In the olden days, like 1900s and in fact up until not so long ago around 70 years ago, if you had type 1 diabetes the sad reality was that you died, starved in a sea of plenty. Without insulin glucose can not get into the cells where it is needed for metabolism/function. You slowly starve and die.
Banting and Best discovered insulin and have saved all type 1 diabetics this.
We are forever indebted to their hard work in achieving a treatment.
We no longer have to have our hands tied behind our backs in terms of saving lives when it comes to type 1 diabetes and I think every doctor and every parent is eternally grateful for this blessing given to us by these two doctors.
