Hi gramps64,

Yeah - sounds like you've had a couple of close calls. And, sure, likely part of this is your condition - but, there are genetics at work, too. We can't fix our genetics (yet), but we can fix our condition as it relates to weight and condition.

At our age, and if you are obese, simply exercising is not likely to fix your condition - and, could be dangerous, especially given what you have said about arthritis.

I am not a medical professional, but do tend to think logically - I would recommend a serious talk with your PCP where you ask to be immediately put on one of the new diabetes/weight loss meds - you didn't mention your glucose numbers nor your A1C numbers - these need to be tracked and established in the normal range as quickly as possible (again, a non-medical professional opinion). What is you normal weight vs actual?

Once you start heading down in weight, you need to address the arthritis issues - do you need joint replacements? If so, once you have re-established a health weight, find a competent orthopaedic joint replacement surgeon and start the consults.

Finally, as you become smaller and more healthy, begin walking - more and more - as you are doing this consult with a professional and begin a mild exercise regimen.

So, to me the priorities are:
1. Weight
2. Repairs (if needed)
3. Exercise (as reasonable)

Don't give up! Don't become dispirited - this sort of stuff takes time - and EFFORT.
