When to seek care for dizziness

Overview

Dizziness is a general term for feeling lightheaded, faint, unsteady, or like the room is spinning (known as vertigo). It is a symptom, not a disease itself, and can have many different causes.

Yes, dizziness is one of the most common reasons people visit a doctor. Most cases are not dangerous, but it can be unsettling.

Dizziness can affect people of all ages, but it occurs more often in older adults, people with inner ear problems, and those with conditions like diabetes, heart disease, or anxiety.

Symptoms

Common symptoms

• Feeling lightheaded or like you might faint
• A spinning or whirling sensation (vertigo)
• Feeling unsteady on your feet
• Feeling like you or the room is moving when it is not
• Blurred vision or difficulty focusing
• Nausea or vomiting along with the dizziness

Symptoms in children

• Children may not be able to describe dizziness. They may seem unsteady, grab onto furniture, or refuse to walk.
• They might complain of a headache or feeling sick.
• Dizziness in children can be due to ear infections, dehydration, or migraine.

Symptoms in older adults

• Dizziness in older adults often leads to falls, which can cause serious injuries.
• It may be accompanied by confusion, weakness, or fatigue.
• Older adults are more likely to have multiple causes at once, like medication side effects, low blood pressure, or inner ear problems.

Causes

Main causes

• Inner ear problems, such as benign paroxysmal positional vertigo (BPPV) or labyrinthitis (inflammation of the inner ear)
• Low blood pressure, especially when standing up quickly (orthostatic hypotension)
• Dehydration or not drinking enough fluids
• Side effects from certain medications
• Anxiety or panic attacks

When to see a doctor

See a doctor urgently if:

• If you have any emergency symptoms (see above), call your local emergency number right away.
• If you have dizziness along with chest pain, trouble speaking, or weakness on one side – call 999 (UK) or your local emergency number.
• If you have dizziness after a head injury, even if it seems mild.
• If you cannot stand or walk because of the dizziness.

Book a routine appointment if:

• If you have mild dizziness that comes and goes for more than a few days.

Diagnosis

Your doctor will ask about your dizziness: when it happens, how long it lasts, what brings it on, and any other symptoms. They will also take your medical history and do a physical exam, including checking your blood pressure, pulse, and inner ear function.

Tests that may be done

• Blood pressure checks (lying down, sitting, and standing)
• Blood tests (to check for anaemia, infection, or other problems)
• A hearing test and balance test
• An electrocardiogram (ECG or EKG) to check the heart's rhythm

Treatment

Treatment for dizziness depends on the cause. Many cases improve on their own or with simple lifestyle changes. If a specific condition is found, treatment will target that problem. Your doctor will work with you to find the safest and most effective approach.

Self-care at home

• Get up slowly from lying down or sitting, and hold onto something steady.
• Drink enough water throughout the day, especially in hot weather.
• Avoid sudden head movements or positions that trigger your dizziness.
• Rest in a quiet, dark room if you feel dizzy.

Living with this condition

Dizziness can be unsettling, but most people can manage it with simple adjustments. Take your time with movements, use handrails, and keep your home well-lit and free of trip hazards. If you feel dizzy, sit or lie down until it passes. Let someone know so they can help if needed.

Lifestyle tips

• Move slowly when changing positions – sit up first, then stand.
• Identify and avoid triggers, such as certain head positions, bright lights, or loud noises.
• Get enough sleep and manage stress through relaxation or gentle exercise.
• Wear comfortable, flat shoes with good grip to prevent falls.

Prevention

Not all dizziness can be prevented, but you can reduce your risk by staying hydrated, moving slowly when changing positions, and treating underlying health conditions like high blood pressure or diabetes. Avoiding sudden head movements and getting enough sleep can also help.

Complications

If left untreated

• Falls and injuries, such as fractures or head injuries
• Difficulty performing everyday tasks like driving, cooking, or walking
• Increased fear of falling, which can lead to reduced activity and social isolation
• If the underlying cause is serious (like a stroke or heart condition), delay in treatment could lead to worse outcomes

Long-term outlook

The outlook for dizziness is generally very good. Most cases improve on their own or with simple treatment, and even serious causes can often be managed effectively. With proper care and support, most people can return to their normal activities.
