The correct answer is, my friend, that your friend's hypoglycaemia came about as a result of "a complication caused by treatment". He either took too much insulin, or oral medication, dependent on which type of diabetes he has; he didn't take a sufficient amount of carbohydrates; or he exercised without making allowance for this by either adjusting his insulin or not eating extra carbohydrate to counter the insulin that he had present within his bloodstream.
Some diabetics, their blood sugar swings wildly out of control. Too high (hyper) then too low (hypo). I think this happens in type 1s more than type 2s.
I think some diabetics, their bodies lose the ability to regulate blood sugar automatically. I would say it's a symptom, not a complication.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
