When a person is overweight or obese, they have options at their disposal to lose weight such as exercising, changing their habits and eating healthy. However, when it comes to severe obesity, diets and other treatments are not effective, and the only long-term way out to maintain weight loss over time is surgery. There are different types of surgical treatments, and each of them carries results and consequences. We explain it, below.


There are three types of interventions:

  • Surgeries that work by reducing the size of the stomach. Restrictive techniques are used and in the long term there is less weight loss. This is the case of the gastric band and the gastric sleeve or tubular gastrectomy. With them, it is common to suffer vomiting or intolerance to certain foods, and sometimes they cause vitamin or mineral deficiencies.
  • Surgeries that act by shortening the intestine: malabsorptive techniques that make food less absorbed. They produce greater weight loss, but can cause more diarrhea and vitamin or mineral deficiencies. Among the most prominent we find the Biliopancreatic diversion with duodenal switch.
  • Surgeries that act on the size of the stomach and that shorten the intestine: mixed techniques such as gastric bypass. It offers good weight loss, as well as fewer complications when it comes to nutritional deficits.
  • Non-surgical endoscopic treatments: it is worth mentioning the treatments that consist of the introduction of a tube to the stomach in order to reduce its size, such as the intragastric balloon or the POSE. They are restrictive procedures and are temporary solutions. For example, the balloon is removed after 6 months.

What should be clear and as we always recommend in Laparoscopic Weight Loss Surgery by Bariatric Surgery Specialist in Vadodara, is that a specialized surgeon must be in charge of analyzing which is the most appropriate technique for each patient. To do this, you should not only look at your weight, but also your general condition and you’re eating habits, among other aspects.



There are many reasons that can lead a person to be overweight, such as an inadequate diet or a sedentary lifestyle, although there are also many other factors that influence. If your body has changed and you think you may be overweight or obese, the first step is to find out if this is the case. For this, the Body Mass Index (BMI) is normally used as the main indicator to measure overweight and obesity in adults.


To calculate the Body Mass Index, you have to perform a simple mathematical operation that consists of dividing the weight (kg) by the height squared (in meters). From the result obtained, the data indicates whether your weight is healthy:

Below 18.5: insufficient weight.

Between 18.5 and 24.9: normal weight.

Between 25 and 26.9: overweight grade I.

Between 27 and 29.9: grade II overweight.

Between 30 and 34.9: type I obesity.

Between 35 and 39.9: type II obesity.

Between 40 and 49.9: type III or morbid obesity.

Over 50: type IV or extreme obesity.

When that BMI limit is exceeded, which already indicates that we suffer from obesity, beyond the evidence at an aesthetic level, there are another series of symptoms that are characteristic, such as self-esteem problems, difficulty in performing movements, stooping or carrying carry out the most daily activities. There are also trouble breathing, joint pain, chronic tiredness, and trouble sleeping. All this without forgetting that obesity can lead to many serious diseases.

Therefore, in Weight Loss Surgery, we want to emphasize the importance of seeking solutions. In addition to leading a healthy life, there are stomach reduction surgeries, such as gastric sleeve or gastric bypass, which can be of great help for some people who suffer from obesity, and for whom conventional methods do not work when it comes to losing weight.
