Bariatric surgical procedures cause weight loss by restricting the amount of food the stomach can hold.


Reasons for Bariatric Surgery

Bariatric surgeries can help you lose weight and improve many health problems related to obesity.

Here are six reasons to start the bariatric weight loss surgery process.

  • If diets failed you,
  • If health concerns have you worried about your future,
  • If life has become more limiting,
  • If you have a body mass index (BMI) of 40 or higher or have BMI between 35 and 40 and an obesity-related condition,
  • If you have health problems such as type 2 diabetes, high blood pressure, heart disease, unhealthy cholesterol levels, sleep apnea,
  • If you have knee, hip, or other body pain according to your weight.




According to the last reports of the World Health Organization (WHO), about 25 million people have the classical NIH (National Institutes of Health) criteria for bariatric surgery.



One year after primary surgery 64,2% of patients taking medication for type 2 diabetes no longer needed their medication and correlated with the weight loss achievement.



According to the 2019 IFSO Global Registry Report, over 833,000 bariatric or metabolic interventions were implemented in 61 different countries.







Before the surgery, you discuss the surgical options with your surgeon, who also answers any questions. Based on your history, we may conduct several preoperative tests to meet your needs before, during, and after surgery.

Our expert dietitian teaches you how to build healthy food habits to aid your weight loss. You may be required to begin a supervised diet program.







Depending on the type of procedure you and your surgeon have selected, your surgery will take between one and three hours. We help you through the first days of recovery, encouraging you to get up and walk as soon as possible.







After surgery, you will need to rest and recover. Walking and moving around the house may help you recover more quickly. Start slowly and follow your health care professional’s advice about the type of physical activity you can do safely.

Your health care professional will tell you which foods and beverages you may have and which ones you should avoid. You will need to take dietary supplements that your health care professional prescribes to make sure you are getting enough vitamins and minerals.


Bariatric Methods

The most common bariatric surgery procedures are;

Gastric Bypass

Gastric bypass surgery, also called Roux-en-Y gastric bypass, is done in three steps. First, the surgeon staples your stomach, creating a small pouch in the upper section. The staples make your stomach much smaller, so you eat less because you feel full sooner.

Next, the surgeon divides your small intestine into two parts and attaches the lower part directly to the small stomach pouch. Food will bypass most of your stomach and the upper part of your small intestine, so your body absorbs fewer calories.

The surgeon then reconnects the upper part of the small intestine to a new location farther down on the lower part of the small intestine. This relocating allows digestive juices in the stomach to flow from the bypassed section of the small intestine to the lower part of the small intestine. Therefore, food can be fully digested. Patient appetite and metabolism may affect because the bypass changes the hormones, bacteria, and other substances in the gastrointestinal tract. Gastric bypass is difficult to reverse, although a surgeon may do it if medically necessary.

Sleeve Gastrectomy

The Sleeve Gastrectomy is performed by removing nearly 80 percent of the stomach. The remaining stomach is a tubular pouch that reminds a banana. The surgery reduces the amount of food that can fit in your stomach, making you feel full sooner. The more comprehensive impact seems to be the effect the surgery has on gut hormones that impact various factors as hunger, satiety, and blood sugar control.

Short-term studies show that the sleeve is as efficient as the roux-en-Y gastric bypass in weight loss and improvement or remission of diabetes. There is also evidence that suggests the sleeve, similar to the gastric bypass, is effective in improving type 2 diabetes independent of weight loss. The complication rates of the sleeve fall between those of the controllable gastric band and the roux-en-Y gastric bypass.

Adjustable Gastric Band

Adjustable gastric banding is considered by many to be the least invasive surgery for weight loss. In adjustable gastric band surgery, the surgeon places a ring with an inner inflatable band around the top of your stomach to create a small pouch. With the smaller stomach pouch, eating just a small amount of food will satisfy hunger and promote the feeling of fullness.

The inner band has a circular balloon inside that is filled with saline solution. The surgeon can adjust the inner band to resize the opening from the pouch to the rest of your stomach by injecting or removing the saline solution through a small device called a port that will be placed under your skin.

Biliopancreatic Diversion with Duodenal Switch

Biliopancreatic diversion with duodenal switch, or “mixed surgery,” involves two separate procedures. First, a smaller, tubular stomach pouch is created by removing a portion of the stomach, very similar to the sleeve gastrectomy. Next, a large section of the small intestine is bypassed. That reduces the number of calories and the number of nutrients absorbed. Digestive juices flow from the stomach through the other intestinal tract and mix with food as it enters the colon.
