Feeling like the room is spinning around you can be unsettling. It's more than ordinary dizziness. It's common, often very treatable, and usually not dangerous. It can sometimes signal a more serious health problem that requires medical attention.
If you're experiencing sudden dizziness, spinning sensations, balance problems, or nausea, the August Symptom Checker can help you understand possible causes and determine whether your symptoms may require medical evaluation.
What does dizziness feel like?
People use the term "dizziness" to describe several different sensations, including:
- Lightheadedness or feeling faint
- Loss of balance or unsteadiness
- Feeling weak or woozy
- A spinning sensation (vertigo)
- Feeling disconnected from your surroundings
Because dizziness can mean different things, identifying the specific sensation you're experiencing can help narrow down the cause.
8 common causes of dizziness
1. Dehydration
Not drinking enough fluids can reduce blood volume and decrease blood flow to the brain, causing dizziness, weakness, and fatigue.
Other symptoms:
- Dry mouth
- Dark urine
- Headache
- Fatigue
2. Low blood sugar
Skipping meals or going long periods without eating can cause blood sugar levels to drop, leading to dizziness.
Other symptoms:
- Shakiness
- Sweating
- Hunger
- Difficulty concentrating
3. Vertigo
Vertigo is a specific type of dizziness that creates the sensation that you or your surroundings are spinning. It's often caused by inner ear disorders such as benign paroxysmal positional vertigo (BPPV).
Other symptoms:
- Nausea
- Balance problems
- Motion sensitivity
4. Low blood pressure
A sudden drop in blood pressure, especially when standing up quickly, can cause temporary dizziness.
Other symptoms:
- Blurred vision
- Weakness
- Fainting
5. Anxiety and stress
Stress and anxiety can trigger dizziness through changes in breathing patterns, heart rate, and the body's stress response.
Other symptoms:
- Rapid heartbeat
- Shortness of breath
- Restlessness
- Feeling overwhelmed
6. Inner ear problems
The inner ear plays an important role in maintaining balance. Conditions affecting this system can cause dizziness and unsteadiness.
Other symptoms:
- Hearing changes
- Ringing in the ears
- Balance difficulties
7. Medication side effects
Certain medications can cause dizziness as a side effect, including some blood pressure medications, antidepressants, and sedatives.
Other symptoms:
- Drowsiness
- Fatigue
- Blurred vision
8. Anemia
Low red blood cell levels can reduce oxygen delivery throughout the body, leading to dizziness and fatigue.
Other symptoms:
- Tiredness
- Pale skin
- Shortness of breath
- Weakness
When should you be concerned?
Seek immediate medical attention if dizziness occurs with:
- Chest pain
- Difficulty speaking
- Sudden weakness or numbness
- Vision changes
- Severe headache
- Loss of consciousness
- Difficulty walking
- Confusion
These symptoms may indicate a serious medical condition requiring urgent evaluation.
How is the cause of dizziness diagnosed?
Healthcare providers may use:
- Medical history
- Physical examination
- Blood pressure assessment
- Blood tests
- Balance and hearing tests
- Imaging studies when necessary
The correct diagnosis often depends on understanding accompanying symptoms and identifying potential triggers.
Understanding your symptoms
Pay attention to the following factors, as they can help identify the cause of dizziness:
- When did the dizziness start? (Sudden or gradual onset)
- How long does it last? (Seconds, minutes, hours, or days)
- What triggers it? (Standing up, turning your head, physical activity, stress, etc.)
- What does it feel like? (Lightheadedness, spinning sensation, imbalance, or feeling faint)
- Are there any associated symptoms, such as headache, nausea or vomiting, hearing loss, ringing in the ears, vision changes, or weakness or numbness?
- How severe are the symptoms? (Mild discomfort versus symptoms affecting daily activities)
- Do symptoms improve with rest, hydration, or eating?
- Have you experienced similar episodes before?
Although dizziness is a common symptom, it shouldn't be dismissed if it interferes with daily activities or occurs repeatedly. Understanding the pattern of your symptoms and recognizing warning signs can help you make informed decisions about your health. If symptoms are severe, recurring, or accompanied by neurological symptoms, seek medical attention promptly.
