The most rapid weight loss following a VBG takes place in the first six months. It usually takes between 18 and 24 months after the operation for patients to lose 50% of their excess body weight, which is the measurement used to define success in bariatric surgery. At this point, most patients feel much better physically and psychologically; diabetes, high blood pressure, urinary stress incontinence, and other complications associated with severe obesity have either improved or completely resolved.
The primary drawback of VBG is its relatively high rate of failure in maintaining the patient's weight loss over a five-year period. For this reason, some bariatric surgeons recommend VBGs for patients at the lower end of the severe obesity spectrum—those with BMIs between 35 and 40. The chief advantage of VBGs over malabsorptive types of weight loss surgery is that there is little risk of malnutrition or vitamin deficiencies.
Although bariatric surgeons advise patients to wait for two years after a VBG to have plastic surgery procedures, it is not unusual for patients to require operations to remove excess skin from the upper arms, abdomen, and other parts of the body that had large accumulations of fatty tissue.

Other Information
Vertical banded gastroplasty (VBG), also known as stomach stapling, is a restrictive operation for weight control. Both a band and staples are used to create a small stomach pouch. In the bottom of the pouch is an approximately one-centimeter hole through which the pouch contents can flow into the remainder of the stomach and thence onto the remainder of the gastrointestinal tract.
Stomach stapling is a restrictive technique for managing obesity. The pouch limits the amount of food a patient can eat at one time and slows passage of the food. Stomach stapling is more effective when combined with a malabsorptive technique, in which part of the digestive tract is bypassed, reducing the absorption of calories and nutrients. Combined restrictive and malabsorptive techniques are called gastric bypass techniques, of which Roux-en-Y gastric bypass surgery (RGB) is the most common. In this technique, staples are used to form a pouch that is connected to the small intestine, bypassing the lower stomach, the duodenum, and the first portion of the jejunum.
This type of weight loss surgery is losing favor as more doctors begin using the adjustable gastric band. The newer adjustable band does not require cutting into the stomach and does not use any staple lines, thus making it a much safer alternative.
VBG is known in the medical community as a very serious and dangerous procedure. It has been classified by the AMA as a "severely dangerous" operation.
