The judgment of uterine excitation contraction should be based on the cause, which usually occurs in the case of sexual orgasm, pre-miscarriage and signs of labor. 1. Orgasm: During sexual intercourse, rhythmic contraction of anal and vaginal muscles may cause orgasm, resulting in uterine excitation and contraction, which is manifested by localized muscle tension, redness of the skin, and increase in heart rate. 2. Pre-eclampsia: For women in the early stages of pregnancy, the uterus may be stimulated by external factors, thus triggering irregular contractions, mainly caused by uterine excitement, accompanied by vaginal bleeding and abdominal pain and other symptoms. 3. Symptoms of labor: When a woman is approaching her due date in late pregnancy, she may experience contractions caused by uterine excitement, and as the labor progresses, the contractions will gradually become more regular, and there will also be water breakage and redness in the vagina. It is recommended that the patient should determine whether the contractions are contractions of uterine excitement according to their own situation, and then give appropriate treatment.
