INTRA GASTRIC BALLOON (IGB)
It is indicated for temporary weight loss in those who are unfit for bariatric surgery. It is a bridging procedure before bariatric surgery to induce weight loss, so as to make these individuals fit for surgery. It is also indicated for mild obesity. Intra gastric balloon is introduced by performing upper gastrointestinal endoscopy under sedation. Obalon balloon can be swallowed. But to check whether you are suitable for ballon procedure, you need to undergo upper gastrointestinal endoscopy before swallowing balloon.
Once introduced, it occupies part of the stomach and creates sense of fullness. It reduces the amount of food taken each time. So IGB acts mainly by mechanical restriction. Its effect, on hormones controlling body fat stores, is minimal. So body fat set point is not altered much. IGB can be kept either for 6 months (Eg – LexBal, Orbera, Obalon) or 1 year (Spatz 3).
It is simple, very safe and doesn’t require admission. It doesn’t require any cuts on the abdomen. It is a good choice for weight loss in individuals with BMI < 30 kg/m2. It is considered as an adjuvant to healthy diet, exercise and behavioral modification in these individuals. In these, since weight burden is not much, fat set point can come down to some extent by healthy diet and exercise. And IGB helps to increase weight loss. After balloon removal, these individuals should stick on to healthy diet and exercise in order to keep fat set point nearer to normal limits.
After balloon removal, if bariatric surgery is not performed, all the lost weight will be regained in most of the individuals, because of the effect of hormones controlling fat set point. So weight loss after IGB is temporary especially when it is performed in individuals with BMI ≥ 30 kg/m2. Those who regain weight after IGB, need bariatric surgery for weight loss.
