What happens if pituitary gland is not functioning properly?

Specific conditions that involve a deficiency of a pituitary hormone include: Growth hormone deficiency: This condition happens when your pituitary doesn’t release enough growth hormone (GH). In children, it causes a lack of growth and development and delayed puberty. In adults, it causes metabolic issues.

How long can you live with a pituitary tumor?

The 5-year survival rate tells you what percent of people live at least 5 years after the tumor is found. Percent means how many out of 100. The 5-year survival rate for people with a pituitary gland tumor is 97%. Survival rates depend on the type of tumor, the person’s age, and other factors.

What does a pituitary tumor headache feel like?

Symptoms. A person with pituitary tumor apoplexy usually has a sudden-onset, severe headache at the front of the head (either located on one side of the head or both) and/or behind one or both eyes.

What causes pituitary tumors to grow?

The causes of pituitary tumors are unknown. Some tumors are caused by hereditary disorders such as multiple endocrine neoplasia I (MEN I). The pituitary gland can be affected by other brain tumors that develop in the same part of the brain (skull base), resulting in similar symptoms.

What causes pituitary tumor in dogs?

Can pituitary tumors be treated without surgery?

Radiation therapy uses high-energy x-rays to kill abnormal pituitary tumor cells. Radiation is extremely effective in stopping tumor growth and, with time, will lead to tumor shrinkage. Radiation therapy may be an option if the tumor cannot be treated effectively through medication or surgery.

What shrinks pituitary tumor?

Drugs called dopamine agonists can stop prolactinomas from making too much prolactin and shrink these tumors. Drugs are often the only treatment needed. Cabergoline (Dostinex) and bromocriptine (Parlodel) are most commonly used.

Are all pituitary tumors cancerous?

Most pituitary tumors are not cancerous (benign). They don’t spread to other parts of your body. But they can cause the pituitary to make too few or too many hormones, causing problems in the body. Pituitary tumors that make too many hormones will cause other glands to make more hormones.
