Dizziness is a sensation of feeling lightheaded, faint, weak, unsteady, or off-balance. Some people also use the word dizziness to describe a spinning sensation in themselves or their surroundings. This spinning sensation is called vertigo, which is a specific type of dizziness.

Dizziness is common and can have many possible causes. It may be temporary and improve on its own, but sudden, severe, repeated, or unexplained dizziness should be evaluated by a healthcare professional.
What Does Dizziness Feel Like?
Dizziness can feel different from person to person. Common sensations include:
Feeling lightheaded or as though you might faint
Feeling unsteady or off-balance
Feeling weak or woozy
Feeling as though you or the room is spinning
Having difficulty maintaining balance
Experiencing nausea or vomiting
Dizziness may become more noticeable when standing up, walking, or moving your head, depending on its cause.
What Causes Dizziness?
There are many possible causes of dizziness. Common causes include dehydration, a sudden drop in blood pressure, standing up too quickly, motion sickness, migraine, certain medicines, and inner-ear problems.
The inner ear plays an important role in maintaining balance. Conditions such as benign paroxysmal positional vertigo (BPPV) and Ménière's disease can affect the balance system and cause vertigo or dizziness.
Anxiety and other health conditions can also contribute to dizziness. Because there are many possible causes, factors such as the type of sensation, how long it lasts, what triggers it, and other symptoms can help a healthcare professional determine the underlying cause.
Dizziness vs. Vertigo
Although the terms are sometimes used interchangeably, dizziness and vertigo are not exactly the same.
Dizziness is a broad term that can describe sensations such as lightheadedness, weakness, or unsteadiness. Vertigo specifically involves the sensation that you or your surroundings are moving or spinning when there is no actual movement.
In other words, vertigo can be considered a specific form of dizziness rather than a completely separate condition.
What Can Help With Dizziness?
What helps depends on the underlying cause. If you feel dizzy, sit or lie down until the sensation passes to reduce the risk of falling. When getting up, move slowly and carefully.
Staying adequately hydrated may help when fluid loss is contributing to dizziness. However, persistent or unexplained dizziness should not be treated only with home measures. A healthcare professional can assess the symptoms and determine whether further testing or treatment is needed.
When Is Dizziness an Emergency?
Sudden or severe dizziness accompanied by other serious symptoms requires urgent medical attention. Warning signs can include weakness or numbness, trouble speaking, difficulty walking, vision changes, severe headache, chest pain, breathing difficulty, fainting, or confusion.
These symptoms can sometimes occur with serious medical conditions, so prompt evaluation is important.
Conclusion
Dizziness is a sensation of feeling lightheaded, faint, unsteady, or sometimes as though you or your surroundings are spinning. It can have many causes, ranging from dehydration and motion sickness to medication effects, blood-pressure changes, migraine, or inner-ear conditions.
Understanding the type of dizziness, its duration, triggers, and accompanying symptoms can help healthcare professionals identify the possible cause and recommend appropriate care.
