Small Intestinal Bacterial Overgrowth

Small intestinal bacterial overgrowth occurs when a larger-than-usual amount of microorganisms grows in a part of the digestive tract where there are normally few, which alters digestion and the absorption of nutrients.

Common symptoms: It can cause abdominal bloating, gas, belly discomfort, diarrhea and, in some cases, weight loss or discomfort after eating.

Common causes: It is usually related to changes in intestinal movement or to conditions that alter the anatomy or the flow within the intestine.

Which specialist treats it? The gastroenterologist is the one who studies this type of digestive abnormality and, in minors, the pediatric gastroenterologist. If you have persistent digestive discomfort, a professional review helps identify its source.
