Dizziness

Also known as: Dizziness or giddiness

General information only. Anpheros does not diagnose and does not recommend treatment. Talk to a doctor or pharmacist about your situation. In an emergency, call 112 (or your local emergency number).

In short

Dizziness can cause a person to feel lightheaded, woozy, or unsteady on their feet, whereas vertigo is the feeling that they or the room is spinning. These feelings can make a person lose their balance and may be accompanied by nausea, vomiting, sweating, trouble walking, or ringing in the ears. Common causes include a sudden drop in blood pressure, dehydration, getting up too quickly, certain medicines, inner ear problems, motion sickness, migraines, or a head injury. Sudden trouble walking, dizziness, loss of balance, or lack of coordination can be signs of a stroke. Emergency help should be sought right away for these symptoms, or if sudden or severe dizziness occurs alongside vision problems, slurred speech, or weakness; call 112 in Europe or 9-1-1 in the United States.

Description

What is dizziness and vertigo?
Dizziness and vertigo are not the same thing, but they are often mixed up.
Dizziness can make you feel lightheaded, woozy or unsteady on your feet.
Vertigo is the feeling that you or the room is spinning even when nothing is moving.
These feelings may get worse when you walk, stand up, or move your head, and they can make you lose your balance. You may also have nausea, vomiting, sweating, trouble walking, or ringing in your ears.
What causes dizziness and vertigo?
Dizziness and vertigo can happen to anyone, but they are more common as you get older. As people age, they may have more health conditions and take more medicines, which increases the chance of dizziness.
Common causes of dizziness and vertigo may include:
A sudden drop in blood pressure
Dehydration
Getting up too quickly
Certain medicines
Inner ear problems, such as Meniere's disease, or benign paroxysmal positional vertigo (BPPV), the most common cause of vertigo
Motion sickness
Migraines
A head injury or ear surgery
Sometimes dizziness or vertigo is a symptom of another condition.
How is the cause of dizziness and vertigo diagnosed?
Your provider will ask about your medicines and symptoms and may do a physical exam. They may check your hearing, balance, and how you walk.
You may need an imaging test if your provider thinks you may have had a stroke or if you've had a head injury.
What are the treatments for dizziness and vertigo?
Dizziness often gets better on its own, but if it keeps happening, your provider can help you find the cause and the right treatment. Treatment depends on the cause and may include balance exercises and medicines.
Get emergency help right away if you have sudden or severe dizziness or vertigo along with vision problems, slurred speech or weakness. These may be signs of a more serious condition.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.

Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.

What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.

Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
