Feeling dizzy can mean lightheadedness, spinning, unsteadiness, or feeling as though you might faint. Some causes are relatively minor, while others need prompt medical attention. Understanding the pattern can help you know what to do next.
Dizziness has many possible causes. New, repeated, severe, or unexplained dizziness should be discussed with a healthcare professional. Do not stop, start, or change prescription medicines based on this article.
Sudden dizziness can sometimes occur with a stroke or another serious medical problem. Get emergency help when dizziness occurs with symptoms such as:
Dizziness is a broad term. Identifying the sensation that comes closest to what you are feeling can make a conversation with your healthcare professional more useful.
Balance depends on several systems working together: the inner ear, eyesight, nerves, muscles, brain, blood vessels, and heart. Medications can affect balance as well.
A problem in any one of these areas can make someone feel dizzy or unsteady. Recurring symptoms deserve attention because dizziness can also increase the chance of falling.
The trigger, timing, length of the episode, medications you take, and other symptoms occurring at the same time all help narrow down what may be happening.
Symptoms can overlap, so a healthcare professional may need to review your medical history, medications, blood pressure, balance, hearing, heart rhythm, or other factors before identifying the cause.
BPPV commonly causes brief episodes of spinning after certain head movements such as rolling over in bed, looking upward, bending down, or getting in and out of bed.
Treatment often involves canalith-repositioning techniques such as the Epley maneuver after the condition has been appropriately evaluated.
Orthostatic hypotension is a drop in blood pressure after standing from a sitting or lying position.
Dehydration, medications, prolonged bed rest, and several medical conditions can contribute.
Not having enough fluid in the body can reduce circulating blood volume and contribute to lightheadedness, fatigue, or weakness.
People with heart failure, kidney disease, or prescribed fluid restrictions should follow their healthcare team's instructions.
Prescription medicines, over-the-counter products, and combinations of several medications can sometimes contribute to dizziness or unsteadiness.
Do not stop a prescription medication on your own. Ask your doctor or pharmacist to review your medication list.
Abnormal heart rhythms, heart valve disease, heart failure, and other circulation problems can sometimes cause lightheadedness, weakness, or fainting.
Stroke, Parkinson's disease, neuropathy, and other neurological problems can affect balance and coordination.
Sudden dizziness accompanied by weakness, numbness, trouble speaking, vision changes, or loss of coordination should be treated as a possible stroke emergency.
BPPV is not the only balance disorder involving the inner ear. Other conditions can produce vertigo, nausea, hearing symptoms, ear pressure, or persistent unsteadiness.
Eyesight, lower-body strength, reflexes, sensation in the feet, and reaction speed all contribute to staying steady.
Problems in several of these areas at the same time can make dizziness harder to manage and make falls more likely.
Timing does not diagnose the cause, but it can provide useful information for your healthcare professional.
Your first goal is to avoid a fall while you determine whether the symptoms require urgent medical attention.
The right treatment depends on the cause, but several everyday strategies can help improve safety while the cause is being evaluated.
Pause after sitting up and again after standing before beginning to walk, especially if standing tends to trigger lightheadedness.
Regular fluid intake can help when dehydration contributes. Follow your clinician's advice if you have kidney, heart, or other conditions requiring fluid restriction.
Bring prescription medicines, over-the-counter products, vitamins, and supplements to a medication review with your doctor or pharmacist.
Appropriate strength and balance work may help depending on your health, abilities, and the cause of the dizziness.
If gentle movement is appropriate for you, review our Tai Chi for Seniors guide for seated and supported options.
You can also use our printable chair Tai Chi exercises when you want a routine you can keep nearby.
Even temporary dizziness can become dangerous near stairs, loose rugs, dark hallways, or slippery bathrooms.

Frequent, recurring, or unexplained dizziness should not simply be accepted as part of getting older.
Write down how the sensation felt, when it started, what you were doing, how long it lasted, what triggered it, and what other symptoms occurred.
Check the statements that apply and take the list to your next medical appointment. This is not a diagnostic test.
These answers provide a starting point. Recurring or unexplained symptoms should be discussed with a healthcare professional.
Dizziness can become more common because of medications and medical conditions, but recurring dizziness should not automatically be dismissed as normal.
One possibility is orthostatic hypotension, a drop in blood pressure after standing. Dehydration, medications, prolonged bed rest, and medical conditions can contribute.
Brief spinning triggered by head movements can occur with BPPV, a common inner-ear balance disorder. Other conditions can produce similar symptoms.
Yes. Several prescription and over-the-counter medicines can cause dizziness, sedation, blood-pressure changes, or unsteadiness. Do not stop prescription medicine without medical guidance.
Yes. Dehydration can contribute to lightheadedness. People with medically prescribed fluid restrictions should follow their healthcare professional's advice.
Sudden dizziness or loss of balance can occur with stroke, especially with weakness, numbness, speech difficulty, vision changes, severe headache, or sudden trouble walking. Call 911 when stroke is suspected.
This guide is educational and is informed by established medical organizations. Individual symptoms and medical needs differ.
Sometimes the explanation is relatively straightforward, such as positional vertigo, dehydration, or a medication effect. Other times, dizziness may be connected to blood pressure, the heart, the nervous system, or another medical condition.
Pay attention to the pattern, protect yourself from falls, and have recurring or unexplained symptoms evaluated instead of guessing at the cause.
