Overview

Tropical Sprue can be diagnosed using the following tests and exams:

The stools are usually increased in volume and are either watery, or semiformed.
The finding of fat globules in stool is very suggestive of the presence of steatorrhea.
It is also helpful to exclude some of the parasites causing chronic diarrhea such as Giardia Lamblia, Entamoeba Histolytic.

Performed in all patients with chronic diarrhea to exclude lesions other than sprue such as amebiasis.
In sprue, there is hyperemia of the colonic mucosa without ulcerations.

Shows achlorhydria and changes ranging from superficial gastritis through chronic gastritis to complete gastric atrophy.
