Post Gastrectomy Diet
(Restricted Carbohydrate, Increased Protein, Moderately High Fat)
The Post Gastrectomy diet is used to slow the rapid passages of food from the stomach to the intestine and therefore alleviate the dumping syndrome.
Dumping syndrome occurs when the patient experiences nausea, vomiting, and / or diarrhea soon after the ingestion of a meal because the food passed through the stomach and into the upper jejunum too quickly.
Individual tolerances vary greatly, but in general the following principles apply:
- Small, frequent feedings. Breakfast, mid-morning snack, lunch, mid-afternoon snack, supper, and an evening snack.
- High protein and fat content for tissue growth and to increase calories. A protein food should be served with each meal.
- Omission of simple sugars.
- In some cases, milk and other dairy products may be restricted.
- Fluids to be taken only between meals (30 minutes after a meal).
- Avoid extremely hot or cold foods beverages.
- Because this is a highly individualized diet, each patient will progress at his own rate. Small amounts of the “foods not allowed” may be tried gradually.
