Aye, many pateints have no interest in following advice. There is only so much you can do. If only 10% of new diagnosis type 2s are fully compliant then there must be thousands of cured type 2s out there, but this not the case. We all know type2 s that loose lots of weight, exercise and normalise the a1c. Later become ill, have a heart attack etc and the BS raise. The underlying genetic metabolic defect does not resolve.
Again, for diabetics like my late grandmother, would fastidiuos BS control have improved her quality if life? No, I am not convinced. For me with neuropathy and mild retinopathy at 41 yrs old? Yes it does. I need to keep an income and see my kids grow up. The anxiety of not always getting my control right is outweighed by striving to delay the progression of my inevitable complications.
Our hospitals are filled with the results of lifestyle choices. Runners with bad knees, nurses with bad backs, footballers with broken ankles, drunks with assaults, thin women with osteoporotic hip fractures, participants dangerous sports, English hill walkers in the highlands in winter etc. The list is endless just from my own speciality. People have many reasons for not looking after themselves. In general it is a failure of health promotion/education to engage society. You would think it was only poorly controlled diabetics that had bad diets. They just reflect the broad spectrum of diet found in society. One must rant and rave at poor choice diets of diabetics. However, everyone knows what they should eat. No-one is immune to healthy eating information out there. However, the failure of a diabetic to change poor eating habits has to be , in part, a failure of the NHS/government as well. Not every fat person is diabetic, but most types 2s are. Why? Because of hyperinsulinaemia. Why? Its the metabolic syndrome, stupid!
Rant over.
