Everything You Should Know About Bariatric Surgery

Bariatric surgery, also known as weight-loss surgery, is a medical procedure used to help people who are excessively overweight or obese lose weight. The procedure involves adjusting the digestive tract to restrict food intake, minimize calorie absorption, or both. In this article, we will discuss everything you should know about bariatric surgery, including the different types of procedures, risks, benefits, and aftercare.

Types of bariatric surgery

There are a few types of bariatric surgery, each one with its own set of advantages and disadvantages. These are the most common types of bariatric surgery:

Gastric sleeve surgery

This treatment includes removing 75-80% of the stomach, leaving a tiny, tube-like part of the stomach. The smaller stomach size restricts the amount of food that can be consumed, resulting in weight reduction. Gastric sleeve surgery is a popular choice because of its simplicity, short hospital stay, and quick recovery time.

Gastric bypass surgery

This type of surgery requires the formation of a tiny stomach pouch that links straight to the small intestine, skipping a section of the stomach and small intestine. The reduced stomach size limits the amount of food that can be ingested, while the bypassed intestine limits the number of calories and nutrients that can be absorbed. Gastric bypass surgery has been used for decades and is considered one of the most successful weight-loss treatments available.

Laparoscopic adjustable gastric banding (LAGB)

The procedure includes wrapping a silicone band around the top section of the stomach, forming a tiny pouch that restricts food intake. The band may be altered to regulate the amount of food that can be consumed, and it is reversible. LAGB is a popular alternative for people who prefer a less intrusive procedure with a shorter recovery period.

Biliopancreatic diversion with duodenal switch (BPD/DS)

This type of procedure combines gastric sleeve and gastric bypass surgery. It includes cutting off a major piece of the stomach and rerouting the small intestine in order to limit the quantity of food that can be consumed as well as the number of calories and nutrients that can be absorbed. BPD/DS surgery is more difficult, with a longer hospital stay and recovery period, but it can result in considerable weight loss.

Risks of bariatric surgery

It is important to understand that bariatric surgery, like any other surgical procedure, includes risks and problems. Here are the most common risks of weight loss surgery:

• Bleeding: If bleeding occurs during surgery, a blood transfusion can be necessary.


• Infection: There is a danger of infection at the surgical site or throughout the body.


• Blood clots: Surgery can increase the likelihood of developing blood clots.


• Nutrient deficiencies: After the surgical procedure, the body may have issues with absorbing important vitamins and minerals, resulting in nutrient deficiencies.


• Dumping syndrome:  Dumping syndrome is a disease that can develop after gastric bypass surgery. It means the fast passage of food from the stomach to the small intestine, which can result in nausea, vomiting, diarrhea, and other symptoms.


• Gallstones: Extreme weight loss can increase the risk of gallstone formation.

Benefits of bariatric surgery

Beyond weight loss, bariatric surgery offers several additional benefits:

• Improved health: Bariatric surgery can improve or address numerous medical issues linked to obesity, including type 2 diabetes, high blood pressure, sleep apnea, and heart disease.


• Increased mobility: Losing weight may improve mobility and lessen pain in the joints, making exercise easier and more enjoyable.


• Improved quality of life: Bariatric surgery can boost self-esteem, reduce feelings of depression and anxiety, and enhance the general quality of life.

Is bariatric surgery right for you?

Bariatric surgery is a big step that should not be done carelessly. Before choosing surgery, people should try to reduce weight through diet and exercise, as well as look into other weight-loss options such as medication or psychotherapy.

People should have a BMI (body mass index) of 40 or higher, or a BMI of 35 or higher with at least one obesity-related health problem, to be a candidate for bariatric surgery. Candidates should also be dedicated to adopting lifestyle changes, such as sticking to a healthy diet and physical activity.
