loss, flatulence, abdominal bloating, edema in the lower extremities resulting from protein deficiency,
muscle weakness, possibly diarrhea or steatorrhea, dehydration, glossitis, and bruising. A variety of

abnormal findings can be associated with malabsorption syndromes, including iron, folic acid, or B12
deficiency anemia; calcium deficiency; vitamins A, B, C, and D deficiencies; and niacin deficiency. There
are as many diagnostics as there are causes of malabsorption. Measurement of fat in the stool is the most
valuable diagnostic for diagnosing malabsorption, and a 3- to 4-day stool collection is advised. Stool
specimens for ova, parasites and culture, and sensitivity will help to rule out infectious causes. Absorption
tests, flat plate of the abdomen, upper GI with small bowel follow- through, endoscopy, and small bowel
biopsy may be necessary for definitive diagnosis.
