The first symptoms of diarrhea may be stomach cramps or abdomen pain after eating. This can occur anywhere between a few minutes and a few hours after finishing your meal. The stomach pain is often followed by having to run to the bathroom.
The location of your pain after eating also provides clues to the cause. Stomach and intestinal pain can affect the abdomen anywhere from the chest to the navel. Lower abdominal pain after eating more often indicates gastroenteritis or food poisoning, especially if accompanied by diarrhea, nausea or vomiting.
