Insulin meaning

Insulin is a vital hormone produced by the beta cells of the pancreas in response to elevated blood glucose levels, typically after eating. It facilitates the uptake of glucose into cells, particularly in muscle and adipose tissue, where it is used for energy production or stored for future use. Insulin also inhibits the breakdown of fats and proteins, promoting an anabolic state within the body. Proper insulin function is crucial for maintaining blood sugar levels within a narrow range. In diabetes mellitus, either the body's production of insulin is insufficient (Type 1 diabetes) or the cells become resistant to its effects (Type 2 diabetes), leading to hyperglycemia and a range of potential complications if not managed properly.
