👉 In medicine, a pituitary gland is a small organ located in the neck that secretes hormones that regulate various bodily functions. These hormones include growth hormone (GH), which helps build and repair tissues; thyroid hormones (THs) that regulate metabolism, immune function, and growth; and prolactin, an hormone that regulates milk production. Pituitary tumors can cause symptoms such as weakness, weight loss, and difficulty breathing, but they are usually benign and do not lead to serious health
