This factsheet is about dumping syndrome Our stomach should release food and drink slowly into the small intestine. Causes of dumping syndrome Dumping syndrome is most likely to occur when patients who have an abnormal stomach size or structure eat foods that are rich in sugar.
These include fried foods, dairy products, foods that contain sugar, and specific types of fatty products. There are two phases of this syndrome — the early phase and the late phase.
During the early phase, patients may experience symptoms as early as 30 to 60 minutes after a meal. The late phases of dumping syndrome often occur one to three hours after a patient eats. Symptoms can include:.
The late phases of this syndrome generally occur due to severe upward spikes in blood sugar levels. Call emergency medical services right away. While seemingly unavoidable, dumping syndrome can be circumvented by completely transforming your diet. All gastric bypass surgery patients are advised to cut cookies, sodas, sugary fruit drinks, sweet breads, cakes, alcohol, and the vast majority of dairy products from their diet.
Instead, your diet should be supplemented by complex carbohydrates such as whole-wheat bread and vegetables. Fiber supplements are also recommended, as fiber improves your ability to digest your food properly and take healthy bowel movements.
As previously noted, changing your diet will likely resolve your symptoms. Large pieces of food that make their way into your digestive system can cause complications that could lead to dumping syndrome. To be safe, consider getting into the habit of cutting your meals into tiny pieces. By lying down after eating, you can slow the movement of food into your intestines. By slowing the process of food traveling from your stomach into your intestines, you can digest the food more thoroughly and decrease the chances of experiencing symptoms of dumping syndrome.
Bariatric patients will often learn early on that one of the things that must be cut from their diets is alcohol. Not only can alcohol increase their ability to experience dumping syndrome, but some patients may get drunk faster due to the changes made to their bodies during surgery.
Liquids should only be consumed between meals and should be avoided 30 minutes before eating and 30 minutes after eating. More likely than not, this may cause issues for a bariatric patient though this varies case by case.
