Everything About Bariatric Treatment

What is Gastric Sleeve?

Gastric sleeve surgery, also known as sleeve gastrectomy, is a type of weight loss surgery that involves the removal of a large portion of the stomach. The remaining stomach is shaped like a sleeve or tube, hence the name. Gastric sleeve surgery is performed laparoscopically, which means that the surgeon makes a few small incisions in the abdomen and uses specialized instruments to perform the surgery. The procedure is typically performed as a standalone surgery, but it can also be done in combination with other weight loss surgeries such as gastric bypass or duodenal switch. The main goal of gastric sleeve surgery is to help people who are obese or severely obese lose weight and improve their overall health. It works by reducing the amount of food that the stomach can hold, which leads to feelings of fullness and satisfaction with smaller amounts of food. Additionally, the surgery can also help to reduce the production of ghrelin, a hormone that stimulates hunger.

Steps of Bariatric Treatment


The first step in the process is to meet with a bariatric surgeon to discuss your weight loss goals and determine if bariatric surgery is right for you. You will also discuss the different types of surgery and which one is the best option for you.

Pre-surgery evaluation

Before the surgery, you will need to undergo a thorough evaluation to ensure that you are a good candidate for the procedure. This may include a physical exam, laboratory tests, and imaging studies.

Pre-surgery weight loss

Depending on your specific circumstances, you may be asked to lose some weight before the surgery in order to reduce the risk of complications.


The surgery is typically performed under general anesthesia and can take several hours to complete.


After the surgery, you will spend a few days in the hospital to recover. You will be given pain medication to help manage any discomfort and will be closely monitored by the medical team.

Follow-up care

After you are discharged from the hospital, you will need to follow a specific diet and exercise plan in order to support your weight loss and recovery. You will also need to attend follow-up appointments with your surgeon to monitor your progress and address any concerns.

Types of Weight Loss Surgery

There are several types of weight loss surgery, also known as bariatric surgery, that can help people who are obese or severely obese lose weight and improve their overall health. These procedures include:

  • Gastric bypass surgery: This procedure involves creating a small pouch at the top of the stomach and connecting it directly to the small intestine. This bypasses a large portion of the stomach and small intestine, which helps to reduce the number of calories and nutrients the body absorbs.
  • Sleeve gastrectomy: Also known as gastric sleeve surgery, this procedure involves removing a large portion of the stomach, leaving a smaller, tube-shaped stomach.
  • Adjustable gastric band: This procedure involves placing a band around the upper portion of the stomach to create a small pouch that holds less food. The size of the pouch can be adjusted by adding or removing saline solution from the band.
  • Duodenal switch: This procedure involves both the removal of a large portion of the stomach and the rerouting of the small intestine. It is a more complex procedure than other types of bariatric surgery and is typically reserved for people with a BMI of 50 or higher.
  • Mini-gastric bypass: This procedure is similar to traditional gastric bypass surgery but less invasive and involves a shorter hospital stay.
  • Endoscopic sleeve gastroplasty: This procedure involves using an endoscope (a thin, flexible tube with a camera on end) to place sutures in the stomach to create a smaller stomach pouch. It is a newer, less invasive procedure that may be an option for people who are not candidates for traditional surgery.
