Diarrhea without food may be caused by acute gastroenteritis, chronic colitis, irritable bowel syndrome, intestinal cancer and other reasons.
1. Acute gastroenteritis: when the intestinal tract is infected, especially in acute attack, it may lead to edema and congestion of the intestinal mucosa, resulting in diarrhea, abdominal pain and other symptoms.
2. Chronic colitis: For patients suffering from chronic colitis, due to the long-term stimulation of inflammation, it may also lead to diarrhea, loss of appetite, stool shape change and other symptoms.
3. Irritable Bowel Syndrome (IBS): If you have diarrhea without food, especially when you are nervous and anxious, you should consider the possibility of IBS.
4. Colon cancer: some patients who have not eaten for a period of time and have diarrhea, accompanied by symptoms such as change of stool habit, blood in stool, weight loss, etc. are considered to have the possibility of colon cancer. Prompt treatment is recommended.
