Thank you for your question regarding the safety of undergoing a tummy tuck and liposuction while taking diet pills. It's important to be cautious when combining any medications or supplements with surgery, especially when general anesthesia is involved. Diet pills often contain stimulants, appetite suppressants, or other ingredients that can affect your heart rate, blood pressure, and overall metabolism. These substances may increase the risk of complications with anesthesia, including elevated heart rate, high blood pressure, or cardiac issues during surgery. Some diet pills, especially those with stimulant effects, can also interfere with your body’s ability to recover smoothly after surgery. For your safety, it is crucial to disclose all medications, supplements, and diet pills to your plastic surgeon and anesthesiologist prior to surgery. You may be asked to stop taking diet pills for a certain period before your procedure to ensure that your body is stable and that the surgery can be performed with minimal risk. Your surgeon will provide specific guidelines based on the type of diet pills you’re taking and your overall health. It’s always better to err on the side of caution to ensure a safe and smooth surgical experience. Sincerely, Dr. Katzen
