Because the pituitary gland controls the production of hormones throughout the body, pituitary disorders resemble other endocrine disorders and have a broad range of symptoms. Symptoms depend on the type and location of the tumor and cause hormone excess, hormone deficiency, or pressure on the brain and central nervous system.

Some tumors cause excess hormone production while others cause a deficiency, so one type of tumor may produce symptoms that are very different from those produced by another type of growth (for example, one may cause hair growth while the other causes hair loss).
The same tumor may begin by causing the release of excess hormone and then later result in a deficiency of that hormone as normal pituitary cells are suppressed. This would cause early symptoms that appear to be the opposite of later symptoms.
Some of the many symptoms associated with pituitary tumors include the following:
- Headache
-
Visual changes
- Double vision
- Drooping eyelids
- Personality changes
- Decreased sexual interest
