Diarrhea is the increased frequency of bowel movement that is also loose or watery. If diarrhea increases, the possibility of celiac disease is considered. Celiac disease is a serious disease that allows certain macromolecules to pass through the intestinal wall. If blood appears in the stool, ulcerative colitis is likely. Protracted bouts with diarrhea can result in nutritional deficiencies due to the malabsorption of essential nutrients.
Abdominal pain appears in different patterns and with varying intensities.
Cramping occurs because of muscle spasms of the abdominal organs. Severe cramping pain, often called colic, usually occurs from problems with food intakes that exhibit strong allergic response in the patient. Abdominal cramping near the navel is typically from the small intestine, and near the sides, top, and bottom of the lower abdomen, the pain is associated with the colon. Diseases associated with central gastrointestinal tract disorders and diagnoses include depression , migraine , asthma , sinusitis , and fibromyalgia . These diseases have been identified with specific patterns of food allergic response.
