Pituitary Gland Disorders

The pituitary gland, a pea-sized organ at the base of the brain, serves as the body’s “master gland,” controlling key hormones that regulate growth, metabolism, reproduction, and stress. It sends signals to other endocrine glands, helping keep hormone levels balanced. When the pituitary malfunctions—through over- or under-production of hormones or growths like tumors—it can lead to various health problems.

Our team is adept at recognizing these endocrine signals. Identifying an endocrine cause is vital, because treating the underlying hormonal disorder can significantly improve or even cure the hypertension in such cases.

Common Pituitary Disorders

Pituitary gland disorders can broadly manifest as either hormone deficiencies (underactivity) or hormone excess(overactivity), sometimes due to structural problems like tumors. Some common pituitary disorders include:

Hypopituitarism: This is when the pituitary gland produces too little of one or more hormones, often due to damage from tumors, surgery, or injury. Symptoms vary by which hormones are affected and may include fatigue, weakness, and growth issues. Treatment usually involves hormone replacement.
Pituitary Adenomas: These are benign tumors of the pituitary gland. Non-functioning adenomas may cause headaches or vision problems if large, while functioning adenomas produce excess hormones, leading to conditions like prolactinoma or acromegaly. Though not cancerous, they can disrupt hormone balance or press on nearby structures.
Cushing’s Disease: Caused by a pituitary tumor that releases too much ACTH, resulting in high cortisol. Symptoms include rapid weight gain, round face, high blood pressure, and muscle weakness. Treatment often involves surgery to remove the tumor and managing hormone levels before and after the procedure.

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.

Frequently Asked Questions (FAQs)

What does the pituitary gland do, and why is it called the “master gland”?

The pituitary gland, often called the “master gland,” controls other endocrine glands by releasing hormones that regulate growth, metabolism, reproduction, and stress responses. Even small imbalances in its function can affect many body systems.

What are common disorders of the pituitary gland?

Pituitary gland disorders often involve making too much or too little hormone. Underproduction, like hypopituitarism, leads to low levels of thyroid, adrenal, or sex hormones. Overproduction includes conditions such as hyperprolactinemia (high prolactin), acromegaly (high growth hormone), and Cushing’s disease (high cortisol), commonly caused by benign tumors. Non-tumor issues like diabetes insipidus also affect pituitary function.

What are the symptoms of a pituitary tumor?

A pituitary tumor (adenoma) can cause symptoms by making excess hormones or by pressing on nearby areas. Hormone-producing tumors cause specific symptoms like menstrual changes or enlarged features, depending on the hormone involved. Larger tumors may lead to headaches, vision problems (especially loss of side vision), dizziness, or reduced hormone levels, causing fatigue or low libido. If you notice these symptoms, see an endocrinologist for evaluation and possible MRI.

Do I need to see an endocrinologist for pituitary disorders and how often are check-ups?

Yes, pituitary disorders should be managed by an endocrinologist, as they specialize in hormone-related conditions. The frequency of check-ups depends on your specific diagnosis and its stability—initial visits may be every few months, but once your condition is stable, they may become less frequent. Regular follow-ups ensure your hormone levels and tumor size are monitored, helping maintain your health. Our HealthHub team will personalize your follow-up schedule and keep you on track for ongoing care.

Can pituitary gland disorders be treated without surgery?

Many pituitary disorders can be treated without surgery, depending on the condition. For example, hyperprolactinemia is often managed with medication, and acromegaly may also be controlled medically if surgery isn’t possible. Hormone deficiencies like hypopituitarism are treated with hormone replacement. Surgery is reserved for cases where it’s essential, such as large tumors affecting vision or when medication doesn’t work. At HealthHub Clinics, our endocrinologists focus on non-surgical treatments and only recommend surgery when absolutely necessary, ensuring you understand and are comfortable with your care plan.
