Anti Dumping



This diet helps to prevent a condition called “dumping syndrome,” which occurs in some patients who have undergone stomach surgery. The symptoms include bloating, nausea, diarrhea, dizziness, weakness, sweating, and rapid heartbeat. They may occur 30 to 60 minutes after eating a meal and then again, 2 to 3 hours after eating.

The early symptoms are caused when concentrated sugar passes too rapidly from the stomach into the intestine. The body dilutes this sugar mixture by bringing fluid from body tissues into the intestine, giving a sense of fullness, cramping, and occasionally, diarrhea. The loss of water from tissues can produce a temporary drop in blood pressure, with resulting weakness and faintness.

The later symptoms are caused by the rapid absorption of sugar into the bloodstream, which raises the amount of blood sugar. A high level of blood sugar signals the body to produce more insulin. The excess insulin, in turn, drives blood sugar levels down. The low blood sugar (hypoglycemia) produces the weakness, hunger, and rapid heart rate that may occur about two to three hours after eating. This diet is really a regular diet with frequent small meals and reduced simple sugars.

Nutrition Facts

Depending upon individual tolerances and food selection, the Anti-Dumping or Post-Gastrectomy Diet is adequate in all nutrients according to the National Research Council’s Recommended Dietary Allowances (RDA). Depending on the type and extent of gastric surgery performed, poor absorption of nutrients, vitamins, and minerals may occur to a significant degree. Some patients may become deficient in iron, calcium, folate, and B-12. The physician may prescribe vitamin/mineral supplementation and B-12 injections.

Special Considerations

  1. Eat six small meals daily to avoid overloading the stomach.
  2. Limit fluids to 4 oz (1/2 cup) during mealtimes. This prevents the rapid movement of food through the upper gastrointestinal tract and allows adequate absorption of nutrients.
  3. Drink liquids 30 to 45 minutes before eating and 1 hour after eating, rather than with meals.
  4. Rest or lie down for 15 minutes after a meal to decrease movement of food from the stomach to the small intestine. This decreases the severity of symptoms.
  5. Avoid sweets and sugars. They aggravate the dumping syndrome.
  6. Avoid very hot or cold foods or liquids, which may increase symptoms in some patients.
  7. Stomach surgery is performed for different reasons, so calorie requirements may vary from patient to patient. For example, a patient who has had surgery for severe obesity will need to be on a weight reduction program. A very thin patient who has had ulcer or cancer surgery will need extra calories.
