Which is the most common weight loss surgery?

The most common types of weight-loss surgery are:

Gastric bypass

Gastric bypass, also known as Roux-en-Y gastric bypass, works by decreasing the amount of food you eat and reducing the nutrition absorption. In this operation, the surgeon staples your stomach, creating a pouch in the upper portion of the stomach.  It makes your stomach smaller and limits the food you can comfortably eat and drink at one time.

In the other part, the small intestine is cut a short distance below the main stomach and connected to the main pouch. So the food flows directly from the pouch to this part of the intestine. The bypassed section is still attached to the main stomach so that the digestive juice can move from the stomach and the first part of the small intestine to the lower part of the small intestine.

Laparoscopic adjustable gastric band

In laparoscopic surgery, an adjustable gastric band is placed around the upper part of the stomach that contains an inflatable balloon. A port is placed under the skin of the abdomen which is connected to the band via a tube. The balloon can be inflated or deflated and size can be adjusted by injecting or removing the fluid from the port. So gastric banding restricts the amount of food that your stomach can hold.

Gastric sleeve surgery or sleeve gastrectomy

In this surgery, a portion of the stomach is separated and removed from the body. The remaining stomach is stapled and formed into a tubelike structure. This small portion of the stomach cannot hold much food.

How do you qualify for weight loss surgery?

Weight loss is a major life-changing procedure. You may require certain guidelines to qualify for weight loss surgery. So, gastric bypass or other weight loss surgery could be your option if :

  • You were unsuccessful with diet and exercise.
  • Your body mass index is 40 or higher.
  • If you have serious problems such as diabetes, high blood pressure or sleep apnea, and your BMI is 35 or more.

The doctors and dietitians evaluate you if you are eligible for weight loss surgery and ready to undergo the process psychologically.  

How much weight do you lose after weight loss surgery

How much weight do you lose after weight loss surgery?

The amount of weight loss depends on the individual and on the type of surgery he or she opts. A study followed people after surgery found that the patient loses on an average of 40% of the access weight. But keep in mind that achieving your goal is not just about taking surgery, it is also about maintaining a healthy lifestyle throughout your life.

Open vs Laparoscopic

In open surgery, your surgeon makes a long incision to open the abdomen and operates with “traditional” medical instruments. Whereas in laparoscopic surgery, or minimally invasive surgery, the surgeon performs the same types of procedures using a few small incisions, a fiber-optic camera, a video monitor and long-handled precision instruments.

People prefer laparoscopic surgery for the following reasons:

  • No cuts, no pain, no wounds
  • Short hospital stay
  • Quick recovery
  • Performed by highly experienced doctors
