Primary Weight loss Surgery

This is the most common minimally invasive surgical weight loss procedure which has been well established as a safe and effective option for long term weight loss. The gastric sleeve reduces your stomach volume to help you feel satisfied with smaller portions. Most patients see significant weight loss within the first year, potentially resulting in resolution of diabetes, high blood pressure, and sleep apnea.

If you struggle with severe obesity or conditions like acid reflux or Type 2 diabetes, gastric bypass may be an option for you. This procedure reduces your stomach size and reroutes the intestinal tract to help you feel full quickly and absorb fewer calories. The gastric bypass has more complications as compared to Sleeve Gastrectomy and the SADI but may be an option in selected patients.

For those suffering severe metabolic conditions such as insulin dependent diabetes or high cholesterol despite medical therapy, the SADI procedure may be the best option for you. This combines a gastric sleeve with an intestinal bypass. This procedure helps with weight loss, better blood sugar control, hyperlipidemia, hypercholesterolemia and sleep apnea. In addition, it is the preferred revision option in patients with a previous sleeve gastrectomy.
