Poorly manage your diabetes with morbid obesity.

You’ll go blind, end up with renal failure and require dyalysis, have limb infections that become permanent with ever present open skin ulcers, silent heart attacks, early strokes, and every time you get sepsis or need to be operated the morbid obesity and your slowly failing organs from destroyed microvasculature will both try to k**l you.

Proof is in the pudding, regional and/or demographic plots of life expectancy vs obesity, and morbidity in non-compliant diabetes.
