The gastroplasty is a relatively simple procedure, with a 2 or 3 days hospitalization.

The gastroplasty causes loss weight from 2 to 4 kgs per month.
The maximum of weight loss is obtained the first 2 years. It is rather advised for BMI lower than 45. According to the scientific data, the gastroplasty makes lose - on average - more half of weight excess after 2 years.

 Denutrition and vitamin deficiencies are rare.
No oral supplementation is necessary. A biological assessment after a weight loss from 25 to 30 kgs is carried out. Sometimes it shows small vitamin deficits which are easily made up by oral way.

 This method is completely reversible. 
the band can be easily loosened, it can be withdrawn with a new coelioscopy.

 Nibbling and ingestion of sodas or icecreams represent the principal factor of failure of the method.
They must be completely proscribed ; if not, you will lose little or not.

Alimentary comfort is decreased.
If you eat too much, too quickly, of too large pieces, you will vomit.

 Food practices must be completely modified. 
3 meals and possibly 2 collations.

 A regular follow-up by a disciplinary multi team is obligatory.
The gauge of the band must be modified, usually 2 times the first year. A radiologic control of the gastroplasty is necessary - at least - once per year.
