In a very healthy and balanced particular person, blood sugar degrees are managed by two hormones: insulin and glucagon.To understand how diabetes occurs, let’s acquire a fast take a look for the principles of blood sugar regulation. In the wholesome man or woman, blood sugar ranges are controlled by two hormones: insulin and glucagon.
