficult to pass. Second, estrogen causes an increase in blood flow to the pelvic area. This increase in blood flow can lead to bloating and gas, further contributing to constipation.
Another hormone, progesterone, can cause diarrhea in some people and constipation in others. Progesterone is responsible for the growth and thickening of the uterine walls, and it peaks right before ovulation. Progesterone has a relaxing effect on smooth muscles throughout your body, including those in your digestive system. This relaxation effect can lead to slowed digestion and constipation. In some cases, progesterone can also cause diarrhea by increasing muscle contractions in the intestines. Hormones are just one of many factors that can affect bowel movements. Understanding the role that hormones play can help manage bowel issues.
