Fainting
Alternative names:
lightheadedness - fainting; passed out; syncopal episode; syncope
Home care:
Follow your health care provider's recommendations.
Susceptible individuals should avoid situations known to cause fainting. Avoid sudden changes in posture. A person who becomes lightheaded when they stand up should generate vigorous muscle activity before standing, and stand slowly.
Immediate treatment for fainting includes: - Keep the affected person lying flat or sitting forward with the head bent below the knees.
- Cool the room down or move the person to a cooler location if heat is a problem (This can be especially helpful for someone with a history of heart problems as a cause of fainting).
Call your health care provider if:
- there has been a complete loss of consciousness, especially if it occurs after a head injury or if there is no readily identifiable cause (such as a susceptible individual who faints when they have blood drawn).
- fainting is accompanied by a feeling that the room is spinning (vertigo) or any other symptoms.
- fainting occurs in a susceptible person more often than rarely.
- this is the first time a person has ever fainted.
- medication or alcohol is suspected as the cause.
- lightheadedness lasts for longer than 3 weeks.
What to expect at your health care provider's office:
The medical history will be obtained and a physical examination performed.
Medical history questions may include: - quality
- Does fainting occur with upright posture?
- Does fainting occur with a change in body position?
- time pattern
- When did the fainting occur?
- Is this the first time the person has fainted?
- Was this a single incident or did it occur more than once?
- How long did the episode last?
- aggravating factors
- Was there an apparent cause for the fainting?
- If so, what was it?
- Did it occur after exercise?
- Did it occur after coughing?
- other
- Did the person actually lose consciousness or black out?
- Were any other symptoms present before or after the person fainted?
There will be a detailed examination of the heart, lungs, and nervous system. The blood pressure may be measured in various positions.
Diagnostic tests that may be performed include: If the fainting is determined to be a simple faint, no treatment is usually recommended except as noted in the home care section. Fainting in children often becomes less common as the person grows older.
