Overview
Hypopituitarism is a disorder in which the pituitary gland does not produce normal amounts of some or all of its hormones. Common causes may be genetic mutations, head trauma, brain tumor, brain surgery, radiation treatment, autoimmune inflammation, stroke, infections of the brain, tuberculosis, ans so on. Usual signs and symptoms include abdominal pain, loss of appetite, hypotension, fatigue and weakness, headache, short stature and disorder in secondary sexual characters. Hormone tests, bone age x-ray test and cranial MRI may help disgnosis. Treatments of hypopituitarism focus on the cause of the disease and hormone replacement therapy.
What are the symptoms?
Signs and symptoms of hypopituitarism vary, depending on which pituitary hormones are deficient.
- Abdominal pain
- Loss of appetite and weight loss
- Hypotension
- Sensitivity to cold
- Visual disturbances
- Fatigue and weakness
- Headache
- Slowed growth and sexual development in children
- Short stature
- Loss of armpit or pubic hair, loss of body or facial hair in men
- Cessation of menstrual periods and infertility in women
- Decreased sexual interest in both men and women
Other health problems may also cause these symptoms. Only a doctor can tell for sure. A person with any of these symptoms should tell the doctor so that the problems can be diagnosed and treated as early as possible.
Who is at highest risk?
- Head trauma
- Brain tumor
- Brain surgery
- Radiation treatment
- Autoimmune inflammation, such as hypophysitis
- Stroke
- Infections of the brain, such as meningitis
- Tuberculosis
- Infiltrative diseases, such as sarcoidosis, histiocytosis X, hemochromatosis.
- Severe loss of blood: Sheehan syndrome, or postpartum hypopituitarism
- Genetic mutations
Diagnosis
- Hormone tests: Patients with hypopituitarism may show low levels of thyroid, adrenal or sex hormones. And the doctor can determine whether these low levels are associated with inadequate pituitary hormone production.
- Bone age x-ray test: Comparing to normal children, bone age test in patients with hypopituitarism may demonstrate a delayed physical maturation.
- Cranial CT or MRI: Since brain diseases are the most common cause of this condition, it may show pituitary tumor signs and other characteristics in MRI.
When to seek urgent medical care?
If you develop signs and symptoms associated with hypopituitarism, see your doctor to determine the cause. If you experience either of the following symptoms, seeking urgent medical care as soon as possible:
Treatment options
Treatment opinion depends on the cause and the hormaone types insufficient.
- Treatments of tumor: Surgical removal of tumor is the first selection for the treatment. If failed, radiation therapy, or gamma knife radiation treatment may be helpful.
- Hormone replacement therapy: This is needed to replace hormones that are no longer made by organs under the control of the pituitary gland, including corticosteroids, growth hormone, sex hormones and thyroid hormone. LH and FSH are used in infertile women.

Prevention
At present, there is no preventable measure for hypopituitarism.
What to expect (Outook/Prognosis)?
Prognosis of hypopituitarism depends on:
- The cause of hypopituitarism: Prognosis of hypopituitarism resulting from tumor is worse than other causes.
- The reaction of hormone replacement therapy.
