Which condition results from the body producing too much insulin?

The condition that results from the body producing too much insulin is hypoglycemia. When excessive amounts of insulin are released into the bloodstream, it causes a significant drop in blood glucose levels. Insulin drives glucose from the blood into the cells, and when it is present in high quantities, it can deplete the blood glucose to dangerously low levels, resulting in symptoms such as shakiness, sweating, confusion, and in severe cases, loss of consciousness.

In contrast, diabetes mellitus is characterized by insufficient insulin production or the body's inability to properly use insulin, leading to elevated blood glucose levels rather than low ones. Hyperglycemia refers to high blood glucose levels, typically a consequence of insufficient insulin or insulin resistance. Metabolic syndrome is a cluster of conditions, including high blood pressure and elevated blood sugar, that increase the risk of heart disease and diabetes but does not directly stem from high insulin production alone. Each of these conditions highlights different aspects of insulin's role in glucose metabolism, but hypoglycemia specifically pertains to the effects of excess insulin.
