Malabsorption in adults: etiology, evaluation, and management
Journal of the American Dietetic Association
|September 1, 1986
Summary
Malabsorption syndrome impairs nutrient digestion and absorption due to various conditions. Diagnosis involves specific tests, and management combines nutritional support with medical treatments to improve nutrient uptake.
Area of Science:
- Gastroenterology
- Nutritional Science
- Internal Medicine
Background:
- Several disease states and treatments negatively impact nutrient digestion and absorption.
- Malabsorption syndrome results from motility disorders, pancreatic insufficiency, bacterial overgrowth, or mucosal changes.
- Symptoms include fatigue, paresthesia, weight changes, altered bowel movements, and laboratory abnormalities due to nutrient losses.
Purpose of the Study:
- To outline the diagnostic workup for malabsorption syndrome.
- To detail the nutritional management strategies for patients with malabsorption.
- To emphasize the importance of a logical diagnostic approach.
Main Methods:
- Absorption workup includes tests for fat absorption, bowel integrity, pancreatic function, and bacterial overgrowth.
- Diagnostic procedures may involve abdominal X-rays, CAT scans, and intestinal biopsy.
- A combination of tests may be used to identify specific absorptive defects.
Main Results:
- Malabsorption syndrome leads to significant losses of macronutrients, electrolytes, minerals, and vitamins.
- A structured diagnostic workup is crucial for accurate identification of absorptive defects.
- Effective nutrition management is key to maximizing nutrient absorption and minimizing losses.
Conclusions:
- A systematic approach to diagnosing malabsorption syndrome is essential to prevent unnecessary testing.
- Comprehensive nutrition management, including parenteral, enteral, and oral feeding, is vital.
- Adjunct medical measures can further enhance nutrient absorption and reduce losses in malabsorption patients.
