Sucrose intolerance or genetic sucrase-isomaltase deficiency (GSID) is the condition in which sucrase-isomaltase, an enzyme needed for proper metabolism of sucrose (sugar) and starch (e.g., grains), is not produced or the enzyme produced is either partially functional or non-functional in the small intestine. All GSID patients lack fully ...
Sucrose and lactose are called disaccharides because they are made from two simple sugars, and are broken down into these simple sugars during digestion. Sucrose is broken down into glucose and another simple sugar called fructose, and lactose is broken down into glucose and galactose. As a result, lactose, sucrose and other compounds made from ...
Symptoms can manifest in a variety of ways and features might give a clue to the underlying condition. Symptoms can be intestinal or extra-intestinal - the former predominates in severe malabsorption. [citation needed] Diarrhoea, often steatorrhoea, is the most common feature. Watery, diurnal and nocturnal, bulky, frequent stools are the ...
With sucrose intolerance, the result of consuming sucrose is excess gas production and often diarrhea and malabsorption. Lactose intolerance is a similar condition that reflects an individual's inability to hydrolyze the disaccharide lactose. Sucrase is secreted by the tips of the villi of the epithelium in the small intestine.
A diagnosis of essential fructosuria is typically made after a positive routine test for reducing sugars in the urine. An additional test with glucose oxidase must also be carried out (with a negative result indicating essential fructosuria) as a positive test for reducing sugars is most often a result of glucosuria secondary to diabetes mellitus.
Infants with classic galactosemia cannot be breast-fed due to lactose in human breast milk which consists of both galactose and glucose and are usually fed a soy-based formula. [21] Galactosemia is sometimes confused with lactose intolerance, but galactosemia is a more serious condition.
