Insulin levels refer to the amount of insulin, a hormone produced by the pancreas, present in the bloodstream. Insulin plays a crucial role in regulating blood sugar levels by facilitating the uptake of glucose into cells for energy. When we eat, especially foods high in carbohydrates, insulin levels rise to help manage the increase in blood sugar. Normal insulin levels vary throughout the day, influenced by factors such as diet, physical activity, and overall health. Abnormal insulin levels can indicate conditions like diabetes or insulin resistance, which can lead to serious health issues if not managed properly.
