Surgery of obesity and minimal invasion

It is the set of surgical procedures used to treat obesity that seek a decrease in body weight; As an alternative to the treatment, other non-surgical means are also used.

General Surgery

The surgeon is responsible for carrying out intervention procedures for conditions that are acute or chronic and require invasive management of the organism. Having the endorsement of a college of professionals in surgery is a guarantee of integrity and quality in the care provided to our patients.


Before any surgical procedure, an adequate systemic evaluation of the patient should be carried out, beginning with the respiratory, circulatory and metabolic systems; continuing with the adequate knowledge of his medical history of medical relevance.


The surgeon works by improving the function of the human body by intervening in the endocrine system of the body.

Physical medicine and rehabilitation

Exercise and physical activity are vital for the patient who follows a weight control protocol, it is our task to indicate the type and special characteristics of the same in order to achieve the expected goals without damaging the organism during the monitoring of the process.

Bariatric psychology

One of the pillars of the management of the person with overweight and obesity is the assessment by the bariatric psychology service, who will help us to manage the weak points and strengthen the strengths of the individual in order to carry out an integral and multidisciplinary follow-up. of the weight control protocol.


Nutrition is one of the cornerstones of the development of people and much more important for obese patients but in a specialized and personalized way according to their condition and bad eating habits. This is why the attention provided by a nutritionist effectively complements the management of our patients together with the rest of the specialties. The control of the portions and the schedules of the food is part of a reeducational process that will help to achieve the proposed objectives.

Plastic and aesthetic surgery

After a Bariatric Surgery or due to changes in diet and exercise extreme weight loss can cause other types of aesthetic problems. Patients often have loose skin and no elasticity to accommodate a thinner shape; this is where the specialists intervene to support patients with different options.


Is the medical specialty that deals with all diseases of the digestive system consisting of: esophagus, stomach, liver and bile ducts, pancreas, small intestine (duodenum, jejunum, ileum), colon (large intestine) and rectum.


It is a diagnostic technique, used in medicine that consists of the introduction of a camera or lens inside a tube or endoscope through a natural orifice, a surgical incision or a lesion for the visualization of a hollow organ or body cavity.


In some cases, overweight and obesity cause certain diseases in the circulatory system and the heart, which is why it is important to be evaluated by a specialist in the field. When weight management is carried out, risk factors and conditions of this type decrease, so that the need for medication and strict controls are much lower.


It is common for the overweight and obese patient to present respiratory problems, because excess tissue prevents this function from being properly carried out by the body, for example, when sleeping an overweight person can even stop breathing for a few seconds, this is why an assessment by the pulmonologist is an important part of the protocol of general assessment and weight control.
