Bariatric surgery is a type of weight-loss surgery that involves making changes to the digestive system. There are several types of bariatric surgeries, each with its own unique benefits and potential risks. The amount of weight you can lose with bariatric surgery depends on several factors, including your age, gender, starting weight, and the type of surgery you undergo. Gastric bypass surgery involves creating a small pouch at the top of the stomach and connecting it directly to the small intestine. Sleeve gastrectomy involves removing a large portion of the stomach, leaving behind a narrow tube-like structure. Adjustable gastric banding involves placing an inflatable band around the top of the stomach, creating a small pouch with a narrow opening into the rest of the stomach. On average, patients can expect to lose about 60-70% of their excess body weight within one to two years after gastric bypass surgery, about 50-60% of their excess body weight within one to two years after sleeve gastrectomy, and about 40-50% of their excess body weight within one to two years after adjustable gastric banding. However, individual results may vary and your doctor will be able to provide more specific information based on your unique circumstances.
Introduction
Bariatric surgery is a type of weight-loss surgery that involves making changes to the digestive system. It is usually done in people who are very obese and have not been able to lose weight through diet and exercise. The amount of weight you can lose with bariatric surgery depends on several factors, including your age, gender, starting weight, and the type of surgery you undergo. In this article, we will discuss the different types of bariatric surgeries and their expected weight loss outcomes.
Types of Bariatric Surgeries
There are several types of bariatric surgeries, each with its own unique benefits and potential risks. Here are some of the most common types:
Gastric Bypass Surgery
Gastric bypass surgery involves creating a small pouch at the top of the stomach and connecting it directly to the small intestine. This reduces the amount of food that can be eaten and absorbed by the body. On average, patients can expect to lose about 60-70% of their excess body weight within one to two years after surgery.
Sleeve Gastrectomy
Sleeve gastrectomy involves removing a large portion of the stomach, leaving behind a narrow tube-like structure. This reduces the amount of food that can be eaten and also affects hormones that regulate hunger and satiety. Patients can expect to lose about 50-60% of their excess body weight within one to two years after surgery.
Adjustable Gastric Banding
Adjustable gastric banding involves placing an inflatable band around the top of the stomach, creating a small pouch with a narrow opening into the rest of the stomach. This restricts the amount of food that can be eaten. Patients can expect to lose about 40-50% of their excess body weight within one to two years after surgery.
Expected Weight Loss Outcomes
The amount of weight you can lose with bariatric surgery depends on several factors, including your age, gender, starting weight, and the type of surgery you undergo. Here are some general guidelines for expected weight loss outcomes:
Gastric Bypass Surgery
On average, patients can expect to lose about 60-70% of their excess body weight within one to two years after gastric bypass surgery. For example, if you were 100 pounds overweight before surgery, you could expect to lose about 60-70 pounds after surgery.
Sleeve Gastrectomy
Patients can expect to lose about 50-60% of their excess body weight within one to two years after sleeve gastrectomy. For example, if you were 100 pounds overweight before surgery, you could expect to lose about 50-60 pounds after surgery.
Adjustable Gastric Banding
Patients can expect to lose about 40-50% of their excess body weight within one to two years after adjustable gastric banding. For example, if you were 100 pounds overweight before surgery, you could expect to lose about 40-50 pounds after surgery.
It is important to note that these are just general guidelines and individual results may vary. Your doctor will be able to provide more specific information based on your unique circumstances.
