Adrenalectomy is the surgical removal of the adrenal gland. The adrenals are two small glands located on top of each kidney, just below the rib cage. They produce hormones that help regulate blood pressure, heart rate, body temperature, sleep patterns, and other functions. In some cases, these hormones can be overproduced by the adrenal glands due to a tumor.
It may cause symptoms such as fatigue, muscle weakness, weight gain, and low energy levels when this happens. If the tumor is cancerous, it may spread cancer to other parts of the body in which a surgeon may also recommend an adrenalectomy. If left untreated, these conditions can lead to more serious problems.
