For more sensitive and weaker women, pain in the abdomen usually indicates the onset of menstruation. The fluctuation of estrogen and progesterone in women’s body is relatively large before and after menstruation, and the fluctuation of estrogen will trigger congestion and bruising in the pelvic cavity of the abdomen, resulting in pain in the abdomen. The pain in the abdomen is usually physiological, so it is important to avoid getting cold and avoid excessive consumption of cold food, which can trigger the symptoms of pain in the abdomen. If the pain in the abdomen is not related to menstruation, it is important to consult a doctor to determine the specific cause and foci.
