Protein-losing enteropathy is an abnormal loss of protein from the digestive tract or the inability of the digestive tract to absorb proteins.
Causes, incidence, and risk factors
There are many causes of protein-losing enteropathy. Any condition that causes serious inflammation in the intestines can lead to protein loss. Some of the more common causes are:
Symptoms can include diarrhea, fever, and abdominal pain. Symptoms depend on the underlying disease that is causing the protein-losing enteropathy.
Signs and tests
Imaging tests may be done to see if there is a problem in the intestinal tract. This may include an CT scan of the abdomen or an upper GI bowel series.
Other tests that may be done include:
- Esophagogastroduodenoscopy (EGD)
- Stool alpha-1-antitrypsin test
The health care provider will treat the condition that caused protein-losing enteropathy.
