adrenal result meanings for patients

Overview

Adrenal results are the outcomes of blood or saliva tests that measure how well your adrenal glands are working. Your adrenal glands are small organs located above each kidney. They produce hormones like cortisol (which helps your body respond to stress) and aldosterone (which controls blood pressure and salt balance). Abnormal results can mean your adrenal glands are making too much or too little of these hormones.

Adrenal problems are not very common. For example, Addison's disease affects about 1 in 10,000 people, and Cushing's syndrome is even rarer. However, many people have mild abnormalities that are picked up during general health checks.

Adrenal issues can affect anyone, but some conditions are more common in certain groups. Addison's disease often appears in adults aged 30–50 and is slightly more common in women. Cushing's syndrome is more common in women and adults aged 20–50. Secondary adrenal insufficiency (pituitary gland not telling adrenals to work) can occur at any age.

Symptoms

Common symptoms

• If adrenal results show too little hormone (adrenal insufficiency): feeling very tired, weakness, weight loss, low blood pressure, darkening of the skin, craving salt.
• If adrenal results show too much hormone (Cushing's syndrome): weight gain (especially in the face and belly), thin skin that bruises easily, high blood pressure, muscle weakness, mood changes.
• If aldosterone levels are abnormal (Conn's syndrome): high blood pressure, low potassium causing muscle cramps or weakness, excessive thirst and urination.

Symptoms in children

• In children, adrenal issues can cause poor growth (short stature), delayed puberty, or problems with school performance due to fatigue or mood changes.
• Congenital adrenal hyperplasia (a genetic condition) may present with early signs of puberty in boys or girls, and in girls, ambiguous genitalia at birth.
• Children with adrenal insufficiency may have repeated low blood sugar episodes, leading to confusion or fainting.

Symptoms in older adults

• Older adults may have non-specific symptoms like fatigue, falls due to low blood pressure, or confusion that can be mistaken for aging or dementia.
• Changes in appetite and weight (either loss in adrenal insufficiency or gain in Cushing's) can be significant.
• Older adults are more prone to side effects from steroid medications, which can lead to secondary adrenal insufficiency.

Causes

Main causes

• The most common cause of adrenal insufficiency is from taking corticosteroids (like prednisolone) for a long time and then stopping suddenly. This suppresses the adrenal glands.
• Addison's disease is often caused by the immune system attacking the adrenal glands (autoimmune).
• Cushing's syndrome is usually caused by taking high doses of corticosteroids, or sometimes by a growth (tumour) on the adrenal or pituitary gland.

Risk factors

• Having other autoimmune conditions (like type 1 diabetes or thyroid disease) increases the risk of Addison's disease.
• Long-term use of steroid medications for asthma, arthritis, or other conditions raises the risk of adrenal suppression and Cushing's syndrome.
• Family history – some adrenal conditions run in families (e.g., congenital adrenal hyperplasia).

When to see a doctor

See a doctor urgently if:

• If you have symptoms of an adrenal crisis: severe pain, vomiting, confusion, or fainting – go to the emergency department immediately.
• If you are on steroids and become severely ill or need surgery – you may need extra steroids (stress dose). Contact your doctor urgently.

Book a routine appointment if:

• If you have ongoing fatigue, weight changes, or blood pressure problems that have not been explained.
• If you have been on steroid medication for more than a few weeks and are concerned about side effects.
• If you have a family history of adrenal disease and are experiencing symptoms.

Diagnosis

Adrenal problems are diagnosed through a combination of blood tests, urine tests, and sometimes scans or stimulation tests. The specific tests depend on which hormones are suspected to be off.

Tests that may be done

• Blood tests to measure cortisol, ACTH, aldosterone, renin, and DHEA-S.
• A 24-hour urine collection to measure cortisol levels throughout the day.
• The ACTH stimulation test (Synacthen test) – a synthetic version of ACTH is injected, and then blood cortisol is measured to see how well the adrenal glands respond.
• Imaging scans like CT or MRI of the adrenal or pituitary glands if a tumour is suspected.

What to expect at your appointment

You may need to fast or stop certain medications before the tests. For the ACTH stimulation test, you will have blood drawn and then receive an injection; another blood sample is taken after 30-60 minutes. It is done in a clinic and takes about an hour. Results usually come back in a few days to a week.

Treatment

Treatment depends on whether the adrenal glands are producing too little or too much hormone. The goal is to restore normal hormone balance and manage any underlying cause.

Self-care at home

• If you have adrenal insufficiency: always carry a steroid emergency card or wear a medical alert bracelet. Learn how to increase your steroid dose during illness (sick day rules) as advised by your doctor.
• Avoid sudden stopping of steroid medication – always follow your doctor's plan for tapering off.
• Manage stress, as physical or emotional stress can trigger symptoms. Plan ahead for sick days.

Medical treatments

Adrenal insufficiency is usually treated with replacement hormones, such as hydrocortisone (a form of cortisol) and fludrocortisone (for aldosterone). The doses are tailored to each person and adjusted during illness or stress. For Cushing's syndrome, treatment may involve reducing or stopping steroids if they are the cause, or surgery to remove a tumour. If surgery is not possible, medications can reduce cortisol production. Your doctor will explain the best plan for you.

When is surgery considered?

If a tumour in the adrenal gland (such as an adenoma) is causing excess hormone production, surgery to remove the gland (adrenalectomy) may be recommended. Pituitary tumours causing Cushing's disease are often removed via transsphenoidal surgery (through the nose).

Living with this condition

Living with an adrenal condition involves staying aware of your hormone levels and adjusting your medication as needed. With proper treatment, most people can do normal activities, work, and travel. Always have a sick-day plan and emergency supplies (injectable steroids if needed).

Lifestyle tips

• Maintain a regular schedule for meals and sleep to help your body cope with stress.
• Wear a medical alert bracelet or necklace that says 'adrenal insufficiency' so emergency workers know your condition.
• Keep emergency steroid medication (like an injection kit) with you, especially when traveling.

Diet and exercise

For adrenal insufficiency: eat regular meals to prevent low blood sugar. Increase salt intake if you have low aldosterone (salt craving is common). For Cushing's: a balanced diet low in sugar and healthy fats can help with weight management. Gentle exercise like walking or swimming is safe, but avoid overexertion.

Mental health and emotional wellbeing

Adrenal conditions can affect mood due to hormone imbalance. Depression, anxiety, or irritability are possible. Talk to your doctor if you feel overwhelmed – counselling or support groups can help.

Prevention

Most adrenal conditions cannot be prevented, especially if they are autoimmune or genetic. However, you can reduce the risk of secondary adrenal insufficiency by being cautious with long-term steroid use – always follow your doctor's instructions and never stop steroids abruptly.

Vaccines

If you have adrenal insufficiency, it is important to stay up to date with vaccinations, especially the annual flu jab and pneumococcal vaccine, as infections can trigger an adrenal crisis. Ask your doctor if you need any other vaccines.

Screening programmes

Routine screening for adrenal problems is not recommended for the general population. However, if you have symptoms or risk factors (like long-term steroid use), your doctor may suggest tests. Newborn screening for congenital adrenal hyperplasia is done in some countries (like the UK).

Complications

If left untreated

• Untreated adrenal insufficiency can lead to adrenal crisis – a life-threatening condition with very low blood pressure, shock, and coma.
• Uncontrolled Cushing's syndrome can cause serious health problems like high blood pressure, diabetes, osteoporosis (weak bones), and increased risk of infections.
• Long-term high aldosterone (Conn's syndrome) can damage the heart and kidneys if high blood pressure and low potassium are not managed.

Long-term outlook

With early diagnosis and proper management, most people with adrenal conditions can lead full, active lives. Adrenal insufficiency requires lifelong medication but can be very well controlled. Cushing's syndrome often improves after treatment, though some effects (like bone density) may take longer to recover. Regular follow-up with an endocrinologist is key to staying healthy.
