My background is of a very fit, 68 year old, non-smoking, sports playing, running male. I had a heart attack in 2016 brought on by an unknown birth defect. Since then, due to medication, I've not been able to train as hard as I'd been used to however, I've maintained a very fit and healthy lifestyle but developed into a Pre, Type2 Diabetes condition. 4 months ago my 'score' went up to 48 on the Diabetes scale and I refused medication. Since then I have trained (run/walk/ex) or played golf every day, followed a low blood sugar diet and lost 11 kgs and weigh 72 Kgs (Height 1.74m). My score last week dropped by just point and I remain a 'Type 2 Diabetic'. The Surgery Nurse says we'll check it again in 3 months but I don't have any more weight to lose even though I'm happy to maintain the diet. I don't have any confidence in the surgery; what should I do?
