gastric-bypass
Gastric Bypass

Gastric bypass is a popular weight-loss surgery designed to help people lose weight by significantly reducing the size of the stomach. This procedure is often recommended for people struggling with severe obesity who haven’t achieved lasting results through diet, exercise, or weight loss medication. By limiting food intake and nutrient absorption, gastric bypass supports effective, long-term weight loss and may improve overall health.

gastric-sleeve
Gastric Sleeve

Gastric sleeve surgery is a proven weight-loss surgery designed to help people with obesity achieve lasting results when diet, exercise, or weight loss medication have not been successful. The surgery removes a large portion of the stomach, creating a narrow, sleeve-shaped pouch that limits food intake and reduces hunger by lowering levels of appetite-regulating hormones. This dual effect supports sustainable weight loss and may improve overall health.

revisional-surgery
Revisional Surgery

Revisional weight-loss surgery is a corrective procedure performed to address complications or adjust a previous weight-loss surgery. It’s often recommended when the initial weight-loss surgery does not deliver the expected results, complications arise, or additional treatment is needed to enhance long-term success. Revisional surgery helps optimize weight loss outcomes and improve overall health after the original procedure.

gastric-band-repair
Gastric Band Repair or Removal

Gastric band repair or removal may be necessary if complications occur, such as band slippage, erosion, or insufficient weight loss. In some cases, the gastric band can be adjusted to improve results, while in others, removal of the gastric band is recommended. Many people choose to follow up with another weight loss surgery—like gastric sleeve surgery or gastric bypass—to achieve more effective, long-term weight loss results.
