Gastrointestinal problems caused by rapid gastric emptying<\/h2>\n

People with dumping syndrome experience excessively rapid emptying of the stomach\u2014literally a ‘dumping’ of food. With dumping syndrome, food that has not yet been sufficiently digested reaches the small intestine in pieces. This can cause a range of unpleasant gastrointestinal reactions. On this page, Darmklachten.nl provides more information about dumping syndrome. [\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]\n

What causes dumping syndrome?<\/h2>\n

Dumping syndrome is almost always the result of surgery in which part or all of the stomach has been removed, such as a gastric bypass. Sometimes the symptoms are caused by damage to the nerve that controls the stomach, the vagus nerve. Two symptom patterns can be distinguished in dumping syndrome:<\/p>\n

    \n
  1. Early dumping symptoms: these occur shortly after a meal and may be noticeable within half an hour.<\/li>\n
  2. Late dumping symptoms: these occur approximately one to three hours after a meal.<\/li>\n<\/ol>\n

    The two symptom patterns can occur together or separately.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column]

Normally, food is first thoroughly ground and mixed in the stomach before being passed to the small intestine in small portions. Early dumping symptoms therefore occur when the stomach does not break the food down sufficiently. A poorly functioning sphincter that allows too much food through at once can also cause these symptoms.

    Late dumping symptoms<\/h2>\n

    Normally, food remains in the stomach for about two to three hours so that it can be ground and mixed. It then passes to the small intestine in small portions, when the small intestine is ready to receive it. Late dumping symptoms occur because the small intestine is not yet ‘ready’. The pieces of food are still too large and reach the small intestine too quickly. The digestive juices needed\u2014bile and pancreatic juices\u2014are then not yet present in sufficient amounts in the small intestine.<\/p>\n

    How can you recognise early dumping syndrome?<\/h2>\n

    During early dumping, highly concentrated food in the small intestine attracts a large amount of fluid. This fluid is drawn from the surrounding blood vessels. In some cases this can amount to three to four litres. This can cause:<\/p>\n
