Hyperprolactinemia
Hyperprolactinemia is a condition where the pituitary gland produces too much prolactin, the hormone responsible for milk production. Most often, this is caused by a benign tumor called a prolactinoma. Other causes include certain medications and hypothyroidism.
Symptoms in women include irregular periods, infertility, and unexpected breast milk production. Men may experience low libido, erectile dysfunction, and sometimes breast enlargement. Both sexes can develop headaches, vision changes, and low bone density if the tumor is large or hormone levels remain abnormal.
Fortunately, hyperprolactinemia is usually treatable. Medications can lower prolactin and shrink tumors, resolving most symptoms and restoring hormonal balance.
Acromegaly
Acromegaly is a rare disorder caused by excess growth hormone (GH), usually from a benign pituitary tumor. When the pituitary produces too much GH in adulthood, it leads to enlarged hands, feet, and facial features, as well as joint pain, headaches, and vision problems. Other symptoms may include oily skin, excessive sweating, fatigue, and carpal tunnel syndrome. If untreated, acromegaly can increase the risk of diabetes, high blood pressure, and heart disease.
Diagnosis is often delayed because symptoms develop gradually. At HealthHub, endocrinologists are trained to recognize these signs and use targeted tests to confirm the condition. Early diagnosis and treatment are important to prevent serious complications and improve quality of life.
Diagnosing Pituitary Gland Disorders at HealthHub
Diagnosing pituitary disorders often involves a combination of clinical evaluation, laboratory tests, and imaging studies. At HealthHub Clinics, we utilize advanced diagnostic tools to accurately identify pituitary gland disorders:
- Comprehensive Hormone Blood Tests: Our endocrinologists start with a thorough medical history and physical exam. If a pituitary disorder is suspected, we run targeted blood tests to check hormone levels. Additional tests may include thyroid, adrenal, and sex hormones.
- Visual Field Testing: Pituitary tumors may press on the optic nerves, causing changes in peripheral vision. At HealthHub, we use visual field tests to check for vision loss, especially loss of side vision. This simple, non-invasive exam helps detect patterns like bitemporal hemianopia, a key sign of pituitary tumors affecting the optic chiasm.
- Imaging Studies (MRI): To visualize the pituitary gland and any potential tumors, magnetic resonance imaging (MRI) is the gold standard. At HealthHub Clinics, we are proud to have an in-house MRI machine at our Festival City branch, ensuring quick and convenient access to this essential diagnostic tool. An MRI scan can clearly show the size and location of a pituitary adenoma or other abnormalities of the gland. This is crucial for planning treatment.
Treatment and Management at HealthHub Clinics
Treatment of pituitary gland disorders at HealthHub Clinics is tailored to each patient, focusing on effective, non-surgical therapies and long-term hormone management.
For hyperprolactinemia, medications like dopamine agonists (cabergoline or bromocriptine) lower prolactin levels and shrink tumors, often resolving symptoms. In acromegaly, medications such as somatostatin analogues or GH receptor blockers control growth hormone levels when surgery isn’t an option or after incomplete tumor removal.
If hormonal deficiencies occur due to hypopituitarism or after tumor treatment, hormone replacement therapy (for thyroid, adrenal, or sex hormones) is provided and carefully adjusted. Lifestyle advice and supportive care—like physiotherapy for joint pain, blood sugar management, and bone health monitoring—are also part of the approach.
Occasionally, surgery or radiation may be necessary for larger or more complex tumors. In such cases, HealthHub coordinates referrals with trusted neurosurgeons and continues managing your care after surgery.
