Question

Why does a diabetic patient take insulin injection ?

Answer 1

insulin is a hormone secreted by pancreas , when our body stops the production of insulin which helps us to use sugar (glucose) for energy production and to store for future use.
insulin helps to maintain the sugar level in our body hence it is necessary for a diabetic patients to take insulin

Answer 2

♤ Insulin plays an important role in sugar metabolism. In some patients of diabetes , insulin secretion is reduced.

♤ Insulin injection is given to such patients to compensate for reduced insulin secretion in the body.

♤ Such cases of diabetes are called Insulin Dependent Diabetes Mellitus ( IDDM ).
