dizziness screening test preparation

Overview

Dizziness is a feeling of being lightheaded, unsteady, or like the room is spinning. A dizziness screening test helps doctors find out what is causing your dizziness. Preparing for these tests can make them more accurate and comfortable.

Yes, dizziness affects about 1 in 4 people at some point in their lives.

It can affect anyone, but it becomes more common with age. People with inner ear problems, low blood pressure, or certain neurological conditions may experience it more often.

Symptoms

Common symptoms

• Feeling lightheaded or faint
• Spinning sensation (vertigo)
• Unsteadiness or loss of balance
• Feeling like you might fall
• Nausea or vomiting

Symptoms in children

• Complaints of feeling funny or wobbly
• Clumsiness or falling more than usual
• Holding onto furniture for balance
• Crying or irritability with motion

Symptoms in older adults

• Sudden unsteadiness when standing up
• Fear of falling, leading to less activity
• Confusion or disorientation during dizzy spells
• Ear ringing or hearing loss along with dizziness

Causes

Main causes

• Inner ear problems (such as benign paroxysmal positional vertigo – a common inner ear issue that causes brief spinning when you move your head)
• Low blood pressure or dehydration
• Anxiety or panic attacks
• Migraine headaches
• Medication side effects

Risk factors

• Being over 65 years old
• Having an inner ear infection or history of ear surgery
• Taking multiple medications (especially for blood pressure or heart conditions)
• Low blood sugar or skipping meals
• Stress or lack of sleep

When to see a doctor

See a doctor urgently if:

• Any dizziness that comes with a head injury, seizure, or stroke-like symptoms (see emergency list above)
• Dizziness that causes you to faint or fall

Book a routine appointment if:

• Dizziness that keeps coming back and interferes with daily life
• Dizziness that lasts more than a few days without a clear cause
• You have hearing loss, ringing in your ears, or ear pain along with dizziness

Diagnosis

Your doctor will ask about your symptoms, medical history, and may do a physical exam. They often use tests to check your balance, inner ear function, and blood pressure.

Tests that may be done

• Dix-Hallpike test (you lie down and turn your head to see if it triggers vertigo)
• Videonystagmography (VNG) – you wear goggles that track your eye movements during different head positions
• Rotary chair test (you sit in a computer-controlled chair that moves gently)
• Blood pressure measurements lying, sitting, and standing
• Hearing test (audiometry)

What to expect at your appointment

For most dizziness screening tests, you will be asked to move your head and body in certain ways. The tests are not painful, but they may briefly make you feel dizzy. Wear comfortable clothes, eat a light meal beforehand (unless told otherwise), and avoid caffeine or alcohol for 24 hours before. Some tests require you to stop certain medicines, so follow your doctor's instructions exactly.

Treatment

Treatment for dizziness depends on the cause. Many cases get better on their own or with simple self-care. When needed, doctors can offer therapies or medications to manage the symptoms.

Self-care at home

• Sit or lie down immediately when you feel dizzy to avoid falling
• Move slowly when changing positions – especially when getting up from bed
• Drink enough water and eat regular meals to prevent low blood sugar or dehydration
• Avoid sudden head movements or looking up for long periods

Medical treatments

Doctors may recommend specific head exercises (like the Epley maneuver for certain inner ear causes) or prescribe medicine to reduce nausea or vertigo. Always follow your healthcare provider's advice – never take medication meant for someone else or exceed the recommended dose.

When is surgery considered?

Surgery is rarely needed for dizziness. It might be considered only if a specific problem, like a tumour or a severely dysfunctional inner ear, does not respond to other treatments.

Living with this condition

Living with dizziness can be frustrating, but most people can manage it well. Take your time with daily tasks, avoid rushing, and use handrails or a walking stick if needed. Keep your home clutter-free to reduce fall risks.

Lifestyle tips

• Get enough sleep and rest
• Reduce stress through relaxation techniques like deep breathing
• Avoid alcohol and limit caffeine, as they can worsen dizziness for some people
• Keep a diary of your dizziness episodes to share with your doctor

Diet and exercise

Eat balanced meals and stay hydrated. Gentle exercises like walking, yoga, or tai chi can improve balance and reduce dizziness over time. Avoid intense workouts that involve rapid head movements.

Mental health and emotional wellbeing

Chronic dizziness can cause anxiety, depression, or fear of falling. It's important to talk to your doctor if you are feeling worried or down. Mental health support – such as counselling or support groups – can help you cope.

Prevention

Not all dizziness can be prevented, but you can lower your risk by staying hydrated, avoiding sudden movements, and managing underlying conditions like high blood pressure or diabetes.

Screening programmes

Routine dizziness screening is not recommended for everyone. But if you have risk factors or recurring symptoms, your doctor may suggest tests. Preparing properly for these tests – like avoiding certain foods or medicines – can help get accurate results.

Complications

If left untreated

• Falls and injuries, especially fractures in older adults
• Ongoing anxiety or panic attacks
• Loss of independence and reduced quality of life
• In rare cases, missing a more serious underlying condition

Long-term outlook

For most people, dizziness improves with proper care. With the right diagnosis and treatment, you can often return to normal activities. Even if dizziness cannot be fully cured, it can usually be managed well so it does not control your life.
