Feeling faint and dizziness

Feeling faint and dizziness are common symptoms that may appear as weakness, loss of balance, a light-headed feeling or even a brief loss of consciousness. The sensation is often related to situations where blood pressure drops suddenly, such as when standing up quickly, being in hot environments or under stress. Typically, in young and otherwise healthy people, feeling faint is harmless and passes quickly, and does not require special examinations or treatment.

The most common causes in Finland are so-called reflex faints, low blood pressure, dehydration, standing up too quickly and sometimes stress or anxiety. Dizziness may also be related to inner ear problems, such as benign positional vertigo, or more rarely as a symptom of illness. Alcohol use and its effects can also cause dizziness and faintness.

The symptom should be taken seriously if it is associated with a severe loss of consciousness, convulsions, chest pain, breathing difficulties, changes in heart rate, numbness, or if fainting occurs without warning signs. Persistent dizziness, sudden hearing loss or other unusual symptoms are also reasons to seek assessment by a healthcare professional.
