Bariatric surgery, also known as weight loss surgery, is a medical procedure that is used to help people who are severely overweight or obese lose weight. These procedures can be very effective in helping people lose weight and improve their health.

There are many different types of bariatric surgery, but the most common ones include:

  • Gastric sleeve: This procedure removes about 80% of the stomach, leaving a small, banana-shaped pouch. This limits the amount of food that can be eaten at one time.
  • Gastric bypass: This procedure creates a small pouch at the top of the stomach and then connects it directly to the small intestine, bypassing most of the stomach and the first part of the small intestine. This limits the amount of food that can be absorbed by the body.
  • Adjustable gastric banding: This procedure involves placing a band around the upper part of the stomach, creating a small pouch. The band can be tightened or loosened to control the amount of food that can be eaten.
  • Vertical sleeve gastrectomy: This procedure is similar to gastric sleeve, but it removes a slightly larger portion of the stomach.

Bariatric surgery is not a quick fix for weight loss. It is a serious medical procedure that should only be considered after other weight loss methods have failed. However, for people who are severely overweight or obese, bariatric surgery can be a life-saving treatment.

Benefits of Bariatric Surgery

Bariatric surgery can offer many benefits, including:

  • Significant weight loss: People who have bariatric surgery typically lose a significant amount of weight. In some cases, people can lose half or more of their excess weight.
  • Improved health: Bariatric surgery can improve a number of health conditions that are often associated with obesity, such as type 2 diabetes, high blood pressure, sleep apnea, and heart disease.
  • Increased quality of life: Bariatric surgery can improve a person’s quality of life in many ways. People who have lost weight often have more energy, feel better about themselves, and are able to participate in activities that they were unable to do before.

Risks of Bariatric Surgery

Bariatric surgery is a major surgery and, like any surgery, it comes with risks. Some of the risks of bariatric surgery include:

  • Infection: There is a risk of infection at the surgical site.
  • Bleeding: There is a risk of bleeding during or after the surgery.
  • Complications from anesthesia: There is a risk of complications from anesthesia, such as heart problems or breathing problems.
  • Nutritional deficiencies: Bariatric surgery can make it difficult to get enough nutrients, so it is important to follow a healthy diet and take supplements after surgery.
  • Malabsorption: Bariatric surgery can sometimes lead to malabsorption, which is a condition in which the body does not absorb nutrients properly.

Choosing the Right Bariatric Surgery

The best type of bariatric surgery for you will depend on your individual needs and circumstances. Your doctor will be able to help you decide which type of surgery is right for you.

Preparing for Bariatric Surgery

Before you have bariatric surgery, you will need to prepare in a number of ways. This may include:

  • Losing weight: You may need to lose some weight before you have surgery.
  • Making lifestyle changes: You will need to make permanent lifestyle changes after surgery, such as following a healthy diet and getting regular exercise.
  • Meeting with a dietitian: You will need to meet with a dietitian to learn about how to eat after surgery.
  • Meeting with a psychologist: You may need to meet with a psychologist to discuss your expectations for surgery and to help you develop coping mechanisms for the challenges of recovery.

Recovery from Bariatric Surgery

Recovery from bariatric surgery can take several weeks or months. You will need to stay in the hospital for a few days after surgery, and you will need to take it easy for several weeks. You will also need to follow a special diet after surgery.


After you have recovered from bariatric surgery, you will need to continue to follow a healthy diet and get regular exercise. You will also need to see your doctor regularly for checkups.

Bariatric surgery is a serious medical procedure, but it can be a life-changing treatment for people who are severely overweight or obese. If you are considering bariatric surgery, talk to your doctor to learn more about the risks and benefits of this procedure.
