adrenal screening test preparation
Informed by recognized medical guidance
Overview
Adrenal screening tests check how well your adrenal glands are working. These small glands on top of your kidneys make hormones that help your body handle stress, balance salt and water, and control blood pressure.
Key facts
- The adrenal glands produce hormones like cortisol and aldosterone.
- Screening involves simple blood, urine, or saliva tests.
- Preparation may include stopping certain medications or timing the test correctly.
Adrenal screening is not a routine test for everyone, but it is done when symptoms suggest an adrenal disorder.
It may be recommended for people with symptoms like unexplained weight gain, high blood pressure, fatigue, or hormone imbalances.
Symptoms
- Sudden severe pain in the belly, back, or legs
- Vomiting or diarrhea that won't stop
- Confusion or loss of consciousness
- Very low blood pressure causing fainting
- ⚠Severe weakness that is getting worse
- ⚠Rapid weight loss or unexplained fever
- ⚠New or worsening shortness of breath
Common symptoms
- Unexplained weight gain or weight loss
- High blood pressure
- Muscle weakness and fatigue
- Easy bruising or stretch marks on skin
- Changes in mood, like anxiety or depression
Symptoms in children
- Slow growth or delayed puberty
- Early signs of puberty in young children
- Frequent infections or poor weight gain
Symptoms in older adults
- Increasing frailty and muscle loss
- Confusion or memory problems
- Falls due to low blood pressure or weakness
Causes
Main causes
- Overproduction of hormones (like cortisol or aldosterone) by the adrenal glands
- Underproduction of hormones (adrenal insufficiency) often due to autoimmune damage
- Benign or cancerous tumors on the adrenal glands
Risk factors
- Family history of adrenal disorders
- Long-term use of corticosteroid medications
- Other autoimmune conditions (like Type 1 diabetes or thyroid disease)
- Certain infections or injuries affecting the adrenal glands
When to see a doctor
See a doctor urgently if:
- If you have symptoms of adrenal crisis (severe pain, vomiting, confusion, fainting)
- If you are on steroids and suddenly stop them without medical advice
Book a routine appointment if:
- If you have ongoing fatigue, weight changes, or high blood pressure
- If you notice stretch marks or easy bruising that came on quickly
Diagnosis
Your doctor will review your symptoms and order blood, urine, or saliva tests to measure hormone levels. Imaging scans may also be used to look at the adrenal glands.
Tests that may be done
- Blood test for cortisol and ACTH levels
- 24‑hour urine collection to measure hormone output
- Late-night saliva test for cortisol
- ACTH stimulation test to check adrenal response
- CT or MRI scan of the adrenal glands
What to expect at your appointment
You may need to stop certain medications or supplements before testing. Your doctor will give you specific instructions. For some tests, you will need to collect urine over 24 hours or have your blood drawn at a specific time of day. The process is usually straightforward and not painful.
Treatment
If screening shows an adrenal disorder, treatment depends on the cause and may include medication, lifestyle changes, or surgery.
Self-care at home
- Take all prescribed medications exactly as directed
- Manage stress through relaxation techniques or gentle exercise
- Wear a medical alert bracelet if you have adrenal insufficiency
Medical treatments
Your doctor may recommend hormone replacement therapy (to bring low hormones back to normal) or medications that block excess hormone production. The goal is to restore balance and relieve symptoms. Treatment is tailored to you.
When is surgery considered?
Surgery may be needed to remove a tumor that is causing hormone overproduction. Your healthcare team will discuss the risks and benefits with you.
Living with this condition
If you have an adrenal disorder, you'll need regular check-ups and monitoring. Follow your treatment plan and know the signs of an adrenal crisis.
Lifestyle tips
- Wear a medical alert bracelet or carry an emergency card
- Always carry your medications, especially if you are on steroids
- Learn to adjust stress and illness – your doctor can teach you ‘sick day rules’
Diet and exercise
Eat a balanced diet with enough salt if you have low hormone levels. Exercise as tolerated, but avoid overexertion. Talk to your doctor before starting a new diet or exercise program.
Mental health and emotional wellbeing
Living with a chronic condition can be stressful. It is normal to feel anxious or down at times. Talk to your healthcare team about your feelings – they can connect you with support.
Prevention
Most adrenal disorders cannot be prevented, but early detection helps manage them well. If you have a family history, talk to your doctor about monitoring.
Complications
If left untreated
- Adrenal crisis (a life‑threatening emergency)
- Dangerously high blood pressure or heart problems
- Bone loss (osteoporosis) due to excess cortisol
- Persistent fatigue and muscle weakness
Long-term outlook
With proper treatment and follow-up, most people with adrenal disorders can live full and active lives. Staying in close touch with your healthcare team helps keep symptoms under control.
