Dizziness can describe several different sensations. Dizziness is an impairment of spatial orientation. A dizzy spell doesn't always indicate a life-threatening condition, but it can be unnerving. Dizziness can be associated with more serious conditions, such as a stroke or cardiovascular problems. Even on its own, though, if dizziness leads to a fall, it can be dangerous.
Dizziness can occur when you’re moving, standing still or lying down. When you’re dizzy, you may feel:
Intense vertigo can make you nauseous or so unsteady you can’t drive or walk. It feels like you or objects around you are:
It’s common to experience dizziness. Almost half of people see their healthcare provider at some point because of feeling dizzy. The older you are, the more likely you are to have this symptom.
A number of conditions can cause dizziness because balance involves several parts of the body. The brain gets input about movement and your body’s position from your:
Inner ear disorders are frequently the cause of feeling dizzy. The most common causes include benign paroxysmal positional vertigo (BPPV), Meniere's syndrome and ear infections.
Benign paroxysmal positional vertigo (BPPV)
Benign paroxysmal positional vertigo (BPPV) makes you dizzy when you change your head or body position (like bending over). It usually only lasts a few seconds or minutes. This harmless condition happens when calcium crystals in your inner ear move out of place.
You may have BPPV as a result of a head injury or simply from getting older. The good news is that the treatment is easy. Your healthcare provider can lead you through a series of simple moves, called canalith repositioning procedure (CRP). These movements get the crystals back to their proper position.
Meniere’s syndrome involves having too much fluid in the inner ear. Experts aren’t sure why it accumulates. Anyone can develop Meniere’s, but it’s most common in people ages 40 to 60. If you have Meniere’s syndrome, you may also experience:
Meniere’s attacks usually happen suddenly. They can last from 20 minutes to 24 hours. Treatment methods include anti-nausea and anti-vertigo medications. Lifestyle changes may help, too, including:
If your condition doesn’t respond to simple measures, your healthcare provider may recommend more aggressive treatments. Those include injecting medication directly into the ear and surgery.
Viral or bacterial ear infections can cause inflammation (irritation) in the inner ear. The inflammation interferes with the messages your inner ear sends to your brain.
A nerve in the inner ear, the vestibulocochlear nerve, has two branches. Each branch communicates with the brain:
Ear infection treatments include medications to relieve the symptoms of nausea and dizziness. You might also need antibiotics, antiviral drugs or steroids.
Other causes of dizzy spells and lightheadedness
There are many other factors that can cause dizziness. Within the heart and vascular system, conditions that can cause dizziness include:
Brain-related conditions that can cause dizziness include:
Additional conditions that can cause dizziness include:
Treatment for vertigo and dizziness varies widely depending on the cause. Your healthcare provider may refer you to an audiologist for vestibular and balance assessment to help determine the cause for dizziness, and help determine next steps in management. If you have an ear infection, you may just need anti-nausea medication until the infection is gone. For long-term (chronic) conditions, your healthcare provider may recommend vestibular rehabilitation. It’s similar to physical therapy, with the goal of improving your balance through specific exercises.
If you have dizziness or vertigo, you should avoid several activities, including:
Take these steps to reduce your risk of falling:
If your dizziness won’t go away or keeps coming back, it’s important to talk to your healthcare provider about it. Seek emergency care if you also have any of the following symptoms:
A note from Cleveland Clinic
Your sense of balance is an intricate process that relies on many body parts. It’s easy to take it for granted until it goes haywire. Your ear, brain and heart can all affect your balance. It can take time to nail down the exact cause. But in most cases, dizziness and vertigo are symptoms of treatable conditions.
