Final answer:
Type 2 Diabetes is non-insulin dependent and the most common form, often linked to insulin resistance, while Type 1 Diabetes requires insulin injections due to an autoimmune destruction of beta cells.
Step-by-step explanation:
Non-insulin-dependent diabetes mellitus is also called Type 2 Diabetes, and insulin-dependent diabetes mellitus is called Type 1 Diabetes. Type 1 diabetes is a chronic autoimmune disorder in which the immune system attacks the insulin-secreting beta cells of the pancreas, leading to a lack of insulin production. People with this form of diabetes require synthetic insulin injections to manage their blood glucose levels.
On the other hand, Type 2 diabetes is the most common form of diabetes, affecting about 90% of those with the condition. It often develops due to insulin resistance, where cells of the body become less responsive to insulin, and may also involve a reduction in insulin secretion. This type of diabetes is a multifactorial disorder with both genetic and environmental factors contributing to its development. Management includes diet, exercise, medications, and sometimes insulin therapy.
