The pituitary gland is a tiny pea-sized organ at the base of the brain. It’s your master control gland for production of hormones. It makes hormones that affect your growth and the functions of other glands. If you have too much or too little of one hormone, you may have one of several pituitary disorders. Certain traumatic brain injuries can cause pituitary disorders, but the most common cause is pituitary gland tumors.

Pituitary Disorders

Your pituitary gland is a small bean-shaped gland at the base of your brain, just behind your nose and between your ears. Despite its small size, this gland secretes hormones that influence nearly every part of your body. Two common pituitary disorders are pituitary insufficiency, or hypopituitarism, and pituitary tumors. Hypopituitarism is a rare disorder where the pituitary either fails to produce one or more of its hormones or it doesn't produce enough of them. Such a hormone deficiency can affect your body’s routine functions, including growth, regulating blood pressure and reproduction. People with hypopituitarism typically need to be on medication for the rest of their lives, but their symptoms can be controlled.

Symptoms of Pituitary Disorders

Hypopituitarism is often progressive. Although symptoms can occur suddenly, they typically develop gradually, are sometimes subtle and may be overlooked for months or even years. Symptoms vary based on which pituitary hormones are deficient and how severe the deficiency is and may include:

  • Fatigue
  • Weight loss
  • Diminished sex drive
  • Sensitivity to cold, difficulty staying warm
  • Reduced appetite
  • Facial puffiness
  • Anemia
  • Infertility
  • Hot flashes
  • Irregular periods, loss of pubic hair, inability to produce milk for breast-feeding
  • Decreased facial or body hair in men
  • Short stature in children
