Hi there! I had the inverted gastric sleeve by Dr. Kim almost 4 years ago, and have had NO regrets! It has been the most loving, selfless thing I have ever done for myself. In these 4 years, I have only had a 20 lb regain....I accept responsibility for that, and know that I still have the tool! I would do it again 100 times over.... good luck to you, and i hope you make the best decision for yourself. Here is a pic of my before/after, having lost 132 lbs!
