Diagnosis
Your doctor will ask about your symptoms and medical history, and perform a physical exam. Your primary care physician may refer you to a gastroenterologist.
Tests may include the following:
- Blood draw—This tests for low levels of vitamins, minerals, and other nutrients.
- X-rays (with contrast material)—The small bowel and pancreas are examined.
- Small bowel biopsy —A sample of tissue is taken in the small intestine and examined under a microscope.
- A 72-hour stool collection—For this test, you are given a high fat diet, and your stools are collected for 1-3 days and tested for excess fat.
- Pancreatic function test—For this test, you are given a dose of a chemical called bentiromide, which is normally broken down into another chemical called PABA by the pancreas. PABA then gets absorbed and makes its way into the urine; a urine test showing low levels of PABA suggests a problem with the pancreas.
- Xylose absorption test—For this test, you are given a sugary solution called xylose to drink, after which samples of your blood and urine are collected over several hours; low xylose levels indicate an abnormality in intestinal absorption.
