Circulatory problems. Conditions that affect blood flow through the body or general cardiovascular health, can create symptoms of dizziness. Common causes include anemia (decreased red blood cell numbers), hormonal changes (as with menstrual cycles and menopause), atherosclerosis, blood clots, and dehydration.
Dizziness has many possible causes, including inner ear disturbance, motion sickness and medication effects. Sometimes it's caused by an underlying health condition, such as poor circulation, infection or injury.
If the dizziness or vertigo comes in episodes that last for minutes to hours, it could be due to vestibular migraine (usually without hearing symptoms) or Menière's disease (usually with hearing symptoms), but it also can be the result of a pre-stroke (transient ischemic attack, or TIA).
Low blood pressure and low blood sugar are two common causes of dizziness and fatigue, but they are usually temporary conditions. However, unmanaged diabetes, malnutrition, anemia, and obstructive breathing disorders (e.g. sleep apnea, emphysema) can cause persistent dizziness and fatigue.
“Red flag” symptoms should alert you to a non-vestibular cause: persistent, worsening vertigo or dysequilibrium; atypical “non-peripheral” vertigo, such as vertical movement; severe headache, especially early in the morning; diplopia; cranial nerve palsies; dysarthria, ataxia, or other cerebellar signs; and ...
If the dizziness is not fleeting, eased by lying down or your balance is compromised, you should immediately visit the closest emergency department. If dizziness is accompanied by any of the following symptoms, you should also seek emergency care: Other neurological symptoms, including double vision and loss of vision.
A quick mnemonic for associated neurological symptoms is the 5 Ds: dizziness (vertigo), diplopia, dysarthria, dysphagia and dysmetria (cerebellar ataxia).
Acute cerebellar ataxia (ACA) occurs when a portion of the brain, known as the cerebellum, becomes inflamed or damaged. The cerebellum is responsible for regulating motor control and muscle coordination. Damage to this part of the brain can cause instability, loss of coordination, and persistent dizziness.
Avoid using caffeine, alcohol, salt and tobacco. Excessive use of these substances can worsen your signs and symptoms. Drink enough fluids, eat a healthy diet, get enough sleep and avoid stress. If your dizziness is caused by a medication, talk with your doctor about discontinuing it or lowering the dose.
In most cases, dizziness associated with heart problems is accompanied by other symptoms. These may include shortness of breath, swollen extremities, frequent fatigue or chest pain. In the event heart disease is suspected, you will undergo one or more tests to get to the root of your problem.
Additional symptoms of a clogged artery may include: Dizziness or weakness. Heart palpitations, or sensations of your heart racing or fluttering. Nausea or sweating.
Routine blood tests – Tests for blood sugar, blood counts, electrolytes and thyroid function help identify cases of dizziness.
Chronic dizziness can result from a number of underlying health problems, most commonly involving neurologic, vestibular and cardiac diseases. For patients who have seen a variety of specialty physicians without reaching a diagnosis, a psychiatric referral may help them find relief, researchers noted.
Dizziness by itself is not a common symptom of a brain tumor. Most cases of dizziness are related to an inner ear problem, anemia, dehydration or taking certain medications. Sometimes, being anxious or depressed can cause dizziness as well.
Vertigo can be temporary or permanent, depending on the patient. Those who have suffered a head or neck injury might experience chronic or long-term vertigo. Treatment may be a combination of medications and physical therapy. Although very rare, your ENT specialist may choose to recommend surgery.
Dizziness is often caused by illnesses that affect the inner ear, such as benign paroxysmal positional vertigo (BPPV), migraine and inflammation of the inner ear balance apparatus (called vestibular neuritis).
There are two types of vertigo, peripheral and central vertigo. Peripheral vertigo is due to a problem in the part of the inner ear that controls balance. These areas are called the vestibular labyrinth, or semicircular canals.
Dizziness and giddiness are two similar feeling with an important difference. So, it is important to avoid using them interchangeably. Dizziness is a general feeling of being off-balance. Giddiness is the feeling that you or your surroundings are moving or spinning.
While it is a common sensation, it can also be a symptom of a serious condition. When you experience severe dizziness or ongoing dizzy spells, it may be a sign of stroke or other neurological disorders.
If you have been experiencing vertigo for more than a day or two, it's so severe that you can't stand or walk, or you are vomiting frequently and can't keep food down, you should make an appointment with a neurologist.
For others, episodes of vertigo can last for several minutes or even hours. In severe cases, the unsettling sensations can occur frequently over weeks or months and make it difficult to stay balanced and carry out the tasks of daily life. Feelings of nausea often accompany prolonged episodes of vertigo.
MRI is preferred over CT due to its superiority in visualizing the posterior fossa, which is often the location for a central etiology of vertigo. MRI will rule out acute and chronic ischemic disease, cerebellopontine lesions such as vestibular schwannomas and meningiomas, as well as multiple sclerosis.
Imaging studies of the brain, and sometimes the cervical spine, are common in patients with Dizziness and Vertigo. The purpose of these studies is to identify a structural cause of dizziness such as a stroke, MS, tumor, or any number of a myriad of other disorders of the ear or central nervous system.
Dix-Hallpike Maneuver
Your healthcare provider will turn your head 45 degrees to one side. Then, you'll quickly lie on your back, with your head off the side of the table, and maintain the 45-degree head turn for at least 30 seconds. Your doctor will inspect your eyes and ask if you feel dizzy.
