Speaking for myself I was more afraid of having to deal with the future damage to my body due to the ravages of diabeties. I was beginning to experience nerve pain, and sleep issues and had been on insulin, shooting myself in the stomach 5-6 times a day.
I was sick and tired of managing an illness.
After 2 years with the band, 52 pounds lighter and off most of my meds I can honestly say I have no regrets.
I was overweight, now I am not. Everything from pre-surgery to now, for me, has been totally worth it.
I have had some challenges along the way, but the truth is, for me, it was more of a challenge being overweight than to learn how to become a thinner healthy person. The surgery changed my life for the better and I am so glad I went for it.
For me, the surgery was not really all that big of a deal, the hair loss was really not all that big of a deal. The immediate results for me were off insulin since the day of my surgery and down about six sizes after 14 months. My knees don't hurt, my skin is better. I don't think about food all the time like I used too, and make the effort to have the proper foods on hand and eat the lap-band way most of the time.
Good luck to you in whatever you decide.
