Information for Patients

Malabsorption Syndromes

Your small intestine does most of the digesting of the foods you eat. If you have a malabsorption syndrome, your small intestine cannot absorb nutrients from foods.

Causes of malabsorption syndromes include

  • Celiac disease
  • Lactose intolerance
  • Short bowel syndrome. This happens after surgery to remove half or more of the small intestine. You might need the surgery if you have a problem with the small intestine from a disease, injury, or birth defect.
  • Whipple disease, a rare bacterial infection
  • Genetic diseases
  • Certain medicines

Symptoms of different malabsorption syndromes can vary. They often include chronic diarrhea, abnormal stools, weight loss, and gas. Your doctor may use lab, imaging, or other tests to make a diagnosis.

Treatment of malabsorption syndromes depends on the cause.

  • Blind loop syndrome
  • D-xylose absorption
  • Fecal fat
  • Lower GI Series - NIH (National Institute of Diabetes and Digestive and Kidney Diseases)
  • Malabsorption
  • Short bowel syndrome
  • Small bowel bacterial overgrowth
  • Stools - floating
  • Whipple's Disease - NIH (National Institute of Diabetes and Digestive and Kidney Diseases)
