dumping syndrome

 
nausea, weakness, sweating, palpitation, syncope, often a sensation of warmth, and sometimes diarrhea, occurring after ingestion of food in patients who have had partial gastrectomy (see surgery of the stomach at stomach).
Patient Care. The symptoms experienced during dumping syndrome often are greater after ingestion of highly concentrated and refined carbohydrate foods. Hence the patient is instructed to avoid eating concentrated carbohydrates such as those in desserts and cereals sweetened with granulated sugar. To minimize the effects of the sudden entrance of large amounts of food into the jejunum, small, frequent meals are better than three large ones. Since fluids add to the volume of food ingested in a meal, the patient is encouraged to drink a limited amount of liquid during the meal and to avoid drinking fluids for an hour or two afterward. It also may be helpful for the patient to lie down and relax for about 30 minutes after eating.

dump·ing syn·drome

the syndrome that occurs after eating, most often seen in patients with shunts of the upper alimentary canal that bypass or remove the pylorus; characterized by flushing, sweating, dizziness, weakness, and vasomotor collapse, resulting from rapid passage of large amounts of food into the small intestine, with an osmotic effect removing fluid from plasma and causing relative hypovolemia.

n.
A condition occurring after eating in patients with shunts of the upper alimentary canal and including flushing, sweating, dizziness, weakness, and vasomotor collapse.

dumping syndrome

Etymology: ME, dumpen, to throw down
the combination of profuse sweating, nausea, dizziness, and weakness experienced by patients who have had a subtotal gastrectomy. Symptoms are felt soon after eating, when the contents of the stomach empty too rapidly into the duodenum. The entrance of this hypertonic material into the small intestine causes fluid to shift into the intestine via osmosis. This increased volume causes peristalsis and diarrhea. The loss of fluid from capillaries causes hypotension with resulting weakness and dizziness. A high-protein, high-calorie diet, with small, dry meals taken frequently, should prevent discomfort and ensure adequate nutrition. See also gastrectomy.
A constellation of symptoms seen in ± 20% of those subjected to gastric surgery—e.g., resection, gastro-enterostomy with total gastric vagotomy, and gastric bypass; most inculpated in ‘dumping’ are pyloric ablation and bypass
Lab Increased glucose—worse with high carbohydrate meals—increased heamatocrit, decreased blood volume related to dehydration, decreased K+
Medical management Decreased carbohydrate intake, smaller meals, pectin—a dietary fiber— acarbose, anticholinergics, L-dopa, opiates
Surgical management 2–5% are medical failures, and require surgical conversion to a Roux-en-Y

dump·ing syn·drome

(dŭmp'ing sin'drōm)
A syndrome that occurs after eating, most often seen in patients with shunts of the upper alimentary canal; characterized by flushing, sweating, dizziness, weakness, and vasomotor collapse, occasionally with pain and headache; results from rapid passage of large amounts of food into the small intestine, with an osmotic effect removing fluid from plasma and causing hypovolemia.
Synonym(s): early dumping syndrome, postgastrectomy syndrome.

dumping syndrome

A feeling of drowsiness, with weakness, dizziness, nausea, sometimes vomiting, sweating and palpitations experienced after a meal by people who have had surgical removal of the stomach (gastrectomy).

dumping syndrome

a complex of vasomotor signs associated with eating and the rapid emptying of hyperosmolar gastric contents into the proximal small intestine; believed to be due to the shift of fluid into the gut lumen, intestinal distention and contraction of plasma volume.
