What Causes Dizziness? When Should You See a Doctor?
Dizziness can involve the inner ear, circulation, medications, hydration, blood sugar, or other health conditions. According to MedlinePlus, dizziness and vertigo can have many possible causes, including dehydration, sudden drops in blood pressure, certain medications, migraines, and problems affecting the inner ear.
Dizziness can feel like lightheadedness, unsteadiness, feeling faint, or a sensation that you or the room is spinning. How your dizziness feels and when it occurs can help your healthcare provider identify the possible cause.
What Does Dizziness Feel Like?
Dizziness is a symptom, not a specific disease. It may feel like:
Lightheadedness: Feeling faint or as though you might pass out
Vertigo: A spinning or moving sensation
Unsteadiness: Feeling off balance while standing or walking
Wooziness: A floating, foggy, or unusual sensation
The type of dizziness, how long it lasts, what triggers it, and whether other symptoms occur can provide important clues about its cause.
What Are the Most Common Causes of Dizziness?
Dizziness can involve the inner ear, circulation, medications, hydration, blood sugar, or other health conditions.
Dehydration
Not drinking enough fluids can cause dizziness and lightheadedness, particularly during hot weather, after exercise, or when you're sick with vomiting, diarrhea, or fever.
Sudden Changes in Blood Pressure
A temporary drop in blood pressure after standing, known as orthostatic hypotension, can cause dizziness or a feeling that you might faint.
Occasional mild episodes may happen, but frequent dizziness when standing should be discussed with a healthcare provider.
Inner Ear Problems and Vertigo
Your inner ear plays an important role in balance. When this system isn't functioning normally, you may experience vertigo—the sensation that you or your surroundings are spinning.
One common cause is benign paroxysmal positional vertigo (BPPV), which can cause brief but intense spinning after certain head movements. Other inner ear conditions may occur with hearing changes, ringing in the ears, or nausea.
Medication Side Effects
Dizziness can be a side effect of certain medications, including some used for:
High blood pressure
Depression
Seizures
Anxiety
Sleep problems
If your dizziness started after beginning a medication or changing a dose, talk with your healthcare provider. Do not stop a prescribed medication on your own unless your provider advises you to do so.
Low Blood Sugar
Low blood sugar can cause dizziness along with sweating, shakiness, weakness, or anxiety. This is particularly important for people with diabetes who use insulin or certain glucose-lowering medications.
If you have diabetes and recurring dizziness, discuss your symptoms with your healthcare provider.
Anemia
Anemia occurs when your body doesn't have enough healthy red blood cells to carry oxygen effectively. In addition to dizziness, symptoms may include:
Fatigue
Weakness
Shortness of breath
Pale skin
Your provider may recommend blood tests if anemia is a possible cause.
Migraines
Migraines don't always cause only head pain. Some people experience dizziness or vertigo, sometimes without a severe headache.
Dizziness related to migraine may also occur with sensitivity to light or sound, nausea, or visual changes.
Anxiety and Stress
Anxiety and panic attacks can cause lightheadedness, imbalance, rapid breathing, and feeling faint.
However, recurring dizziness shouldn't automatically be attributed to anxiety. A medical evaluation can help rule out other causes.
When Should You See a Doctor for Dizziness?
Consider making an appointment if your dizziness is new, keeps coming back, lasts a long time, becomes more severe, or interferes with daily activities. Mayo Clinic recommends medical evaluation for dizziness or vertigo that starts suddenly, keeps returning, lasts a long time, disrupts daily life, or has no clear cause.
See a healthcare provider if you experience:
Repeated episodes of dizziness
Dizziness without an obvious cause
New balance problems
Dizziness after starting or changing medication
Hearing changes or ringing in the ears
Frequent dizziness when standing
Dizziness associated with headaches
Symptoms that are getting worse
Your provider can evaluate your symptoms and determine whether further testing or treatment is needed.
When Is Dizziness an Emergency?
Most dizziness isn't an emergency. However, new or severe dizziness combined with certain symptoms can indicate a serious medical problem.
Call 911 or seek emergency medical care for sudden or severe dizziness accompanied by:
Weakness or numbness, especially on one side
Facial drooping
Slurred speech or difficulty speaking
Sudden vision changes or double vision
Severe or sudden headache
Chest pain
Trouble breathing
Fainting
Seizures
Rapid or irregular heartbeat
Difficulty walking or sudden loss of coordination
Persistent vomiting
Sudden dizziness or loss of balance accompanied by vision changes, facial drooping, arm weakness, or speech difficulty can be a warning sign of stroke. The American Stroke Association's stroke warning signs emphasize the importance of recognizing these symptoms and calling 911 immediately. Do not wait to see whether symptoms improve.
How Is the Cause of Dizziness Diagnosed?
Because dizziness has many possible causes, your healthcare provider will ask questions about your symptoms.
Be prepared to explain:
When the dizziness started
How long each episode lasts
Whether the room feels like it's spinning
What you were doing when symptoms began
Whether standing or moving your head triggers symptoms
What medications you take
Whether you have headaches or hearing changes
Whether you experience nausea, weakness, chest pain, or other symptoms
Your provider may check your blood pressure, balance, and other aspects of your health. Depending on your symptoms and medical history, additional evaluation may include blood tests, an electrocardiogram (ECG), hearing or balance testing, or other diagnostic tests. Imaging may be appropriate in certain situations.
What Can You Do When You Feel Dizzy?
What helps depends on the underlying cause. If you experience a mild episode:
Sit or lie down until the dizziness improves
Stand up slowly
Drink fluids if dehydration may be contributing
Avoid driving while you feel dizzy
Hold onto something stable if you feel unsteady
Keep track of symptoms and possible triggers
Consider keeping a symptom diary. Record when your dizziness starts, how long it lasts, what it feels like, and whether you experience other symptoms. This information can help your provider identify patterns.
Dizziness Treatment Depends on the Cause
There is no single dizziness treatment that works for everyone.
Treatment may involve addressing dehydration, adjusting medication under medical supervision, treating an inner ear condition, managing migraines, correcting another underlying health problem, or using specific balance exercises when appropriate.
Identifying the underlying cause is an important part of choosing the right treatment.
