The Gastric Bypass allows food to pass through the digestive system faster. This technique consists of reducing the size of the stomach and connecting it to the section of intestine that has less capacity to absorb food, bypassing the part with the highest absorption capacity. Therefore it is a mixed technique (restrictive and bad absorptive), the reduced capacity of the stomach restricts the amount of food that can be consumed and the bypass reduces the calories absorbed. In this way, the body does not receive as much energy and loses weight.

Who is the ideal candidate to undergo a Gastric Bypass?

It is normally performed on people with a Body Mass Index (BMI) greater than 40 Kg / m2. Also in people with a lower BMI but with some disease related to obesity.

How much weight am I going to lose?

Most patients enjoy a weight loss of between 4 and 8 kilos per month during the first year. On average, an excess weight loss of 60% and 70% is maintained after 10 years.

Why a Gastric Bypass?

• It is the surgical technique for weight loss considered the “gold standard” due to its effectiveness, proven in numerous studies of high scientific rigor.
• Produces significant short-term weight loss that is sustained over the long term.
• The redirection of the digestive system produces changes in the intestinal hormones, promoting early satiety, suppressing hunger and reversing the main mechanisms by which morbid obesity induces Type 2 Diabetes.
• It presents the best results in terms of resolution of diseases derived from obesity.


The Gastric Sleeve, also known as Vertical Gastrectomy, consists of reducing the size of the stomach by approximately 75%, resulting in a stomach with a decreased capacity to store food by up to 25%. In this way a faster and more lasting feeling of satiety is experienced, allowing you to eat less frequently and in less quantity. Fundamentally it causes a restriction of the ingestion. In this technique, the intestines remain intact, which reduces the risk of complications. In addition, the stomach maintains its function.
