Information for Patients

Lactose Intolerance

Also called: Dairy product intolerance, Lactase deficiency, Milk intolerance

Lactose intolerance means that you cannot digest foods with lactose in them. Lactose is the sugar found in milk and foods made with milk. After eating foods with lactose in them, you may feel sick to your stomach. You may also have

  • Gas
  • Diarrhea
  • Swelling in your stomach

Your doctor may do a blood, breath or stool test to find out if your problems are due to lactose intolerance.

Lactose intolerance is not serious. Eating less food with lactose, or using pills or drops to help you digest lactose usually helps. You may need to take a calcium supplement if you don't get enough of it from your diet, since milk and foods made with milk are the most common source of calcium for most people.

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
