What is one key difference between Type 1 and Type 2 diabetes regarding insulin?

Type 1 diabetes is characterized by an absolute deficiency of insulin due to the autoimmune destruction of insulin-producing beta cells in the pancreas. As a result, individuals with Type 1 diabetes do not produce sufficient insulin and must rely on external sources, such as insulin injections or infusions, to control their blood glucose levels. This condition typically manifests early in life, and because the body cannot produce insulin, the use of insulin therapy is essential for survival and managing the disease effectively.

In contrast, Type 2 diabetes involves insulin resistance, meaning the body still produces insulin, but the cells do not respond effectively to it. This can lead to elevated blood sugar levels. While some individuals with Type 2 diabetes may eventually require insulin therapy, many can manage their condition with lifestyle changes, including diet and exercise, especially in the earlier stages of the disease.

The distinctions between Type 1 and Type 2 diabetes are vital for treatment approaches and understanding patient management.
