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.
Acromegaly is caused by the uncontrolled hypersecretion of growth hormone (GH) by the pituitary, a tiny gland â about the size of a pea ââ located just below your brain, behind your eyes.rowth Hormone (GH) - The pituitary releases GH in short spurts throughout the day and night, resulting in constantly varying GH levels. When a person has acromegaly, abnormally high levels of GH are released by the pituitary. Too much GH causes changes in physical characteristics and other aspects of your body.
