Malabsorption |
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]
Causes
Due to Infective Agents
- Whipple's disease
- Intestinal tuberculosis
- HIV related malabsorption
- Tropical sprue
- Traveller's diarrhoea
- Parasites e.g. Giardia lamblia, fish tape worm (B12 malabsorption), round warm, hookworm (Ancylostoma duodenale and Necator americanus).
Due to Structural Defects[1]
- Blind loops
- Inflammatory bowel diseases commonly in Crohn's disease
- Intestinal hurry from post-gastrectomy, post-vagotomy and gastro-jejunostomy
- Fistulae, diverticulae and strictures
- Infiltrative conditions such as amyloidosis, lymphoma and eosinophilic gastroenteropathy
- Radiation enteritis
- Systemic sclerosis and collagen vascular diseases
Due to Mucosal Abnormality
- Celiac disease
- Cows' milk intolerance
- Soya milk intolerance
Due to Enzyme Defeciencies
- Lactase deficiency inducing lactose intolerance (constitutional, secondary or rarely congenital)
- Sucrose intolerance
- Intestinal disaccharidase defeciency
- Intestinal enteropeptidase defeciency
Due to Digestive Failure
- Pancreatic insuffeciencies:
- Bile salt malabsorption
- Terminal ileal disease
- Obstructive jaundice
- Bacterial overgrowth
Due to Other Systemic Diseases Affecting GI Tract
- Hypothyroidism and Hyperthyroidism
- Addison's disease
- Diabetes mellitus
- Hyperparathyroidism and Hypoparathyroidism
- Carcinoid syndrome
- Malnutrition
- Abeta-lipoproteinemia
