- A category encompassing disorders occurring in the pituitary gland located at the base of the brain, including states where hormones are excessive or deficient.
- Pituitary tumors are mentioned as a common cause, and injury can also be a contributing factor.
- Abnormalities in pituitary hormones affect growth and the regulation of function in other endocrine glands.
- Clinical manifestations may include fatigue, changes in growth, menstrual and sexual function changes, visual disturbances, etc., depending on the affected hormones and the size of the lesion.
- Symptoms and severity vary by individual depending on the cause, location and size of the lesion, age, sex, pregnancy status, and comorbidities.
- The course varies depending on the type and cause of hormone excess or deficiency, and it may progress slowly or be discovered incidentally.
- Diagnosis is determined by comprehensively evaluating symptoms and medical history, hormone testing of the pituitary gland and target endocrine axes, and brain MRI if necessary.
- Hormone levels can be influenced by time of day, stress, medication, and acute illness, making it difficult to confirm dysfunction based on a single test alone.
- Management involves follow-up primarily by an endocrinologist while evaluating both the cause and hormonal abnormalities, with consultation with neurosurgery, ophthalmology, etc., if necessary.
- Treatment involves individually selecting hormone replacement or suppression, tumor treatment, surgery, or radiation therapy, depending on the cause and dysfunction.
