Gastric sleeve surgery removes about 80% of the stomach, which helps reduce the amount of food
that a person can eat in a single meal.
This assists patients in losing weight because they consume less food.
The surgery also reduces the hunger hormone ghrelin that originates in the stomach, so people feel satiated easier.

With gastric sleeve surgery patients suffering from extreme and chronic obesity reduce can reduce
about 60% of their excess weight, on average.

About the procedure

The surgery is performed laparoscopically, using small incisions in the skin, minimizing scars.
This minimally-invasive method helps prevent complications such as infection or an incisional hernia (bulge)
from a poorly healed surgical scar.

Possible complications after surgery include pain, dizziness, vomiting, bleeding, leakage from the stomach,
 infection, blood clots, and difficulty swallowing.

Gastric sleeve surgery advantages

In addition to helping reduce obesity-related health problems, the gastric sleeve:

• Quickens recovery and return to daily activity
• Lowers vitamin deficiencies in patients compared to other bariatric procedures
• Enables patients to consume a rich variety of foods after surgery

Gastric sleeve surgery disadvantages

• Weight reduction and maintenance are lower than in other bariatric surgeries.
• Consumption of high-calorie beverages can prevent weight loss.
• Surgery carries an increased risk compared to lap banding surgery.
