Diarrhea in the morning and unformed stools may be related to physiological phenomena, indigestion, acute gastroenteritis and intestinal tumors. 1. Physiological phenomenon: If the patient is cold at night for a long time or eat improperly at dinner, it is easy to cause gastrointestinal dysfunction, resulting in accelerated intestinal peristalsis, which leads to diarrhea in the morning and unformed stools, which is a physiological phenomenon. 2. Indigestion: If you eat too much or indigestible food for a long time, the lack of gastric power causes the food to stay in the stomach, which can cause the stool to be unshaped and frequent, and most of them are manifested as diarrhea. 3. Acute gastroenteritis: If the patient’s long-term dietary irregularities can cause acute gastroenteritis. Due to the intestinal dysfunction caused by pathogen infection, abdominal pain, diarrhea, and even unformed stools can occur. 4. Intestinal tumors: If you suffer from intestinal polyps, rectal cancer, colon cancer and other diseases, they can cause irregular bowel movements, which may be accompanied by abdominal pain, blood in the stool, anemia and other symptoms. There are many other reasons for morning diarrhea and unformed stools, if the symptoms are serious or continue without improvement, it is recommended to go to the regular hospital in time, after clarifying the cause of the disease, under the guidance of the doctor for targeted treatment.
