My brother is diabetic, I seek your suggestions?

Anurag K asked:

He is 27 yrs old, was very athletic and fit. Diabetes was diagonised in him six months ago,but he might have been diabetic for some years now.for some years he had been suffering from occasional acute stomachache. His sugar level always remains between 140-200 before or after fast, despite medicines. Doctor recently advised him insulin. We think dependence on insulin is risky and costly, so we are avoiding insuling and instead he is following tight yoga,exercise and diet schedule, to no avail. He is getting weaker day by day. Kindly provide your opinions. Does it mean he will not be able to live a normal life or his days are numbered?

We are doubtful if he has Type I or Type II. Doctors have never specified. He has undergone most of the tests recommended for such patients and eveything has been found normal.But we guess his case is of Type I. How can it be cleary determined? his Hb1Ac report was 197 mgdl. Isn’t is possible that his is only Type II? We’re worried and confused.
Is is possible his is only Type II? If it is so/not so, does taking insuling once makes one dependent on it for lifetime? Or should he try to take is for some time then try to manage without it once he becomes normally fit? It is possible?

Why don’t docs suggedst him to take vitamin-mineral supplements in the form of medicines to improve his health? He has always been taking normal food and exercises/yoga(as advised by docs now) for long as a routine. So,I wonder how the same can now control his sugar levels. He is getting weaker day by day, despite taking medicines to control sugar.

Could I have pre-diabetes?

I have been having most every symptom of diabetes. Except for the rapid weight loss.
Recently I had checked my blood sugar after about an hour of eating a piece of candy and chocolate milk. I was babysitting a kid with diabetes so I figured why not check mine. it was 135. Which I thought was good because he told me it was.
Lately I have been having more symptoms and so I was looking around here and the internet and I saw someone saying he was diagnosed with pre-diabetes because his was 130.
