Dr. Rincon performs gastric bypass surgery via the Roux-en-Y procedure, which is generally considered to be the best surgical procedure for the treatment of morbid obesity in the United States. He reduces the functional portion of your stomach, which is normally the size of a football, to a pouch that’s the size of a golf ball. Then the first portion of the small intestine is divided, and the bottom is attached to the small stomach pouch, creating a limited route through which food can pass.
After the surgery, the food passes into the small stomach pouch and through the connected bottom portion of small intestine, bypassing most of the stomach and first part of the small intestine. Because most of the digestive juices pass through the bypassed portion, they don’t mix with the food, so there’s less nutrient absorption, which contributes to weight loss.
In addition, you eat less because your stomach is smaller and causes you to have a sensation of fullness after eating only a small portion of food.
Your body mass index (BMI) helps Dr. Rincon determine if you’re a candidate for gastric bypass surgery. BMI is a calculation of the ratio of your height and weight that’s used to estimate body fatness.
To be a candidate for Roux-en-Y gastric bypass surgery, you must have a BMI of at least 40, or a BMI of 35 if you also suffer from certain significant medical conditions, such as diabetes or hypertension.
You usually stay in the hospital for two days after surgery. You follow a liquid diet with protein shakes for the first few days after gastric bypass surgery, and then advance to a pureed diet. Since dehydration can be a concern, the team asks patients to take in at least 32 to 48 ounces of liquid daily after the surgery.
Approximately one month after surgery, you begin to eat more regular table foods. You learn how to eat differently, which involves chewing food carefully and drinking most liquid between meals, rather than with your meals. You’ll also discover that eating the wrong foods, such as sweets or fatty foods, can make you ill. About three months after surgery, you’ll have transitioned to your long-term maintenance diet.
You experience the most rapid weight loss during the first month, sometimes at the rate of 20 pounds a month. The process isn’t easy, however, as you may face cravings and feel low on energy due to the decreased calorie intake.
Many patients lose 75-80% of their excess body weight within the first two years after surgery.
