Due to the decreased pancreatic insulin secretion, glucose is not utilized by the body. the replacement of insulin is the treatment for this type. Type 1 diabetes is seen in hereditary cases. if once it diagnosed life long therapy should be taken.

2.Type 2 diabetes: it is usually seen in adults. in this type, there is a normal insulin production but the tissues are resistant. the deficient uptake of insulin by the tissues leads to an increased level of glucose in the blood. type 2 usually occurs in obese persons. the oral hypoglycemic agents are used as treatment. it can be controlled effectively by medications, exercise, diet and other lifestyle modifications.
