Cortisol is a steroid hormone that is produced in the adrenal glands, which are located on the upper poles of the kidneys. It is a type of glucocorticoid hormone. The raw material used for the synthesis of cortisol is cholesterol. The adrenal glands synthesize cortisol in response to the ACTH hormone, which is released in the pituitary gland. It serves various functions in the body. Cortisol plays a central role in glucose metabolism. In the setting of hypoglycemia, it stimulates the liver to synthesis glucose. It down regulates the immune system by suppressing the release of inflammatory mediators and preventing antibody formation. This is why steroids play a central role in the management of inflammatory and autoimmune conditions. Cortisol is also popularly known as the stress hormone. It is released when the body is under stress and it helps keep the body in optimum condition to bear with the stress. During pregnancy, it stimulates synthesis of surfactant which is crucial for fetal lung maturation.
