Stomach cramps are caused by several conditions, such as inflammation, intestinal obstructions or loss of blood supply to a related organ, according to MedicineNet. Stomach cramps is a nonspecific term that is often used to describe pain anywhere in the abdominal area, and the possible causes vary depending on the affected organ. Potential conditions related to stomach cramps include appendicitis, Crohn's disease, food poisoning and irritable bowel syndrome.
Constipation, indigestion, menstrual cramps, lactose intolerance and a stomach virus are some of the most common causes of stomach cramps, according to WebMD. If pain in the abdominal area recurs frequently, is severe, or is accompanied by either a fever, signs of dehydration, painful urination, an inability to pass stool or an extremely tender abdomen, patients should contact a health care professional immediately. Other common causes of stomach cramps include gastroesophageal reflux disease, kidney stones, urinary tract infection, gallstones or endometriosis.
Some of the main causes of stomach cramps include intestinal disorders, abnormal growths, infections or blockages, according to Healthline. An infection located in a patient's blood stream, intestines or throat can also bring bacteria to his digestive tract and lead to stomach cramps. Abnormalities in a person's digestion, such as constipation or diarrhea, can also be caused by these infections. Vomiting, acid reflux and stress are known causes of stomach cramps, as well.
