GASTRIC SLEEVE SURGERY
This is the ‘gold-standard’ treatment for obesity in the world. With this operation, the surgeon removes part of the stomach and makes a tube or ‘sleeve’ out of the rest of the stomach.
The surgery takes about two hours since the time you enter the OR until the you time you get out. The gastric sleeve by its self takes from 40 to 60 minutes.
Your surgeon will make a few small cuts in your belly and insert a laparoscope, an instrument with a tiny camera that sends pictures to a monitor. The surgeon will then insert other medical instruments through the additional cuts and remove 3/4 of your stomach. Finally, the surgeon will reinsert the omentum.
The new, banana-shaped stomach is much smaller than the original, it is only about 20% of what your original size was. By taking away the 80% of your stomach, we also get rid of the cells that produce Ghrelin, a hormone that regulates appetite.
After the procedure, a person will eat less, feel full sooner, and be less hungry. Unlike gastric bypass, a gastric sleeve operation only changes the stomach.
HOW DOES GASTRIC SLEEVE SURGERY CAUSE WEIGHT LOSS?
Gastric sleeve surgery is a restrictive procedure. It significantly reduces the size of your stomach and limits the amount of food that can be eaten at one time. After eating a small amount of food, you will feel full very quickly and continue to feel full for several hours. The food intake restriction causes the weight loss.
Sleeve gastrectomy may also cause a reduction in appetite. In addition to reducing the size of the stomach, a gastric sleeve surgery may also reduce the amount of the “hunger hormone” produced by the stomach which also contributes to greater weight loss after the procedure.
WHAT ARE THE BENEFITS OF THE GASTRIC SLEEVE SURGERY?
Depending on the weight they had before the operation, patients can expect to lose between 40% to 70% of their excess body weight in the first year after surgery.
Many obesity-related conditions or illnesses improve or are resolved after gastric sleeve surgery. Diabetes, hypertension, obstructive sleep apnea and abnormal cholesterol levels are improved or cured in more than 75% of patients. Though long-term studies are not yet available, the weight loss that occurs after gastric sleeve surgery results in dramatic improvement in these medical conditions in the first year after surgery.
STEP BY STEP
Thinking about undergoing a gastric sleeve procedure can generate anxiety and nervousness, as well as excitement and enthusiasm. Traveling to a distant place to perform any surgical procedure can generate fear making the decision even more difficult to take. Here we explain step by step from the first day to the last of what this experience is about and provide peace of mind.
