The inflation of the gastric band usually takes place at the end of the first month. 
  
It should be known that the inflation is not obligatory: if the weight loss is suitable (2 to 4 kgs), and if the feeling of satiety is good, the band can be tightened at the end of 2 or 3 months, or later.

When your band is tightened, the feeling of satiety must occur quickly, but the risk of vomiting increases.
Continue to select your food and eliminate all the mets with high caloric value.
You will be probably obliged to grope at the beginning on various food, their volume, their size.

Ideally, you must decide when to make insuflate your gastric band.

If the weight loss (2 to 4 kgs per month) is insufficient, if the feeling of satiety decreases. In short, if the gastroplasty appears definitely less effective to you, it is time to make tighten your band.
Contact quickly your surgeon.

On the other hand, if the food does not pass well, if vomiting appears, if the weight loss is higher than 4 kgs per month, also contact your surgeon.
A radiography of the gastric pouch is necessary, and possibly the surgeon will make the decision to loosen the band.

The number and the importance of inflations are very variable. Some patients do not make tighten the band the first year and lose 2 to 4 kgs per month. For some others, it is necessary to tighten the band 3 or 4 times to obtain a good result.

Do not forget that maximum weight loss is obtained in the first two years after the procedure.
