Workup:

Tests:
Complete blood count (CBC), Comprehensive metabolic panel (CMP), CT Scan, Lipase, Urinalysis (UA)
Other Specific Tests: D-xylose test, hydrogen breath test, qualitative stool fat test, quantitative stool fat test, schilling test for vitamin B12, secretin stimulation test, small bowel biopsy, stool culture, culture of small intestine aspirate

Treatment
Treatment will depend upon the specific disease or condition causing the malabsorption. If the cause is chronic pancreatitis, taking oral pancreatic enzymes may help. In addition, therapy will include efforts to correct protein, calorie, vitamin and mineral deficiencies. Intravenous fluids, vitamins, and nutrient replacement may be necessary if oral intake is not sufficient.
