The organ primarily responsible for producing insulin is the pancreas. Located behind the stomach, the pancreas plays a critical role in regulating blood sugar levels. It produces insulin, a hormone that facilitates the uptake of glucose into cells for energy or storage. Insulin helps maintain homeostasis by keeping blood sugar levels within a healthy range. In people with diabetes, either the pancreas does not produce enough insulin or the body becomes resistant to it, leading to elevated blood sugar levels. Managing insulin production is therefore vital for metabolic health and overall well-being.
