Signs and Symptoms of Pituitary Tumors: An Introduction
The symptoms of a
pituitary tumor can range from simple, common complaints, such as tiredness or restlessness, to more serious symptoms, such as
headaches, vomiting, or dizziness.
Symptoms vary, depending on the size and location of the tumor. If the tumor grows large and presses on nearby parts of the brain, symptoms such as
headaches or dizziness can occur. A
pituitary tumor can also press on the optic nerve, causing problems with vision.
Symptoms of a pituitary tumor also vary based on the hormones the tumor is producing.
Prolactin-Producing Tumors (Prolactinoma)
Prolactinomas are the most common pituitary tumors. Prolactinoma symptoms caused by the high prolactin levels produced by such a tumor can include:
- Infertility.
- Changes in menstruation. In some women, periods may disappear altogether. In others, periods may become irregular or menstrual flow may change.
- Women who are not pregnant or nursing may begin producing breast milk.
- Loss of libido (interest in sex).
- Vaginal dryness.
- Painful intercourse (because of vaginal dryness).
- Headaches.
- Eye problems caused by the enlarged pituitary pressing against nearby eye nerves.
