Surgical treatment of gastric ulcer and duodenal ulcer and neoplastic lesions consists in excision of a smaller or larger part of the stomach together with the pylorus and the bulbous part of the duodenum.
As a result of these new anatomical-functional relationships, troublesome symptoms called gastric resection syndrome. These symptoms may appear early or late.
Such patients, immediately after meals, especially after fluids containing a lot of carbohydrates (sugars), have a feeling of fullness in the epigastrium and states of sudden exhaustion or even fainting, prone to fainting. These basic symptoms may be accompanied by temporary disturbance of accommodation and vision impairment, a feeling of excessive heartbeat or palpitations (with a feeling of anxiety around the heart). Occasionally, they may also feel hot or sick, and even have occasional vomiting and diarrhea. The standing position usually predisposes to their occurrence, and drinking or eating food while lying down alleviates or prevents their occurrence. Adopting a lying position after the onset of such symptoms alleviates them or causes their complete disappearance.
The onset of these symptoms is explained by the abrupt emptying of the stomach and the resulting rapid stretching of the jejunal intestinal loops. This triggers many water and electrolyte reactions and functional changes that determine the symptoms described in the rest of the gastrointestinal tract and the cardiovascular system.
Late post-surgical syndrome usually occurs 1-2 hours after drinking a highly sweetened drink, or after eating very sweet food or just sugar.
Treatment of the consequences of surgery and prevention of their occurrence in post-resection conditions consists in eating meals in small but frequent portions, with the limitation of carbohydrates, especially simple sugars.
The prevention of late post-resection syndrome is based on the use of an appropriate high-protein and high-fat diet with the limitation of simple carbohydrates, and thus also sweetened drinks. Over time, these ailments disappear as a result of the adaptation of the body and the development of a diet adapted to the new anatomical conditions, e.g. frequent food intake in small amounts.
