Hello.Welcome to HCM forum.May be oral hypoglycemic drugs are loosing effect on you.Normally 8 to 10 years after starting,oral hypoglycemic drugs loose their effect and patient has to be put on inj. Insulin
.This results from total destruction of beta cells of pancreas
which are responsible for production of insulin.don't take any medicine yourself and consult your physician or diabetologist
for the proper treatment.Thanks and good luck.
