Morbid Obesity : Diet After Surgery

Many prospective patients are concerned that they will never be able to eat "normally" again. This is not true. Initially the volumes of food that can be eaten at one sitting will be very small. For the Roux-en-Y gastric bypass, the new stomach will have the volume of a small egg. The new stomach will stretch over time and the eventual capacity of the stomach will be between 䯠1 cup. Most bariatric surgeons recommend that their patients eat smaller volumes of food at meals and eat more frequently over the course of the day. It is also important to refrain from eating foods that are high in refined sugars and concentrated fats. These types of foods will likely cause dumping syndrome and should be avoided, especially for those that have undergone the Roux-en-Y gastric bypass. Nausea and vomiting are not uncommon in the period immediately after the surgery. This generally improves as the new stomach stretches and the new dietary regimen is gotten used to. If nausea and vomiting are persistent and are associated with persistent or new onset pain, this could signify a more significant problem and care should be sought immediately. Drinking at least 8 cups of water a day is also recommended to prevent dehydration. The water should be taken in-between meals as this will also help to prevent dumping syndrome. In addition to these dietary changes, patients are generally asked to take supplemental vitamins to help prevent malnutrition. Vitamin B12 may also have to be taken to prevent or treat anemia.
