Diseases and Conditions
Blind loop syndrome
Blind loop syndrome occurs when part of the small intestine forms a loop that food bypasses during digestion. The presence of this "blind loop" means food may not move normally through the digestive tract.
Slowly moving food and waste products become a breeding ground for bacteria. The result — bacterial overgrowth — often causes diarrhea and may cause weight loss and malnutrition.
Sometimes called stasis syndrome or stagnant loop syndrome, blind loop syndrome is often a complication of stomach (abdominal) surgery. But blind loop syndrome can also result from structural problems and some diseases. Sometimes surgery is needed to correct the problem, but antibiotics are the most common treatment.
