I had the Gastric bypass surgery about 7 years ago. I lost about 50 pounds because of surgery but since then I have regained about 20 lbs. I am now about 55 lbs over weight. and have some questions for anyone who can help me with them. Is it ok for Gastric Bypass patients to do a cleanse? My husband has used the Garcinia Cambogia with a Cleanse and has lost a lot of weight with it. Is it possible for GBP patients to use??
