The pituitary gland is a small, pea-sized organ located at the base of the brain. It is often referred to as the “master gland” because it produces vital hormones that regulate growth, metabolism, thyroid function, reproduction, and other bodily processes. A pituitary tumour is an abnormal growth in this gland. Most pituitary tumours are benign (non-cancerous), but they can still cause serious health issues by:
Producing excess hormones (leading to conditions like Cushing’s disease, acromegaly, or thyroid disorders)
Pressing on nearby brain structures, such as the optic nerves, which can cause vision problems
Disrupting normal pituitary functions, resulting in hormone deficiencies
Treatment for pituitary tumours may include surgery, radiation therapy, medication, or a combination of these methods. India has emerged as a global destination for pituitary tumour treatment, thanks to its skilled neurosurgeons, advanced technology, high success rates, and affordable care.
The symptoms vary depending on whether the tumour produces excess hormones or compresses nearby structures:
Hormone-related symptoms
Overproduction of growth hormone → acromegaly (enlarged hands and feet, facial changes)
Overproduction of ACTH → Cushing’s disease (weight gain, round face, easy bruising)
Overproduction of prolactin → irregular periods in women, infertility, low testosterone in men
Excess thyroid-stimulating hormone (TSH) → hyperthyroidism
Pressure-related symptoms
Persistent headaches
Blurred or double vision
Vision loss, especially peripheral vision loss
Nausea or vomiting
Fatigue or weakness
The exact cause of pituitary tumors is not always known. However, factors include:
Genetic syndromes (like MEN type 1)
Random cell mutations leading to abnormal growth
Rarely, a family history of pituitary disorders
Most tumors develop sporadically without a clear trigger.
See a doctor immediately if you or your loved one experiences:
Sudden or worsening vision problems
Unexplained weight gain, irregular periods, or infertility
Excessive growth in hands, feet, or facial features
Persistent headaches
Severe fatigue, dizziness, or hormonal imbalance
Early diagnosis improves treatment outcomes significantly.
Family history of endocrine tumors
Genetic conditions (like multiple endocrine neoplasia)
Age 30–60 (though tumors can occur at any age)
Slightly more common in women for certain hormone-secreting tumors
Accurate diagnosis of a pituitary tumour involves a combination of hormonal evaluations, imaging studies, and sometimes vision assessments to determine the tumour’s type, size, and impact on nearby structures.
1. Physical Examination & Medical History
Your doctor will review your symptoms, such as headaches, vision changes, fatigue, or hormonal imbalances, and assess your overall health and medical history.
2. Hormone Blood and Urine Tests
Pituitary tumours often affect hormone production. Laboratory tests help measure levels of:
Prolactin
Growth hormone (GH)
Adrenocorticotropic hormone (ACTH)
Thyroid-stimulating hormone (TSH)
Cortisol and thyroid hormones
These results help determine whether the tumour is producing excess hormones (functioning tumour) or not (non-functioning tumour).
3. Imaging Tests
Magnetic Resonance Imaging (MRI): The primary imaging method to detect pituitary tumours, showing their size, location, and effect on surrounding tissues.
Computed Tomography (CT) Scan: Used when an MRI is not suitable, providing detailed cross-sectional images of the brain and skull base.
4. Vision (Ophthalmologic) Tests
Since the pituitary gland is located near the optic nerves, tumours can cause vision problems. Specialized eye exams assess:
Peripheral (side) vision
Visual acuity and field defects
5. Dynamic Testing (if needed)
In some cases, stimulation or suppression tests are performed to assess how the pituitary gland responds to specific hormones or medications.
Do’s:
Attend all follow-up appointments with your neurosurgeon and endocrinologist
Take medications as prescribed (especially hormone replacements)
Watch for symptoms like vision changes, extreme thirst, or fatigue
Maintain a healthy lifestyle with a good diet and exercise
Don’ts:
Don’t ignore persistent headaches or hormonal symptoms
Avoid self-medicating with over-the-counter hormones
Don’t miss scheduled imaging or lab tests
Recovery & Outlook
Most patients recover within 4 to 6 weeks after pituitary surgery.
Hormone-secreting tumors often improve significantly after treatment.
Lifelong follow-up may be needed to monitor hormone levels and tumor recurrence.
With expert care, patients can enjoy a normal, healthy life.
