Dizziness is a general term people use to describe feeling lightheaded, unsteady, faint, or off-balance.
Doctors use the word dizziness because people experience it in different ways, and the exact cause is not always clear at first. It can feel like spinning, floating, weakness, or feeling like you might pass out.
Dizziness is a symptom, not a diagnosis.
Doctors most often use dizziness because of common causes such as:
Low blood pressure, especially when standing
Inner ear or balance issues
Blood sugar changes
Many causes of dizziness are temporary and treatable.
People experiencing dizziness may notice:
Lightheadedness
A spinning or off-balance sensation
Trouble focusing
Symptoms that worsen when standing or moving
The feeling can last seconds, minutes, or longer depending on the cause.
This often happens when blood pressure drops briefly after standing, especially with dehydration or low fluid intake.
Dizziness can change with hydration, stress, movement, blood sugar levels, or inner ear balance.
Some common causes of dizziness don’t always show up on basic tests, especially balance or anxiety-related causes.
Feeling off-balance can trigger anxiety, which can then make dizziness feel worse, creating a cycle.
Doctors may evaluate dizziness using:
Symptom description and timing
Blood pressure checks (lying, sitting, standing)
Blood tests if needed
Balance or inner ear exams
Review of medications
Testing is guided by how dizziness feels, not just that it exists.
Dizziness is usually first evaluated by a primary care doctor.
ENT (ear, nose, and throat specialist) – for balance or inner ear causes
Cardiologist – if blood pressure or heart rhythm is involved
Neurologist – if nerve or brain causes are suspected
Specialist referral depends on symptoms and exam findings.
For many people, next steps may include:
Improving hydration
Standing up slowly
Treating inner ear issues
Managing anxiety or stress
Follow-up if symptoms continue
Many cases of dizziness improve once the cause is addressed.
