Laparoscopic Sleeve Gastrectomy, a type of stomach reduction operation, is purely a restrictive type of weight loss surgery which involves surgery on the stomach only.
About 75% of stomach is excised vertically with the help of staplers thereby reducing the storage capacity of stomach from 1.5 litres to 100ml.Vertical sleeve gastrectomy is one of the newer types of bariatric surgery

How Sleeve Gastrectomy works:

• Reduced hunger –Your stomach is responsible for secreting the hunger-causing hormone called ghrelin. Since such a large part of the stomach is removed following gastric sleeve surgery, your feelings of hunger may decrease, increasing the likelihood of sustained weight loss.
• Hormonal changes-hormonal changes that occurs in our body following surgery  changes the taste for sweet things, reduces the craving for sugar and cure of obesity related diseases like diabetes and hypertension.
• Reduced storage- due to removal of about 80% of the stomach, the storage capacity is highly reduced and as a result you  tend to feel fuller after taking a small amount of meal.

Positives of Sleeve Gastrectomy:

•  Average weight loss is 60% of excess of body weight.
• Gastric sleeve surgery also helps in getting rid of obesity related heath problems:
Diabetes – 80% have their diabetes cured and 90% have improvement in diabetes. However, patient selection    criteria and type of surgery performed is very essential for optimal results.
High Blood Pressure (hypertension) – 68%  patients get their high blood pressure cured permanently  and 95% have improvement following surgery.
Obstructive Sleep Apnea – 80% have their obstructive sleep apnea completely resolved and 90% showed marked improvement following surgery
•  Patients usually do not require long term  vitamin or mineral supplements.
• Low maintenance surgery as very few blood tests and follow up are necessary.

For patients with mild reflux, gastric sleeve may still be an option.

Appetite does tend to return after approximately one year but it will be a more normal healthy hunger feeling.
