If the stool is not formed in the morning, it may be due to cold abdomen, indigestion, acute gastroenteritis, chronic enteritis, intestinal tumor and so on. 1. Abdominal cold: Sleeping at night without paying attention to abdominal warmth or eating cold food for dinner leads to faster intestinal peristalsis, so the stool is not shaped in the morning. 2. Indigestion: often overeating, eating food that is not easy to digest, resulting in insufficient gastric power, food in the stomach can not be digested in time, resulting in unshaped stools, bowel movements more often. 3. Acute gastroenteritis: eating food that is infected by bacteria, causing acute gastrointestinal inflammation leading to abdominal pain, unshaped stools, diarrhea, etc. 4. Intestinal tumors: such as rectal cancer, colon cancer and other diseases, resulting in unformed stools, increased frequency of bowel movements, bloody stools, anemia and other symptoms. If you have unformed stool in the morning, it is recommended to seek medical advice to identify the cause of the disease and treat it as early as possible.
