Adrenal Disorders in BC: Cushing's, Addison's & Adrenal Insufficiency

Last Updated: June 2026

Adrenal disorders affect thousands of British Columbians each year, disrupting the body's ability to produce essential hormones that regulate metabolism, blood pressure, immune function, and stress response. Conditions such as Cushing's syndrome, Addison's disease, and adrenal insufficiency require specialized endocrinology care for accurate diagnosis and effective management. Understanding how to navigate BC's healthcare system for these complex conditions can significantly improve outcomes and reduce the time between symptom onset and treatment.

Understanding the Adrenal Glands and Their Function

The adrenal glands are small, triangular organs located on top of each kidney. Despite their small size, these glands produce hormones critical to survival, including cortisol, aldosterone, and adrenaline. When adrenal function becomes impaired through overproduction, underproduction, or tumour growth, the resulting disorders can affect nearly every system in the body.

In British Columbia, adrenal disorders are diagnosed and managed through a combination of primary care, specialist referrals, and hospital-based endocrinology programs. Early recognition of symptoms and timely referral to an endocrinologist are essential for preventing serious complications.

Common Adrenal Disorders Affecting British Columbians

Cushing's Syndrome

Cushing's syndrome occurs when the body is exposed to high levels of cortisol over an extended period. This can result from the adrenal glands producing excess cortisol, a pituitary tumour stimulating cortisol production (Cushing's disease), or long-term use of corticosteroid medications. Symptoms typically include weight gain concentrated in the face and midsection, purple stretch marks, muscle weakness, high blood pressure, and mood changes.

The estimated prevalence of Cushing's syndrome is approximately 40 to 70 cases per million people, meaning BC likely has several hundred active cases at any given time. Diagnosis often requires multiple hormone tests, imaging studies, and specialist evaluation to determine the underlying cause.

Addison's Disease (Primary Adrenal Insufficiency)

Addison's disease occurs when the adrenal glands fail to produce sufficient cortisol and often aldosterone. In Canada, autoimmune destruction of the adrenal glands accounts for approximately 80% of cases, though infections, cancer, and genetic conditions can also cause this disorder. Symptoms develop gradually and include chronic fatigue, muscle weakness, weight loss, low blood pressure, salt cravings, and darkening of the skin.

Primary adrenal insufficiency affects roughly 100 to 140 people per million, suggesting approximately 500 to 700 British Columbians live with this condition. Without proper diagnosis and hormone replacement therapy, Addison's disease can lead to life-threatening adrenal crisis.

Secondary and Tertiary Adrenal Insufficiency

Secondary adrenal insufficiency results from pituitary gland dysfunction, while tertiary adrenal insufficiency stems from hypothalamic problems. The most common cause of secondary adrenal insufficiency is the sudden discontinuation of corticosteroid medications after long-term use. These forms of adrenal insufficiency are actually more common than Addison's disease, affecting an estimated 150 to 280 people per million.

Adrenal Tumours and Incidentalomas

With the increased use of CT and MRI imaging across BC, adrenal incidentalomas (tumours discovered incidentally during imaging for other reasons) are found in approximately 4% to 5% of abdominal scans. Most are benign and non-functional, but some produce excess hormones or carry malignant potential. Evaluation by an endocrinologist helps determine which tumours require monitoring, medical treatment, or surgical removal.

Diagnosing Adrenal Disorders in BC

Diagnosis of adrenal disorders typically begins with your family physician, who will order initial blood tests and may refer you to an endocrinologist for specialized evaluation. The diagnostic process often includes:

• Blood cortisol testing: Morning cortisol levels, ACTH stimulation tests, and 24-hour urinary free cortisol measurements
• Aldosterone and renin levels: To assess mineralocorticoid function
• ACTH measurements: To distinguish between primary and secondary causes
• Dexamethasone suppression tests: Used in Cushing's syndrome diagnosis
• Imaging studies: CT scans and MRI of the adrenal glands and pituitary
• Specialized testing: Inferior petrosal sinus sampling for Cushing's disease localization

Most routine blood tests are covered under MSP when ordered by a physician. Advanced imaging and specialized testing are also covered, though wait times vary by health authority and facility. For more information about what services are covered, visit HealthLinkBC (8-1-1).

Accessing Endocrinology Care Across BC

Adrenal disorders require ongoing management by endocrinologists, physicians who specialize in hormone-related conditions. Accessing specialist care in BC varies significantly by region.

Vancouver and Lower Mainland

The Vancouver area offers the most comprehensive endocrinology services in the province. Major centres include Vancouver General Hospital, St. Paul's Hospital, and academic practices affiliated with UBC. Surrey, Burnaby, Richmond, and Abbotsford also have endocrinologists practicing in hospital outpatient clinics and private offices.

Current wait times for non-urgent endocrinology referrals in the Lower Mainland typically range from 3 to 8 months, though urgent referrals for suspected adrenal crisis or functioning tumours may be seen within 2 to 4 weeks. Complex cases requiring multidisciplinary input, such as Cushing's disease requiring pituitary surgery, are generally managed at Vancouver General Hospital or St. Paul's Hospital.

Victoria and Vancouver Island

Victoria has several endocrinologists practicing at Royal Jubilee Hospital and in private clinics. Wait times for routine referrals typically range from 4 to 10 months. Patients in smaller Vancouver Island communities may need to travel to Victoria or be referred to Vancouver for complex adrenal cases.

Interior and Northern BC

Kelowna serves as the main endocrinology hub for the BC Interior, with specialists at Kelowna General Hospital. Wait times often extend to 6 to 12 months for non-urgent cases. Northern BC has limited endocrinology services, with many patients travelling to Vancouver or accessing care through telehealth programs.

Telehealth Options

Virtual endocrinology consultations have expanded significantly across BC, improving access for patients in rural and remote communities. While initial assessments and follow-up appointments can often be conducted virtually, certain examinations and procedures still require in-person visits.

Treatment Approaches for Adrenal Disorders

Treatment varies significantly depending on the specific condition and its underlying cause:

Cushing's Syndrome Treatment

Treatment depends on the cause. Pituitary tumours (Cushing's disease) typically require transsphenoidal surgery, performed at specialized centres in Vancouver. Adrenal tumours may require adrenalectomy. When caused by corticosteroid medications, gradual dose reduction under medical supervision is necessary. Some patients require medications to control cortisol production before or instead of surgery.

Addison's Disease and Adrenal Insufficiency Treatment

Lifelong hormone replacement therapy is required, typically including hydrocortisone or prednisone to replace cortisol and fludrocortisone to replace aldosterone in primary adrenal insufficiency. Patients must learn to adjust their medication doses during illness or stress and carry emergency injection kits for adrenal crisis prevention.

Most replacement medications are covered under BC PharmaCare for eligible patients, with typical monthly costs of $30 to $80 CAD for those paying out of pocket. Emergency hydrocortisone injection kits cost approximately $50 to $100 CAD.

Adrenal Tumour Management

Non-functioning benign tumours may only require periodic imaging surveillance. Functioning tumours or those with concerning features typically require surgical removal. Laparoscopic adrenalectomy is performed at major centres in Vancouver, Victoria, and Kelowna, with excellent outcomes for appropriately selected patients.

Living with an Adrenal Disorder in BC

Managing an adrenal disorder requires ongoing medical care, patient education, and lifestyle adjustments. Key considerations for BC patients include:

• Medical alert identification: Patients with adrenal insufficiency should wear medical alert bracelets and carry emergency information cards
• Sick day protocols: Learning when and how to adjust medication doses during illness is critical for preventing adrenal crisis
• Emergency preparedness: BC's seismic risk and potential for natural disasters make emergency medication supplies essential
• Travel planning: Carrying adequate medication supplies and medical documentation when travelling within BC or beyond
• Support resources: Connecting with patient organizations such as the Canadian Addison Society for education and peer support

When to Seek Urgent Care

Adrenal crisis is a medical emergency requiring immediate treatment. Warning signs include severe weakness, confusion, severe abdominal or leg pain, vomiting, low blood pressure, and loss of consciousness. Patients experiencing these symptoms should call 911 or proceed to the nearest emergency department immediately. In BC, major emergency departments in Vancouver, Surrey, Burnaby, Richmond, Victoria, Kelowna, and Abbotsford are equipped to manage adrenal emergencies.

Navigating Your Care Journey

If you suspect you may have an adrenal disorder or have received a new diagnosis, taking organized steps can help you access appropriate care efficiently:

1. Start with your family physician or walk-in clinic for initial assessment and blood work
2. Request a referral to an endocrinologist, noting any urgent symptoms that may expedite the process
3. Keep detailed records of your symptoms, test results, and medications
4. Prepare questions before specialist appointments to maximize your consultation time
5. Ask about telehealth options if travelling to appointments is challenging
6. Connect with patient support organizations for education and community resources

Understanding how to navigate BC's healthcare system for adrenal disorders can reduce delays in diagnosis and treatment. While wait times for specialist care remain challenging in many regions, options such as telehealth consultations, urgent referral pathways for serious symptoms, and comprehensive care at major centres ensure that British Columbians can access the specialized endocrinology care these complex conditions require.
