The pituitary gland sends signals to other glands, for example the thyroid gland, to produce hormones, such as thyroid hormone. The hormones produced by the pituitary gland and other glands have a significant impact on bodily functions, such as growth, reproduction, blood pressure, and metabolism.umors can cause damage to the pituitary gland or hypothalamus and can therefore result in a loss of function. Damage to the pituitary gland can also be caused by radiation, surgery, infections such as meningitis, or various other conditions. In some cases, the cause is unknown.
