Dizziness: Causes and Treatment
Dizziness means feeling lightheaded, unsteady, or like your surroundings are spinning. Common causes include inner ear problems, dehydration, low blood pressure, low blood sugar, and some medicines. Most cases are not serious, but dizziness with chest pain, severe headache, or weakness needs emergency care.
What Is Dizziness?
Dizziness is a general term for feeling lightheaded, faint, unsteady, or like the room is spinning. It is very common and usually not dangerous. Doctors often describe three types: vertigo (a spinning feeling), lightheadedness (feeling faint), and unsteadiness (feeling off balance). Noticing which type you feel can help identify the cause.
Common Causes
Many everyday problems can cause dizziness. Most cases are mild and settle on their own. Common causes include:
- Inner ear problems, such as benign paroxysmal positional vertigo (BPPV) or ear infections
- Dehydration or overheating
- Low blood pressure, especially when standing up too quickly
- Low blood sugar from skipping meals
- Side effects of medicines, such as blood pressure pills or sedatives
- Anxiety, stress, or fast, shallow breathing
- Anemia (too few red blood cells)
- Heart rhythm problems, which are less common but need medical care
How Dizziness Is Treated
Treatment depends on the cause. Drinking fluids helps dizziness linked to dehydration. A trained health professional can treat BPPV with simple head-positioning maneuvers, such as the Epley maneuver. If a medicine is the cause, a doctor may adjust the dose or change the medicine. Balance exercises, called vestibular rehabilitation, can help ongoing inner ear problems.
Self-Care at Home
Simple steps can keep you safe and reduce dizziness:
- Sit or lie down right away when you feel dizzy, and get up slowly
- Drink water regularly, especially in hot weather or when active
- Eat regular meals to keep your blood sugar steady
- Avoid sudden head movements, such as looking up quickly
- Do not drive or use machines while dizzy
- Use good lighting and handrails at home to prevent falls
Self-check steps
1Describe the feeling
Decide whether you feel lightheaded, unsteady, or like the room is spinning. A spinning feeling points more toward the inner ear, while faintness can point to blood pressure, hydration, or heart causes.
2Note timing and triggers
Write down when dizziness happens, such as when you stand up or turn your head. Also note how long each episode lasts.
3Check fluids and food
Ask yourself whether you have been drinking enough water and eating regular meals. Dehydration and low blood sugar are common and easily fixed causes.
4Review your medicines
Check the labels of your medicines and supplements for dizziness as a side effect. Do not stop a prescribed medicine without talking to a doctor.
5Watch for red flags
Check for chest pain, weakness, slurred speech, severe headache, or fainting. If any of these appear, call your local emergency number right away.
When to seek medical help
Call your local emergency number right away if dizziness occurs with chest pain or pressure, shortness of breath, fainting, a severe or sudden headache, weakness or numbness on one side of the body, trouble speaking, double vision, confusion, or trouble walking. These can be signs of a heart problem or stroke. Contact a doctor promptly if dizziness is severe, lasts more than a few days, keeps coming back, follows a head injury, or interferes with your daily life.
