Welcome to healthcare Magic!
is a steroid called prednisolone
. Steroids have the side effect of causing hyperglycemia
that is a diabetes
like state. This is a temporary state when one is on short courses steroid treatment.
The effect is short lived and there is mostly full recovery of the sugar control mechanisms within a week.
So you have already recovered from it and need not worry further in that regard.
The values you have provided of the follow up are also normal.
I hope the advise would be informative and useful for you.
