After attending a seminar and listening to Dr. Ahmad, I decided to have a gastric bypass. For the first time, I heard someone tell me that at this stage, it was indeed impossible for me to loose weight through diet, and that I needed an intervention. I could stop feeling like a failure, and do something that could and would work. I did my homework and knew that Dr. Ahamad was the best in this field; he even convinced my oldest daughter, and let me tell you, that is quite a feat. I am very afraid of anything surgical, and I had more that my share of anxiety. But the kindness of Drs Ahamad and Argawala and the entire staff helped me through. I had the surgery 1 month ago today, and after weighing myself yesterday, I did a little dance around my house. I have lost 25 lbs in 4 weeks *, and I have not been hungry at all. I have followed the diet, followed the rules, and I have had no problems, it has been absolutely great. Any discomfort in the beginning was so worth it. I definitely would have had a short life if I stayed obese and the list of life-threatening diseases would have gotten longer; now, I feel reborn. I look forward to my new life. The best is yet to come. My daughters are thrilled and amazed at my progress. and NEVER NEVER would I have done this if I had not met Dr. Ahmad and his team. To his wife who visited me in the hospital and to the wonderful staff on the bariatric hospital floor, to Lisa in Nutrition, thank you a million times. – Odette L – vitals.com review



My experience with Dr. Ahmad was that he was caring and interested in my personal goals both before & after surgery. The entire experience with the gastric by-pass proved to be exceptionally beyond my expectations. I lost 100lbs * , no longer needed any medications for the various medical * issues & I am healthier then I have ever been. I highly recommend Dr. Ahmad and his team for bariatric surgery He is the best in this field!! – Diane S.P – vitals.com review



March 20,2013 was the first day of the rest of my life began as a newer me. Thanks to Dr. Ahmad and his staff I have now lost 105 lbs 7 months * . Looking at the pictures of me before surgery were really surprising to me I knew I was heavy at 300 lbs but I never thought I looked the part. As the saying goes pictures don’t lie and wow I’m really shocked looking at the differences so far. If you’re on the fence about the surgery “get off and do it” the procedure was uneventful and the new style of living is grand. – Charles W.

Five years ago I was blessed with the option to have lap band surgery! 167 pounds lost * and I wouldn’t change it for anything feeling great! To an amazing doctor and staff you are all one of a kind! – Kim D.



While driving in the car today Jake and I had a great conversation…Jake – “Daddy I saw an old picture of you on dad’s phone and your arm was really big” Me – “Just my arm Jake?” Jake – “no all of you, you were fat” Me – “I was, so what am I now Jake?” Jake – “you are skinny” Me – “is that how you see me now?” Jake – Yes!” That’s because you ate too much right Daddy? Me – “yes Jake you are right, Do you remember Daddy being that fat?” Jake – “no I don’t ” Jake – “so all that had to do is put 5 holes in you and let out all the air out and now you are skinny?” Me – “Yes Jake it was just that easy” (I wish it was)…out of the mouths of babes. Right after my surgery my doctor told me “Isn’t it great that your kids will only remember you as being skinny? I didn’t believe my doctor at that time, but I guess I was wrong. I love my “Little Men” and today they made it perfectly clear to me that I did the right thing. Thank you doc! I was born in Mather Hospital twice…The first time on October 26, 1967 and then once again on June 04, 2012. I love myself and even more I love my family. – John C.   *
