Gastric bypass is a weight loss surgery in which the stomach is made smaller and part of the intestinal tract is bypassed during digestion. This forces patients to eat less and allows their bodies to absorb fewer calories than normal, both of which aid in weight loss. After surgery the stomach is typically able to hold 4 oz. of food or fluids, but swelling immediately after surgery often requires that patients consume as little as 2 oz. of food or fluids at a time.
Step 1
Eat and drink only 2 oz. of food or fluids at a time immediately following surgery. Your doctor and his staff will advise you what to eat and when, but typically, only a clear liquid diet is allowed post-operative, according to "Handbook of Obesity Treatment." Gelatin, popsicles, broth, tea, water and clear juices are included in a liquid diet.
Step 2
Increase the size of meals to 3 oz. two weeks after your gastric bypass surgery, or when directed to do so by your physician. At this time, soft foods are normally introduced into your diet, according to "Gastrointestinal Nursing." Applesauce, yogurt and protein shakes are included in this diet.
Step 3
Increase your meal size to 4 oz., or 1/4 cup, four weeks following your gastric bypass surgery, or when instructed to do so by your doctor. Oftentimes, all foods in moderation are reintroduced into the diet at this time. However, due to the limited size of the stomach, an emphasis is often placed on low-fat, high-protein options, such as nonfat cheese, chicken breast, lean meat and skim milk.
Tips and Warnings
- Avoid drinking during mealtimes. Fluids will quickly fill up your stomach, leading to a sensation of fullness before your nutritional needs have been met. Instead, wait until after meals to drink fluids.
