The main symptoms of gastrointestinal dysfunction during menopause include abdominal distension and pain, nausea, vomiting, and irregular bowel movements. After the symptoms of functional disorders of the gastrointestinal tissues occur, food stays in the gastrointestinal tract for a longer period of time due to reduced operational efficiency, and metabolic reactions occur with the overgrown harmful flora, and a large amount of gaseous substances such as carbon dioxide and ammonia are produced. After forced dilatation of the superficial mucosa of the gastrointestinal cavity occurs, it causes patients to exhibit symptoms such as abdominal distention and pain. Some of the substances in the gastrointestinal cavity will regurgitate to the chest and esophagus with the emptying reaction, thus causing symptoms such as reflex nausea and vomiting. Due to peristaltic dysfunction, metabolites in the body cannot reach the lower gastrointestinal tract tissues such as the sigmoid colon and large intestine quickly and smoothly, so patients with this condition will have secondary symptoms such as dry stools and irregular bowel movements.
