The surgeons at Saint Luke's Center for Surgical Weight Loss offer the sleeve gastrectomy procedure, which involves removing a large portion of the stomach. 

The surgeon removes a large portion of the stomach, leaving a smaller banana-shaped stomach with much smaller capacity. This procedure is irreversible.

Weight loss

Sleeve gastrectomy patients lose about 2 to 3 pounds per week and up to 55 percent of their excess weight.


Sleeve gastrectomy is an irreversible procedure where the surgeon removes about 85 percent of the stomach, leaving a smaller stomach with much smaller capacity. Weight loss is generally faster and more pronounced than gastric banding. Overeating can increase the size of the stomach over time.


The stomach can leak, narrow to further restrict its size, and cause hernias.

Saint Luke’s surgeons perform almost all of their procedures laparoscopically. Laparoscopy is a minimally invasive method requiring much smaller incisions than traditional open surgery. This leads to less pain, a shorter hospital stay, and fewer complications.
