dumping syndrome

Dumping syndrome is the rapid entrance of food directly into the jejunum (portion of small intestine). The hypertonic solution in the gut draws fluid from the circulating blood volume into the intestine, thereby reducing the blood volume and producing syncope (fainting). The onset of symptoms may occur during the meal or from five to 30 minutes after the meal. The attack can last 20 to 60 minutes. Symptoms include weakness and faintness, accompanied by profuse perspiration and palpitations. This reaction appears to be greater after the ingestion of sugar. Sugar is the most quickly processed food and thus should be avoided with the dumping syndrome. These symptoms are also attributed to the sudden rise in blood sugar (hyperglycemia). People who experience the dumping syndrome should eat a low-carbohydrate, high-fat, high-protein diet; drink fluids only between meals; avoid eating large amounts of food at one time; and rest after meals for 30 minutes. Sometimes anticholinergic (antispasmodic) drugs may be prescribed to be taken before meals.
