Hello and Welcome.
I'm 5'7 and weighed 221 lb when I decided to have plication. Personally, it truly is a decision you must make for yourself because only you will have the experience and outcome. But for me personally, it was the best decision I ever made. Going through not just the surgery, but the pre op diet, the post op liquid phase, to soft food phase, to regular food did something for me psychologically. It cleansed my palatte of all the junk I had been craving and it really allowed me the positive opportunity to be in control of what I eat. I lost 15 lbs with my surgery center's required pre op diet and weighed in at 206 the day of my procedure, last month, July 20th, and today, 1 month and 5 days later I have lost 17 lbs post plication. That is a total of 32 lbs that I no longer carry. I feel so much better, I am more limber, I can bend better and reach over and tie my shoe without turning blue in the face! All things I took for granted before my weight gain.
I hope this helps. The main thing to do is research the facility you are thinking of having your procedure at. Research the Doctor. Make sure s/he is qualified and experienced. Best of luck and keep in touch.
