What is weight loss surgery?

Weight loss surgery effectively treats obesity in people for whom measures such as diet, exercise and medications are not enough. That often coincides with obesity; These include headaches, reflux, diabetes, liver disease, hypertension, joint pain and sleep apnea. After successful bariatric surgery, studies have shown that patients have a lower amount of blood sugar, blood pressure and lower cholesterol levels as well as a decrease in the workload of the heart.

Our first strategy to address weight loss surgery, called laparoscopic sleeve gastrectomy, is the most common procedure among adolescent patients who need to lose weight. This type of surgery reduces the size of the stomach and removes the part of it that produces ghrelin (the hormone that produces hunger). Our second strategy, the laparoscopic Roux-en-Y gastric bypass reduces the size of the stomach. 

It redirects the small intestine to create changes in the intestinal hormones that lead to being less hungry and losing weight. Instead of doing the surgery through a large incision, laparoscopic surgery uses specialized miniature instruments that are inserted through small incisions made in the abdominal wall. Our team has been doing this surgery since 2004.

This technique:

  • promotes faster healing and recovery
  • reduce pain.
  • reduces the chance of an infection

Laparoscopic sleeve gastrectomy.

In laparoscopic sleeve gastrectomy, surgeons change the size of the stomach and reduce it significantly. The surgery works in three main ways:

  1. Because of its small size, the stomach cannot contain so much food.
  2. The procedure removes many of the cells that produce ghrelin, the hormone involved in creating the sensation of hunger.
  3. The stomach empties its contents faster, which causes the intestine to release GLP-1, a hormone that makes you feel satisfied.

Laparoscopic sleeve gastrectomy provides advantages compared to other surgical procedures for weight loss. Patients are less likely to require more surgery due to complications, it is not necessary to build new connections in the intestine, it has a lower risk of nutrient malabsorption, and surgery can later become a gastric bypass if required. And obesity-related diseases after one year, as adolescents who undergo gastric bypass.

Laparoscopic Roux-en-Y gastric bypass.

Gastric bypass surgery changes the process of digestion. Like laparoscopic sleeve gastrectomy, this operation reduces the size of the stomach. But it also causes essential changes in the hormones of the intestines such as ghrelin, GLP-1 and others that result in less hunger, feeling quickly satisfied and weight reduction. 

After surgery, food travels directly to the lower part of the small intestine, skipping the first two sections of it. Therefore increases the risk of nutritional deficiencies. Although gastric bypass may have a higher complication rate, it can also result in the greater long-term success of the surgery and maybe a better option for some adolescents.
