The symptoms of a pituitary tumor vary drastically based on whether the tumor is functioning or non-functioning.

What are common symptoms of pituitary tumors?

Symptoms depend on the size and type of tumor your child has, and the hormone (if any) that the tumor makes. If the tumor makes a certain hormone, the symptoms are related to having too much of that hormone.

Smaller tumors sometimes do not have any symptoms. Larger tumors are more likely to cause headaches and vision problems. Large tumors may also press against pituitary cells that make other hormones. This causes a deficiency of these hormones.

Other possible symptoms include:

  • Headache
  • Vision loss
  • Changes in periods (in girls)
  • Milky discharge from breasts
  • Fatigue (feeling very tired)
  • Dizziness
  • Nausea (upset stomach)
  • Weight loss or weight gain
  • Poor growth or excessive growth (for height)
  • Trouble sleeping
  • High blood pressure
  • High blood sugar
  • Mood changes, like anxiety or depression
  • Constipation
  • Dull and dry skin
  • Hair loss
