home monitoring for adrenal
Informed by recognized medical guidance
Overview
Home monitoring for adrenal means that people with adrenal insufficiency (a condition where the adrenal glands do not produce enough hormones) learn to track their health at home. They watch for signs of stress or illness and adjust their medicines under a doctor’s plan. This helps prevent a dangerous situation called an adrenal crisis.
Key facts
- Adrenal insufficiency is a lifelong condition that requires daily hormone replacement therapy.
- Home monitoring helps you catch problems early, like when you are sick or stressed.
- You may need to increase your medicine dose during illness—this is called 'sick day rules'.
- Always follow your doctor’s written sick day plan and never change your dose without guidance.
Adrenal insufficiency is rare, but home monitoring is a standard part of care for everyone who has it.
People of any age can have adrenal insufficiency. It affects those with primary adrenal insufficiency (Addison’s disease) and those with secondary adrenal insufficiency (caused by pituitary gland problems or long-term steroid use).
Symptoms
- Extreme weakness or collapse
- Severe vomiting or diarrhea that prevents taking medicine
- Unconsciousness or seizures
- Severe abdominal pain, often with back pain
- Low blood sugar with confusion or inability to eat
- ⚠Fever above 38°C (100.4°F) that does not improve with paracetamol
- ⚠Belly pain with vomiting but still able to take oral medicine
- ⚠Severe diarrhoea or vomiting that lasts more than a few hours
- ⚠Injury or surgery that requires extra stress dosing
Common symptoms
- Fatigue and weakness
- Weight loss or poor appetite
- Darkening of the skin (in primary adrenal insufficiency)
- Low blood pressure (feeling dizzy when standing up)
- Salt craving
- Nausea, vomiting, or belly pain
Symptoms in children
- Poor growth or weight gain
- Frequent infections
- Low energy and irritability
- Blood sugar swings
Symptoms in older adults
- Confusion or falls due to low blood pressure
- Worsening of other health problems
- More severe dehydration during illness
Causes
Main causes
- Primary adrenal insufficiency (Addison’s disease) – often caused by the immune system attacking the adrenal glands.
- Secondary adrenal insufficiency – caused by damage to the pituitary gland or from suddenly stopping long-term steroid medicines.
- Other causes: infections (like tuberculosis), bleeding into the adrenals, or genetic conditions.
Risk factors
- Autoimmune diseases (such as type 1 diabetes or thyroid problems)
- Long-term use of corticosteroids (like prednisone)
- Pituitary tumours or surgery
- Family history of autoimmune adrenal disease
When to see a doctor
See a doctor urgently if:
- If you have symptoms of adrenal crisis (see emergency list above), call your local emergency number right away.
- If you are vomiting and cannot keep down your medicine, go to the emergency department.
Book a routine appointment if:
- See your endocrinologist (hormone specialist) regularly – usually every 6–12 months – for blood tests and medicine review.
- Contact your doctor if you have had a recent illness or injury that required extra stress dosing, to discuss next steps.
Diagnosis
Diagnosis is made by a doctor, usually an endocrinologist. They will take your medical history, do a physical exam, and order special blood tests. Home monitoring is not used to diagnose the condition – it comes after diagnosis to help you manage it safely.
Tests that may be done
- Blood tests: measure cortisol and ACTH levels
- ACTH stimulation test (Synacthen test) – the gold standard
- Blood electrolytes (sodium and potassium) and blood sugar
- Adrenal antibody tests (for autoimmune causes)
- Imaging (CT scan of adrenal glands) if needed
What to expect at your appointment
You will be given a written plan for monitoring at home, including when to take extra medicine. You may be taught to check your blood pressure, weight, and how to recognise early warning signs. Your doctor will tell you exactly what to do for common illnesses like a cold or stomach bug.
Treatment
Treatment for adrenal insufficiency replaces the hormones your adrenal glands cannot make. This is usually taken as pills every day. Home monitoring helps you adjust your medicine during times of stress, illness, or injury to avoid a crisis.
Self-care at home
- Take your prescribed hormone replacement exactly as directed, every day.
- Learn and follow your sick day rules: double or triple your dose during fever, infection, or injury, as instructed by your doctor.
- Wear a medical alert bracelet or carry a steroid emergency card.
- Keep an emergency injection kit (if prescribed) and know how to use it.
- Monitor your weight, blood pressure, and how you feel – especially when unwell.
Medical treatments
Hormone replacement therapy is the main treatment. This includes a glucocorticoid (such as hydrocortisone) to replace cortisol, and sometimes a mineralocorticoid (such as fludrocortisone) to replace aldosterone. Your doctor will adjust the dose based on your symptoms and blood tests. During severe illness or injury, you may need an injection of hydrocortisone given by you or a family member, followed by urgent medical care.
When is surgery considered?
If you need surgery, your medical team will give you extra steroids before and after the procedure to support your body during the stress of surgery. This is carefully planned with your endocrinologist.
Living with this condition
Most people with adrenal insufficiency take medicine twice or three times a day and carry an emergency kit. You will need to plan ahead for travel, illness, and physical activity. With a good routine, you can work, exercise, and enjoy life.
Lifestyle tips
- Always carry your medicine and emergency injection kit with you.
- Wear a medical alert ID at all times.
- Learn to recognise early signs of stress on your body.
- Tell your close friends, family, and colleagues about your condition and what to do in an emergency.
Diet and exercise
A balanced diet is important. Some people need extra salt, especially in hot weather or after exercise. Drink plenty of fluids. Exercise is safe, but increase your dose if you are doing intense or prolonged activity – follow your doctor’s advice.
Mental health and emotional wellbeing
Living with a chronic condition can be stressful. It is normal to feel anxious about the risk of a crisis. Talk to your doctor about these feelings. If you feel very worried, sad, or hopeless, reach out to a mental health professional. In a crisis, contact your local crisis helpline or go to your nearest emergency department.
Prevention
Adrenal insufficiency itself is not preventable. However, with home monitoring and a good sick day plan, you can prevent adrenal crises and live well. If you take steroids for another condition, never stop them suddenly – this can cause adrenal insufficiency.
Vaccines
Stay up to date with recommended vaccines, such as the flu vaccine and pneumococcal vaccine, to reduce the chance of infections that could trigger a crisis.
Screening programmes
If you have an autoimmune condition, your doctor may check your adrenal function from time to time. Routine screening for the general population is not recommended.
Complications
If left untreated
- Adrenal crisis – a life-threatening emergency with severe vomiting, low blood pressure, and loss of consciousness.
- Long-term fatigue, weakness, and low blood pressure that affect daily life.
- Electrolyte imbalances (high potassium, low sodium) that can harm the heart.
Long-term outlook
With proper treatment and home monitoring, the outlook for people with adrenal insufficiency is very good. You can expect to live a normal lifespan and enjoy most activities. The key is learning how to manage your condition and working closely with your healthcare team.
