The muscles in the back of your tongue help you make certain sounds, like the letters k and hard g (like in the word go). Try saying these letters slowly, and you'll feel how the back of your tongue moves against the top of your mouth to create the sounds. The back of your tongue is important for eating as well.
The most common cause is a benign tumor in your pituitary gland, which is located under your brain. This tumor is not cancer. Because of the tumor, your body makes too much growth hormone. Once in a while, tumors in the pancreas, liver, or parts of the brain can cause high levels of growth hormone. That leads to higher levels of another hormone, called insulin-like growth hormone, which causes the symptoms you see.
Hypopituitarism is a disorder in which your body doesnât make enough pituitary hormones. The pituitary gland is a small, bean-shaped gland at the base of your brain. It plays a role in controlling your bodyâs endocrine system, a group of glands that produce and secrete hormones to regulate your bodyâs processes.In hypopituitarism, the pituitary gland fails to produce or doesnât produce enough of one or more of its hormones.When your pituitary gland doesnât produce enough hormones, your body functions are affected. The pituitary gland is responsible for releasing:1  Adrenocoricotropic hormone (ACTH), which stimulates the adrenal glands to produce cortisol and other hormones to help your body deal with stress.hen your pituitary gland doesnât produce enough hormones, your body functions are affected.
