Nerve Damage
Damaged nerves may hinder the transmission of signals from the brain to the colon, resulting in fewer bowel movements. [7] The sacral nerve is what stimulates urinating and defecation, so damage to this nerve often leads to constipation. It may also cause embarrassing situations where the person experiences fecal leakage because the rectum has gotten too full.
Hormonal Imbalance
Hormonal fluctuations or imbalance may trigger constipation. Pregnancy can cause a spike in progesterone levels, which lead to bloating and constipation. [8] Some women also called experience this condition during ovulation or the monthly menstrual cycle. Sudden hormone changes may slow the function of the digestive system, which leaves you feeling constipated and blocked as a result. Studies have shown that another female hormone called estrogen may lead to constipation.
