In a very nourishing person, blood sugar levels are managed by two hormones: insulin and glucagon.To appreciate how diabetes happens, let’s take a fast search with the basics of blood sugar regulation. Within a balanced individual, blood sugar degrees are controlled by two hormones: insulin and glucagon.
