Bariatric revision surgery is a surgical procedure performed to modify or correct a previous weight loss surgery that has either failed to produce the desired weight loss or has led to complications. Revisional surgery is a complex procedure that requires careful evaluation and planning by a multidisciplinary team, including bariatric surgeons, nutritionists, and psychologists. A patient should decide to undergo revisional surgery after thorough discussions with healthcare providers, weighing the potential risks and benefits. Additionally, patients may need to undergo preoperative evaluations to assess their current health status and determine the most appropriate course of action.
