Adrenal surgery involves the removal of one or both adrenal glands, which are small glands located on top of each kidney. These glands produce hormones that regulate various bodily functions, including metabolism, immune response, and stress management. Surgery may be necessary to treat conditions such as adrenal tumors, Cushing's syndrome, or pheochromocytoma. The procedure can be performed using traditional open surgery or minimally invasive techniques, such as laparoscopic surgery. Recovery time varies depending on the method used and the patient's overall health. Post-surgery, patients may need hormone replacement therapy if both glands are removed or if the remaining gland does not function adequately.
