What blood test checks your pituitary gland?

Can pituitary tumors cause sinus problems?

Based on size, pituitary tumors can be either microadenomas (less than 10mm) or macroadenomas (larger than 10mm). Large tumors can press on the optic nerves and invade the cavernous sinuses, which house the carotid arteries and the nerves involved in eye movement.

Can an eye doctor see a pituitary tumor?

Because of their effects on vision, eye doctors may be the first to diagnose a pituitary adenoma. To measure the extent of vision loss, eye doctors usually order a computerized visual field test. Because some pituitary tumors can cause hormonal changes, a complete medical history is also taken.

Pituitary gland tumors are usually benign, but they can cause a host of problems that often show up as blurred or double vision, dizzy spells. They can develop into Cushing’s disease, or in the case of Pritchard, abnormal growth called acromegaly.

Is a pituitary tumor serious?

Can pituitary tumors cause eye problems?

Patients with small pituitary tumors do not typically develop visual symptoms. However, if a pituitary tumor has grown larger (usually more than 1 cm), then a patient can develop visual loss in one or both eyes. One pattern of visual loss that characteristically occurs is reduced peripheral vision to both sides.

Can stress cause pituitary tumors?

There are reliable research studies showing severe stress, childhood trauma, and/or physical trauma increase the likelihood of the development of a pituitary tumor.

Can a pituitary tumor cause ear problems?

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.
