A 3 year old girl with Down's syndrome became lethargic and withdrawn, and investigations showed a specific malabsorption of vitamin B12 without proteinuria.

Vitamin A deficiency (VAD) can cause a range of ocular manifestations, including night blindness, conjunctival and corneal xerosis and keratomalacia. It is an important cause of preventable blindness. Although usually a result of malnutrition, VAD can accompany malabsorption syndrome. We report a case of VAD as manifested by Bitot's spots and eventually diagnosed to have celiac disease. It is, ...

Concern exists that increasing fructose consumption, particularly in the form of high-fructose corn syrup, is resulting in increasing rates of fructose intolerance and aggravation of clinical symptoms in individuals with irritable bowel syndrome. Most clinical trials designed to test this hypothesis have used pure fructose, a form not commonly found in the food supply, often in quantities and c...

BACKGROUND Fructose malabsorption is characterized by the inability to absorb fructose efficiently. As a consequence fructose reaches the colon where it is broken down by bacteria to short fatty acids, CO2, H2, CH4 and lactic acid. Bloating, cramps, osmotic diarrhea and other symptoms of irritable bowel syndrome are the consequence and can be seen in about 50% of fructose malabsorbers. Recently...

BACKGROUND Carbohydrate malabsorption of lactose, fructose and sorbitol has already been described in normal volunteers and in patients with functional bowel complaints including irritable bowel syndrome. Elimination of the offending sugar(s) should result in clinical improvement. OBJECTIVE To examine the importance of carbohydrate malabsorption in outpatients previously diagnosed as having f...

Dietary fructose induces abdominal symptoms in patients with fructose malabsorption, but there are no published guidelines on its dietary management. The objective was to retrospectively evaluate a potentially successful diet therapy in patients with irritable bowel syndrome and fructose malabsorption. Tables detailing the content of fructose and fructans in foods were constructed. A dietary st...
