What Are Pituitary Tumor Symptoms?
Pituitary tumor symptoms vary based on the type of cells involved. For example, a pituitary tumor made up of prolactin cells may make too much prolactin hormone. This can cause:
- Breast milk production.
- Menstrual cycle changes.
- Infertility (which can be corrected with treatment).
A pituitary tumor involving the cells that produce growth hormones may cause faster-than-normal growth.
Pituitary tumors involving cortisol-producing cells can lead to a condition called Cushing’s disease, or Cushing’s syndrome. Symptoms of Cushing’s syndrome include:
- Abnormal marks on the skin
- Excessive weight gain
- High blood pressure
- Muscle weakness
- Weakened bones (osteoporosis)
Some pituitary tumors don’t produce excess hormones. These tumors, called null cell adenomas, can go undetected. They can grow large enough to affect nearby cells or push on nearby structures. Symptoms of null cell adenoma include:
- Hypopituitarism (hormone deficiencies)
- Vision problems
Do Pituitary Tumors Cause Headaches?
Nearly all types of pituitary tumors can cause headaches. Other common symptoms of pituitary tumors include:
- Confusion
- Dizziness
- Nausea and vomiting
- Runny or “drippy” nose
Can Pituitary Tumors Cause Seizures?
Large pituitary tumors that put pressure on the brain can lead to seizures.
