Small Intestine Bacterial Overgrowth (SIBO)

Small intestine bacterial overgrowth (SIBO) is a condition caused by an abnormally large number of bacteria present in the small intestine. Bacterial overgrowth can happen for a variety of reasons:

  • Injury or illness that causes the transit time of fecal matter to slow,
  • Excessive alcohol consumption,
  • Reduced stomach acid

Some intestinal diseases such as celiac disease, Crohn’s disease, and diverticulitis have also been associated with development of SIBO.

Some symptoms of SIBO are also symptoms of other GI illnesses and conditions. It is important to discuss your symptoms with Dr. Islam. He will order testing to determine the cause of your symptoms.

You may have SIBO if you have chronic abdominal pain or cramping, bloating, excess gas, diarrhea, and chronic indigestion. Also, tell Dr. Islam if you have trouble with foods that contain fructose, casein, gluten, and/or lactose. Also discuss if you have been diagnosed with inflammatory bowel disease (IBD) or irritable bowel syndrome (IBS).
