Flatulence and diarrhea may be caused by acute gastroenteritis, rectal cancer, gastrointestinal dysfunction and so on.
1. Acute gastroenteritis: most of them are caused by eating unclean food, resulting in acute infection in the intestines, and intestinal contents can not be completely digested and absorbed, which may lead to diarrhea and bloating symptoms.
2. Rectal cancer: the tumor keeps increasing, presses the intestinal lumen and causes obstruction to the discharge of intestinal contents, which will lead to abdominal distension, and the tumor has obvious stimulation effect on the rectum, which may lead to increased frequency of bowel movement.
3. Gastrointestinal dysfunction: If you have overeaten before, or eat greasy and hard-to-digest food, it may cause gastrointestinal dysfunction, bloating, and then diarrhea.
There are other causes of bloating and diarrhea, such as irritable bowel syndrome, which need to be treated in a timely manner in the hospital.
