In which type of diabetes does the body develop insulin resistance?

In Type 2 diabetes mellitus, the body's cells become resistant to insulin, which is a hormone that facilitates the uptake of glucose from the bloodstream into the cells for energy. This resistance means that even though insulin may be present, the cells do not respond to it effectively, leading to higher levels of glucose in the blood.

Over time, the pancreas attempts to compensate for this resistance by producing more insulin, but it may eventually struggle to keep up with the demand. This condition is often associated with obesity, physical inactivity, and a family history of diabetes, making lifestyle factors strongly influential.

In contrast, Type 1 diabetes is characterized by an autoimmune destruction of insulin-producing beta cells in the pancreas, resulting in little or no insulin production rather than insulin resistance. Gestational diabetes occurs during pregnancy and may involve insulin resistance as well, but it typically resolves after childbirth. "Easy onset diabetes" is not a recognized medical term, and thus does not accurately describe any type of diabetes.
