Abdominal pain during physiological period is related to the contraction of uterine smooth muscle due to changes in hormone levels in the body during physiological period. Many hormone levels in the body will change cyclically with the menstrual cycle, and prostaglandin-like substances will increase to varying degrees during physiological periods, often leading to smooth muscle contraction spasms, and some will affect the smooth muscle of the uterus, leading to the appearance of dysmenorrhea, resulting in pain in the lower abdomen. Some may affect the smooth muscle of the gastrointestinal tract, leading to pain around the umbilicus, or accompanied by nausea, vomiting, and diarrhea. The symptoms of abdominal pain during physiological period should pay attention to keep warm, can be hot compresses on the stomach, but also pay attention to eat less cold food, usually pay attention to exercise. Patients with severe symptoms need to consult a doctor in time.
