Weight Loss Surgery: Bariatric surgery

Over time, people who are overweight or suffering from obesity have used different alternatives like exercise, diet, and medications in order to treat their weight issues. Still, the vast majority of people end up re-gaining the weight they’d lost, and they tend to struggle for years without ever achieving their desired weight.

Some patients even experience complications associated with their weight like hypertension, heart attacks, hormonal imbalances, erectile disfunction, diabetes, strokes, and joint damage, among others.

Today, BARIATRIC SURGERY is the best alternative to achieve long-term weight loss. Procedures like the gastric sleeve and gastric bypass surgery have been shown to be the best choice for sustainable weight loss that lets patients achieve a healthy weight.Both techniques even work to regulate the production of hormones associated with obesity, like Ghrelin (known as the “hunger-hormone”).

Gastric Sleeve

This is a minimally invasive weight-loss procedure of about 40 minutes. Through laparoscopic surgery (which uses a camera of about 0.5 CM), the surgeon reduces the size of the patient’s stomach by about 80%. Due to the reduced stomach size, patients will feel satisfied sooner, after having eaten significantly less food.

Furthermore, the stomach will not be able to secrete as many hunger-inducing hormones. One hormone that will be limited is Ghrelin. This hormone, which is responsible for inducing feelings of hunger, is produced in a section of the stomach that will be removed. After the procedure, the levels of this hormone are reduced and, as a result, patients feel fewer hunger impulses and hunger-related anxiety. (Read more...)

Gastric Bypass

Gastric bypass is a weight-loss surgery which changes how the stomach and the small intestine deal with ingested food.

After the surgery, the stomach will be smaller, and it will feel full after eating less food.

The ingested food no longer passes through various parts of the stomach and the small intestine that absorb food. Because food bypasses these sections, the body does not receive all of the calories from the consumed food. (Read more...)

  • The surgery is carried out with a laparoscope (a camera of about 0.5 cm). ⚡️Fast recovery

  • This technique works by modifying part of the digestive system, reducing the amount of food the patient can consume, regulating hormonal secretions (which control anxiety and satiety), and by limiting the number of calories and fat absorbed in the intestine.
