My moment of truth was finding out my mother was diagnosed with a disintegrating hip joint at 54.
I already have Type II Diabetes, high blood pressure, high cholesterol, severe achilles tendonitis, acid reflux and bone spurs in my neck. I looked up in a health journal what the best prevention of hip problems.....lose weight.

That never works for me...
So, instead of getting old and rickety and bed-ridden before my time, I decided to look into getting WLS. Which is scarier? Dying young or having major surgery? I decided dying young is scarier. Plus, I had quite a few successful WLS examples around me, so it makes sense to me.
Hope your decision making goes smoothly!
