b) Diabetes mellitus – deficiency of insulin hormone


When high quantities of glucose enter the blood stream, the excess glucose is converted into insoluble glycogen and is stored in liver and muscles for future use. All these processes are controlled by the hormones, insulin and glucagon. If insulin is not produced in sufficient quantity, excess of sugar cannot be stored in the liver and cannot be utilized. As a result, sugar gets accumulated in the blood and is subsequently expelled through the urine. This results in diabetes mellitus.
