If your doctor suspects that you are suffering from blind loop syndrome, you will be referred to a gastrointestinal specialist in the hospital. You will undergo a number of diagnostic tests including:
X-rays and CT scans of your abdomen
Barium X-rays
CT enterography
These tests are designed to identify any abnormal physiology within the small intestine.
Further tests are usually carried out to determine the presence of bacteria within the small intestine, including:
hydrogen breath test
D-xylose breath test
bile acid breath test
fecal fat test
small intestine fluid culture test
Based on the result of these tests a definitive diagnosis may be made and suitable treatment commenced.
