Blind loop syndrome occurs when digested food slows or stops moving through part of the intestines. This causes an overgrowth of bacteria in the intestines. It also leads to problems absorbing nutrients.

What are the causes of Blind Loop Syndrome?

The name of this condition refers to the "blind loop" formed by part of the intestine that is bypassed. This blockage does not allow digested food to flow normally through the intestinal tract.

The substances needed to digest fats (called bile salts) do not work as they should when a section of the intestine is affected by blind loop syndrome. This prevents fat and fat-soluble vitamins from being absorbed into the body. It also leads to fatty stools. Vitamin B12 deficiency may occur because the extra bacteria that form in the blind loop use up this vitamin.

Blind loop syndrome is a complication that occurs:

  • After many operations, including subtotal gastrectomy (surgical removal of part of the stomach) and operations for extreme obesity
  • As a complication of inflammatory bowel disease

Diseases such as diabetes or scleroderma may slow down movement in a segment of the intestine, leading to blind loop syndrome.

What are the symptoms of Blind Loop Syndrome?

Symptoms include:

  • Diarrhea
  • Fatty stools
  • Fullness after a meal
  • Loss of appetite
  • Nausea
  • Unintentional weight loss

What are the current treatments for Blind Loop Syndrome?

Treatment most often starts with antibiotics for the excess bacteria growth, along with vitamin B12 supplements. If antibiotics are not effective, surgery may be needed to help food flow through the intestines.
