Insulin replacement therapy is always used in?

Insulin replacement therapy (IRT) is always used in the treatment of type 1 diabetes. In this condition, the body's immune system attacks and destroys the insulin-producing islet cells in the pancreas, leading to an inability to produce insulin. Because people with type 1 diabetes cannot produce their own insulin, IRT is essential for controlling their blood sugar levels and preventing serious complications, such as diabetic ketoacidosis (DKA) and long-term organ damage.

For individuals with type 2 diabetes, IRT may be necessary in certain circumstances, such as when lifestyle changes and oral medications are no longer effective in managing blood sugar levels. Unlike type 1 diabetes, where IRT is required from the onset, type 2 diabetes is often initially managed through lifestyle modifications and medications that help the body use insulin more effectively or increase insulin secretion. However, as the condition progresses or complications develop, IRT may become necessary to provide adequate blood sugar control.
