Intra-gastric balloon

It involves inserting a ball of salt into the stomach, which is to be halved. By reducing the amount of food in the stomach, the feeling of satiety first appears, thus reducing the amount of daily food.

The operation is quite safe, does not require hospitalization, does not require anesthesia, and does not usually have complications. The deflated balloon is introduced by endoscopy and, once inside the abdomen, it is inflated with saline and the valve is sealed. Although there is already a more advanced method: ingestible intragastric balloon. It will be enough to swallow the capsule attached to the thread. Once the balloon bursts in the stomach. A less aggressive approach.

Gastric band

An inflatable band is placed around the upper abdomen, creating a kind of small abdomen. Again, the goal of the intervention is to reduce the volume of the stomach so that a feeling of satiety first appears. In addition, the band prevents the stomach from expanding, allowing it to receive more food.

First, food passes slowly from the small stomach to the rest of the stomach through a small hole, the diameter of which is regulated by inflating the band with salt. The first inflation of the band is usually done around the sixth week, after which it is inflated only when the patient stops losing weight.


We can think of this operation as an aesthetic operation, as it does not affect the digestive process, but rather removes excess fat and skin directly from the abdomen, which is usually the part where it accumulates the most. Is.

This operation requires general anesthesia, and no longer laparoscopy, it is a more invasive procedure in which the abdominal skin is removed from the scalpel, the excess fat and skin is removed, even the abdomen. Muscles are strengthened by sutures if they are too light.

The operation usually requires general anesthesia, lasts for about 2-4 hours and after the operation you have to wear a belt to help the area more. Here, at the very least, there are scars and it takes time for the shape of the abdomen to become uniform.

Gastric sleeve

Here we have already undergone more invasive surgery and, although this is done through laparoscopy, the size of the stomach is reduced by 75-80% by removing part of it (gastrectomy). The stomach is cut vertically to form a banana-shaped "sleeve".

The operation lasts between one and three hours and requires hospitalization, between two and three days. The stomach maintains all its functions, it has reduced its volume considerably, so the feeling of fullness will appear soon.


It can also be considered a cosmetic operation. It is best known when it comes to removing fat from the middle, but it is useless if we continue bad eating habits after liposuction, because there is nothing involved in the digestive system.

It consists mainly of extracting fat using a syringe that sucks it out. The problem here is that the skin will be excessive before a significant reduction in fat and it will not be aesthetically pleasing, so another operation will have to be done later to reduce this extra skin.

It does not require hospitalization and the anesthesia is localized, so in a few hours we can get rid of a few kilos of fat.

Gastric plexus

This operation is similar to the previous operation, except that there is no gastrectomy but gastroplasty.

The stomach retains all its functions and its volume is reduced by 75-80%. It does not require hospitalization and is a reversible procedure, the stitches are usually removed after a year and a half or two.

Bypass or gastric bypass surgery

In surgeries, this method is most effective because it connects the upper part of the abdomen directly with the small intestine (duodenum), leaving the abdomen to one side, which is not removed, leaving it in place. Yes, but do not eat. Spending more time than that.

This technique is very effective for the following reasons: Stomach size is significantly reduced (reduces satiety), absorption is also reduced and insulin response is reduced. Three basic aspects so that the body does not accumulate, but begins to lose reserves.

Within a year, it is possible to lose up to 75% of the extra weight offered by the patient, although everything depends on the habits that come with the operation (as we said at the beginning of the article: no miracle happens). The operation usually lasts for about three hours and the patient needs to be admitted to the hospital for at least one day for observation.
