Information for Patients


Also called: Dysentery, The runs, The trots

Diarrhea means that you have loose, watery stools more than three times in one day. You may also have cramps, bloating, nausea and an urgent need to have a bowel movement.

Causes of diarrhea include bacteria, viruses or parasites, certain medicines, food intolerances and diseases that affect the stomach, small intestine or colon. In many cases, no cause can be found.

Although usually not harmful, diarrhea can become dangerous or signal a more serious problem. You should talk to your doctor if you have a strong pain in your abdomen or rectum, a fever, blood in your stools, severe diarrhea for more than three days or symptoms of dehydration. If your child has diarrhea, do not hesitate to call the doctor for advice. Diarrhea can be dangerous in children.

Irritable Bowel Syndrome

Also called: IBS, Irritable colon

Irritable bowel syndrome (IBS) is a problem that affects the large intestine. It can cause abdominal cramping, bloating, and a change in bowel habits. Some people with the disorder have constipation. Some have diarrhea. Others go back and forth between the two. Although IBS can cause a great deal of discomfort, it does not harm the intestines.

IBS is common. It affects about twice as many women as men and is most often found in people younger than 45 years. No one knows the exact cause of IBS. There is no specific test for it. Your doctor may run tests to be sure you don't have other diseases. These tests may include stool sampling tests, blood tests, and x-rays. Your doctor may also do a test called a sigmoidoscopy or colonoscopy. Most people diagnosed with IBS can control their symptoms with diet, stress management, probiotics, and medicine.
