The condition characterized by the body's inability to respond effectively to insulin is insulin resistance. This phenomenon occurs when the body's cells, including those in the liver, muscle, and fat tissue, do not respond properly to insulin, which is a hormone essential in regulating blood sugar levels.

In healthy individuals, insulin binds to its receptors on these cells, facilitating the uptake of glucose from the bloodstream into the cells. However, in insulin resistance, this process is impaired, resulting in elevated blood glucose levels. This condition is often seen in type 2 diabetes and is associated with obesity, sedentary lifestyle, and genetic factors.

Understanding insulin resistance is critical, as it can lead to metabolic syndrome, cardiovascular disease, and the eventual development of type 2 diabetes if not addressed. Effective management often involves lifestyle changes such as diet and exercise, along with medications as needed.
