Protein-losing enteropathy

Protein-losing enteropathy is an abnormal loss of protein from the digestive tract. It can also refer to the inability of the digestive tract to absorb proteins.

Causes

There are many causes of protein-losing enteropathy. Conditions that cause serious inflammation in the intestines can lead to protein loss. Some of these are:

  • Bacteria or parasite infection of the intestines
  • Celiac sprue
  • Crohn disease
  • HIV infection
  • Lymphoma
  • Lymphatic obstruction in the gastrointestinal tract
  • Intestinal lymphangiectasia

Symptoms

Symptoms can include:

  • Diarrhea
  • Fever
  • Abdominal pain
  • Swelling

Symptoms will depend on the disease that is causing the problem.

Exams and Tests

You may need tests that look at the intestinal tract. These may include a CT scan of the abdomen or an upper GI bowel series.

Other tests you may need include:

  • Colonoscopy
  • Esophagogastroduodenoscopy (EGD)
  • Small intestine biopsy
  • Alpha-1-antitrypsin test
  • Small bowel capsule endoscopy
  • CT or MR enterography

Treatment

The health care provider will treat the condition that caused protein-losing enteropathy.
