Sleeve Gastrectomy: What to Know about It?

Sleeve gastrectomy is a restrictive type of weight loss surgery. An estimated of 85% of the stomach is being removed which leaves a sleeve shaped stomach that has a capacity of about 60- 150-cc, depending on the surgeon that performed the surgery. Unlike with the other types of bariatric surgery, for this one, the outlet valve and the nerves are intact. The stomach however is reduced in size; all its functions are preserved. This surgery is also not reversible.


Restrictions of the Surgery

Since the stomach keeps its normal functions, there are some restrictions when it comes to the food that the patient needs to consumer after the surgery. The amount of food that should be eaten is also significantly reduced.

Patients often consider this as a great advantage because the removal of the stomach results in the virtual elimination of hormones that are produced within the stomach that stimulate hunger.


The Advantage

One of the best advantages of sleeve gastrectomy is that it does not involve the need to bypass the intestinal tract. This means that patients need not suffer any complications that often arise in intestinal bypass like anemia, intestinal obstruction vitamin deficiency, protein deficiency, and osteoporosis.

This is the best type of surgery for those patients that are already suffering from Crohn’s disease anemia and other conditions that may place them at a very high risk of surgery that involves intestinal bypass.

Moreover, it is among the few forms of surgery for weight loss that could be done laparoscopically in patients that are overweight.



If there is a disadvantage in this type of surgery is that it may not always result in the kind of weight loss that people are wishing for and in long term, could result to weight gain. This is actually true in any form of restrictive weight loss surgery.

Since the procedure needs stapling of the stomach, this means that patients may run the risk of any leakage and some complications that are directly related from stapling. Aside from this, just like with other types of surgery, patients could have the risk of other complications like small bowel obstruction postoperative bleeding, pneumonia, or death.

However, the risk of experiencing these complications is very small and would vary from about 0.5 and 1%. Given this, the risk of death that may result from the surgery at about 0.25% is very small. Generally, this type of surgery is best for people who are extremely overweight or patients whose medical condition will rule out the other forms of weight loss surgeries.

If you have plans of having this type of surgery, be sure to talk with your doctor first in order to find out if this surgery is the best type for you considering your needs.
