Dizziness is a non-specific term used to describe a range of sensations that can make a person feel unsteady, lightheaded, faint, or as if they or their surroundings are spinning or moving. It is a common symptom that can result from various underlying causes, including issues with the inner ear, neurological conditions, cardiovascular problems, medication side effects, dehydration, anxiety, and more.

There are different types of dizziness, including:

• Vertigo: This type of dizziness gives a person the sensation that they or their surroundings are spinning or moving, even when standing still. It often occurs due to problems with the inner ear or the vestibular system, which is responsible for maintaining balance.

• Presyncope: Presyncope refers to feeling faint or lightheaded without actually losing consciousness. It can result from a temporary decrease in blood flow to the brain, such as when standing up too quickly (orthostatic or postural hypotension).

• Disequilibrium: Disequilibrium is a feeling of unsteadiness or imbalance, as if the person is going to fall. It can stem from issues with proprioception (awareness of body position) or problems with the vestibular system.

• Lightheadedness: Dizziness that does not fall into the categories of vertigo, presyncope, or disequilibrium is often classified as lightheadedness, which can manifest as feelings of floating, disorientation, or difficulty concentrating.

Dizziness can be accompanied by additional symptoms such as nausea, vomiting, sweating, ringing in the ears (tinnitus), headache, or visual disturbances. Given the wide range of potential causes, it is important for a person to consult a suitably trained healthcare professional, as a proper diagnosis is crucial for determining the underlying cause and appropriate treatment.
