Post-prandial syndrome appears in the majority of patients after resection (removal) of the total or partial stomach and lasts for several months after the procedure. A premise for resection may be, among others gastric cancer or surgical treatment of obesity (e.g., gastric bypass surgery). Dumping syndrome is a set of reactions caused by the rapid absorption of glucose (sugar) from the intestines after sudden passage of the stomach contents.

How does this happen? 

Removal of the whole stomach or its parts causes disruptions in the proper functioning of the gastrointestinal tract and digestive disorders and absorption of nutrients. As a result of impaired vagus nerve function, the food content passes more quickly to further parts of the digestive system, especially to the small intestine, overloads the intestine and causes a strong discharge of gut hormones into the blood. With time, the digestive system gets used to working in new conditions, and post-prandial discomfort symptoms last for more than 10%. patients after stomach surgery. 

Postprandial syndrome occurs in two early forms, which may occur between 15 and 60 minutes after a meal and late – between 1 and 3 hours after a meal.

Symptoms of postprandial syndrome are so characteristic that they do not require additional diagnostics, but it is definitely worth consulting with a doctor if they persist for a long time. 

The postprandial syndrome usually appears after eating sweet or fatty foods, or fried foods. To prevent ailments, dumping syndrome is used to limit the intake of products that aggravate syndrome symptoms.

People with dumping syndrome should consume 5-6 meals of small size, not too hot and not too cold, every few hours, slowly chewing each bite. Recommended culinary techniques for preparing dishes are cooking in water or steaming and baking in foil. If possible, after eating, the patient should lie down for several minutes. Important in preventing post-prandial syndrome is also drinking fluids – before eating, at least 30 minutes after a meal, between meals, but never while eating. 

Dumping syndrome does not lead to serious diseases, but it can cause a loss of body mass caused by disturbances of absorption of nutrients from food and aversion to food. The goal of post-prandial syndrome treatment is to alleviate ailments in the transient adaptation of the gastrointestinal tract to function in new conditions. The basis of treatment is compliance with dietary recommendations. Sometimes, anticholinergics, inhibiting motor (motor) activity of the digestive tract and supplementation with vitamins and minerals are included in the therapy. 

In the treatment of the post-surgical syndrome, surgical procedures are extremely rare. Correction consists of prolonging the path of food from the stump of the stomach to the duodenum by inserting a small insert made of the small intestine.
