The best treatment option broadly depends upon your weight loss goals as each procedure has got its own limitations of producing the sustainable results.
Published scientific papers report that non-surgical methods rarely resolve severe obesity because they fail to help people maintain weight loss. In fact, more than 95% of people regain the weight they lose within a few years after treatment.
If your target for weight loss is 5-8 kg, it can be achieved with diet, exercise, and behavior modifications or medical weight loss program.
If you wish to achieve a weight loss of 10-15 kg, then intragastric ballooning can be a good option. However, along with that, dietary and behavior modifications are a must to achieve excellent long-term results.
Suppose your target for weight loss is more than 20 kg. In that case, bariatric surgery is the best available option for long-term successful weight loss.
