Diagnosing Irritable Bowel Syndrome (IBS) is done by a medical doctor based on the symptoms you experience. The more common IBS symptoms are cramping, bloating, diarrhea and constipation. The normal causes of IBS are eating a bad diet, taking prolonged antibiotics, food poisoning or an operation in the pelvic area. The doctor will perform an examination of the stomach area checking for tenderness in the large intestine area.
Next, the doctor will refer you to a Maryland gastroenterologist for further examination. The gastroenterologist performs a rectal examination in which a tube with a light is inserted inside the rectum. This allows the doctor to see the bowel wall lining as well as the colon. The doctor may take a bowel wall sample for a biopsy to confirm the bowel is normal. This will also allow the doctor to test for any intolerance to gluten.
The doctor may also include a barium enema or barium meal. This allows a radioactive substance to show up in an X-ray. The doctor will probably order blood tests and check for parasites as well.
The point of all these tests is to confirm that nothing else is wrong with the bowel. It is very uncommon to get cancer or a tumor from IBS. IBS is a sign that the bowel is going into spasms. Seeing your doctor can help you diagnose IBS so that treatments can begin.
