In this article we want to dive into the world of bariatric surgery, a procedure that changes the lives of people who have fought against obesity and metabolic diseases probably for decades.

In this complete guide we will cover the definition of what bariatric surgery is, the types of bariatric surgery, its benefits, the risks and the pre and post operative process of bariatric surgery.

What is bariatric surgery?

Bariatric surgery is the branch of general surgery that focuses on performing surgical procedures (some more invasive than others) in which the gastrointestinal tract is modified through various methods.

Contrary to what many people think in relation to the issue of aesthetics, the main objective of bariatric surgery is to improve the general health of the patient. This subspecialty was developed with the intention of achieving considerable weight loss to a greater or lesser extent depending on the procedure, but always with the aim of improving the patient's health from an organic and metabolic point of view, improving glucose levels, blood pressure levels blood pressure, reduce the risk of developing chronic diseases such as diabetes, hypertension, obstructive sleep apnea, heart attacks, strokes, cancers of various types and all other diseases associated with excess weight. Weight is just one of the many parameters that improve with bariatric surgery.

Candidates for bariatric surgery

There is a classification that allows bariatric surgeons to determine what type of bariatric procedure would be ideal for each patient, obviously coupled with a complete clinical history as well as an evaluation by a multidisciplinary team.

Contrary to what many people think, obesity surgery is not the “easy way out” to a problem of lack of attitude or determination. Every successful patient after surgery is a patient who has made a great effort. We have to understand that obesity is a disease that does not depend only on eating less and moving more, but has a broader background that is beyond the purpose of this article.

Definitely not every overweight patient is a candidate, but we invite our watchers not to waste time, if there are any doubts about whether the surgery is for you or not, we invite you to contact us and we can guide you.  

Benefits of bariatric surgery

Bariatric surgery has a large number of benefits that go beyond simply achieving weight loss and improvements in the emotional and psychological aspect that this entails.

To date, bariatric surgery is the only tool that modern medicine has that achieves the remission of certain chronic diseases, which previously could only be controlled with the use of medications. Weight-loss surgery now brings many of these patients to the expected drug-free moment, probably not for life, but for many years, reflecting the excellent quality of life these procedures provide.

What are the options within bariátrics?

There are multiple options within bariatrics, first it is necessary to define if it is really a surgical procedure or an invasive procedure to a greater or lesser extent.

Currently there are endoscopic options, in which the bariatric procedure is performed through a camera that is inserted through the mouth or even without the need for any type of equipment or camera to perform the bariatric procedure, such as a swallowable intragastric balloon, for example.

Types of bariatric surgery

The first thing to define is the type of procedure, that is, how it exerts its effect. Whether it is a "restrictive" or "malabsorptive" procedure or a combination of both. As the terms indicate, the restrictive procedure limits the amount of food the patient eats, usually by reducing the size of the stomach, and the malabsorptive procedure causes the food eaten to not be fully absorbed by the body.

Speaking of the various types of bariatric surgical procedures, there are an infinite number of options and it is completely out of the scope of this article to talk about each one of them. What we can tell you at this time is that currently the two main procedures performed worldwide are #1 the gastric sleeve or vertical sleeve gastrectomy and #2 the gastric bypass or Roux Y, after these two, others follow such as the mini bypass, duodenal switch, sadi, etc. In other articles of our blog we talk about the different types of procedures, especially the most popular and well-known ones, with their respective pros and cons.

Bariatric Surgery Risks and Considerations

Definitely, bariatric surgery is not for everyone; as we said before, patients should be aware that it is a surgery and that having an operation does not mean that they can forget to make an important effort both to lose weight initially and to maintain said weight loss over the years.

The success of which we spoke previously is precisely this, to be able to maintain the results for an indeterminate time to maintain good health.

Preoperative Phase

All patients must be thoroughly evaluated in order to determine their general health, the optimal type of procedure for their situation and their preparation based on this, either through consultations with the cardiologist, pulmonologist, endocrinologist, internist, etc.

It should also be taken into account that at least in Obesity Free we ask all patients with a body mass index above 37 a very specific preoperative diet, which we provide and its duration will depend on the degree of obesity of each patient. The reason for this is explained in our preoperative diet article.

Postoperative Phase

The most important part of the process after performing weight loss surgery is 100% adherence to the indications of your bariatric surgeon and his team, specifically supplementation and diet, as well as its progression in its different phases. All of this information should be provided to you in detail before your surgery so that you can prepare ahead of time.

It is also very important for us that you get your follow-up consultations, which are included in the initial budget to make sure that you are following the best possible course, since this will help you obtain the best results both in weight loss , as in your physical constitution and your optimal nutritional status.


Bariatric surgery is a great advance in medicine that has been in progress for many decades, but in the last two decades it has achieved a great boom for three main reasons: its dissemination in the media, mainly the Internet, due to its accessibility from the economic standpoint and by the advent of new technologies from the anesthetic and surgical point of view, such as laparoscopy or minimally invasive surgery.
