The document discusses malabsorption syndromes and provides details about celiac disease. It defines celiac disease as an immune-mediated disorder caused by ingestion of gluten, which damages the small intestine mucosa. Key points include that celiac disease is diagnosed by small bowel biopsy showing villous atrophy and response to gluten-free diet, and that complications can include lymphoma, ulcerative jejunoileitis and dermatitis herpetiformis.

4. Clinical Presentation
 Malabsorption may involve:

– only a single nutrient or a class of nutrients i.e.
specific malabsorption.
 Symptoms and signs of the disease depend
on the deficiency of the nutrient(s) that is
malabsorbed.
