These are the operations that can be done to lose weight

Needless to say, bariatric surgeries or surgeries to treat obesity are operations that always have to be recommended by specialized medical personnel, they are not operations that are done on a whim or to take a shortcut to lose weight.

}There are several methods or operations that can be done to lose weight, today we will give a review of the main ones: what they are, what they are and how they help to lose weight.

These operations are not the panacea and work for life, you need to adopt a healthy lifestyle so that the lost kilos do not return to win over the years.

Yes, slimming operations are effective, but they also have risks and require a commitment to change lifestyle, if not, they are useless. Let’s see one by one the different operations:

Intragastric balloon

It consists of introducing a saline ball inside the stomach with the intention of halving the volume of it. By decreasing the gastric volume, the sensation of satiety appears before, thus decreasing the daily intake of food.

The operation is quite safe, does not require hospitalization, anesthesia or usually has complications. The deflated balloon is introduced by endoscopy and, once inside the stomach, if it is inflated with saline and the valve is sealed.

Although there is already a more advanced method: the ingasible intragastric balloon. It would be enough to swallow a capsule attached to a thread. Once in the stomach the balloon would swell. A much less aggressive method.

The balloon is left in the stomach for 6-8 months and usually loses an average of one kilo per week, although it depends a lot on each person.

In this time, in addition to losing weight because we eat less, the key is to reeducate the eating habits so that when the ball is removed, we are able to maintain the weight.

Gastric band

An inflatable band is placed around the upper part of the stomach, creating a kind of small stomach. Again, the goal of the intervention is to decrease the volume of the stomach so that the feeling of satiety appears earlier. In addition, the band prevents the stomach from expanding and can receive more food.

The passage of food from this first stomach, smaller, to the rest of the stomach, will be done little by little by a small hole, whose diameter is regulated by the swelling of the band with saline.

The first swelling of the band is usually done on the sixth week, afterwards, it only swells if the patient stagnates in the loss of weight.

This operation does not require hospitalization or anesthesia, but it is somewhat more invasive than the intragastric balloon, since it requires laparoscopy (small incisions in the abdomen where the band is inserted and placed) and some points to fix the band. to the stomach.

Gastric sleeve

Here we already enter more invasive surgery and, although it is done by laparoscopy, the size of the stomach is reduced by eliminating part of it (gastrectomy), in 75-80%. The stomach is cut vertically and stapled, forming a “sleeve” the size of a banana.

Here we already enter more invasive surgery and, although it is done by laparoscopy, the size of the stomach is reduced by eliminating part of it (gastrectomy), in 75-80%. The stomach is cut vertically and stapled, forming a “sleeve” the size of a banana.

This operation lasts between one and three hours and does require hospitalization, and must remain in between two and three days. The stomach retains all its functions, it has simply reduced its volume considerably, so the feeling of satiety will appear before.

The weight loss with this operation is greater than that achieved with the gastric band, although less than what would be achieved with a gastric bypass, but the risks and side effects are minor, since here we are conserving part of the stomach, Unlike what is done with the gastric bypass, where the stomach no longer receives food and it goes directly to the intestine.

Gastric plication
This operation is similar to the previous one, in contrast to the fact that there is no gastrectomy but gastroplasty, by folding the stomach on itself ** inward, reducing the volume of the stomach but conserving it in its entirety.

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

Bypass or gastric bypass surgery

Within the surgeries, this method is one of the most effective, since it directly joins the upper portion of the stomach with the small intestine (duodenum), leaving aside the stomach, which is not removed, left in place, but the food will no longer go through it.

This technique is so effective for the following reasons: the size of the stomach is considerably reduced (satiety decreases), absorption is also reduced and the insulin response is reduced. Three fundamental aspects so that the body does not accumulate, but begins to lose reserves.

In a matter of one year you can get to lose 75% of the excess weight that the patient presents, although everything depends on the habits that accompany the operation (as we said at the beginning of the article: there are no miracles).

The operation usually lasts about three hours and requires hospitalization at least one day for patient observation.


We can consider this operation an aesthetic operation, since it does not affect the digestive processes, but it directly removes excess fat and skin from the abdomen, which is usually the part where it accumulates the most.

This operation requires general anesthesia, and there is no laparoscopy, it is a more invasive method where the skin of the abdomen is released with a scalpel, removing the excess of fat and skin, even the abdominal muscles are reinforced with sutures if they are very flaccid

The operation usually requires general anesthesia, lasts about 2-4 hours and after the operation you have to wear a girdle for greater support of the area. Here, although in a minimal way, there are scars and it takes a while for the abdominal shape to be homogeneous.


This can also be considered an aesthetic operation. It is the best known when it comes to removing fat from the middle, but it does not help if after a liposuction we continue with bad eating habits, since nothing is involved in the digestive system.

It basically consists of extracting fat through a syringe that sucks it. Here the problem is that before a significant reduction of fat, skin will be left over and aesthetically it does not look good, so it will be necessary to do another operation afterwards to reduce that excess of skin.

It does not require hospitalization and anesthesia is local, so it is a few hours we can remove a few kilos of fat.

Weight reduction operations are not miraculous

Surely you will hear testimonies from people who speak wonders of operations to reduce weight, but not everything is so beautiful. Keep in mind that an operation “always” involves a risk, especially if you have general anesthesia.

And it’s not about operating and continuing with our lives as before. These operations also have post-operative diets and specific dietary recommendations.

You also have to take into account that you have to meet a series of requirements for some operations, not worth losing those extra kilos, this type of operations are usually done when obesity already poses a big risk to the patient’s health.

Of course, we always recommend changing life habits to lose weight, although we also know that there are difficult cases that require surgery, but they are usually the least and also require great commitment for the surgery to be effective over time.
