How Much Weight Will I Lose With Gastric Bypass?

Bariatric procedures are some of the greatest advancements in weight loss medical science. They allow for weight loss results that are simply not possible with diet and exercise alone. For this reason, they’ve become a powerful solution for patients struggling with obesity.

 

A common question that many people have on their minds before they go in for surgery is “How much weight will I lose with gastric bypass Long Island?” This question depends on several factors, and in order to understand why such great weight loss is possible, one must understand how the procedure works.

 

How Does Gastric Bypass Work?

 

The gastric bypass, otherwise known as the roux-en-y gastric bypass, is a procedure that combines both restrictive and malabsorptive elements to produce weight loss that isn’t possible without surgery.

 

The procedure is done by taking the stomach and creating a small pouch within it. The rest of the stomach is no longer able to hold food, effectively reducing the total stomach volume usable for holding food and liquids. Then, the stomach is attached to a lower part of the intestine, bypassing the upper part of the intestine. This reduces the amount of calories that can be absorbed from food.

 

The result is that the patient can only eat a very small portion of food at one time. Moreover, fewer calories are absorbed from the ingested food.

 

Gastric bypass patients report a significant reduction in hunger and a lessened ability to eat large amounts of food. Patients find that they’re able to keep the weight off for a long time due to how the procedure reduced their food intake.

 

Expected Weight Loss After Gastric Bypass

 

 

Average Weight Loss After Gastric Bypass

 

Patients can expect to lose around 50% of their excess weight in their first year after surgery. A patient’s excess weight is calculated by subtracting their ideal weight from their current weight. If a patient weighs 350 pounds and their ideal weight is 150 pounds, they have 200 pounds of

excess weight and can expect to lose around 100 pounds in their first year, ultimately weighing 250 pounds after surgery.

 

Weight loss continues after their first year, with patients generally reaching their final weight after about two years post-op.

 

Factors Affecting Weight Loss After Gastric Bypass

 

 

Adherence to the post-op diet

 

The post-op diet is a highly restrictive diet employed in the first month after surgery. It serves two purposes. First, it allows for a ramping reintroduction of foods after surgery to prevent serious gastrointestinal problems. Second, it kickstarts rapid weight loss due to how few calories the patient is eating during this diet.

 

How well a patient adheres to this diet affects the amount of weight they’ll lose as a result of surgery. We recommend that patients follow the diet to a “T” and make sure to make their hydration and protein goals.

 

Continued healthy diet

 

After the post-op diet, patients are able to eat many more kinds of foods again. At this stage, it’s very important that patients commit to eating a low-fat and low-sugar diet made up primarily of whole foods.

 

It’s not unheard of for patients to return to old eating behaviors, despite the fact that it’s much harder for them to do so. To prevent this, patients are asked to stick to a healthy meal plan and keep indulgences to a minimum.

 

Addition of an exercise regimen

 

Patients who exercise have better weight loss results than those who don’t. This is because exercise helps burn calories, build muscle, and improve cardiovascular health.

 

In the first month after surgery, patients should commit to very light exercise consisting of brisk walks. After the incisions heal, patients are able to add swimming to their exercise routine, which is easy on the joints. Patients can add resistance and weight training once their doctor has given them permission to do so.
