Fainting, or the temporary loss of consciousness, can occur if your brain isn’t getting enough oxygen. Fainting may be triggered by a number of factors, including dehydration, low blood sugar, standing up too quickly, or certain medications.
Fainting happens when you lose consciousness for a short amount of time because your brain isn’t getting enough oxygen.
The medical term for fainting is syncope, but it’s more commonly known as “passing out.” A fainting spell generally lasts from a few seconds to a few minutes.
Feeling lightheaded, dizzy, weak, or nauseous sometimes happens before you faint.
Some people become aware that noises are fading away, or they describe the sensation as “blacking out” or “whiting out.”
A full recovery usually takes a few minutes. If there’s no underlying medical condition causing you to faint, you may not need any treatment.
In many cases, the cause of fainting is unclear.
Fainting can be triggered by a number of factors, including:
•fear or other emotional trauma
•severe pain
•a sudden drop in blood pressure
•low blood sugar due to diabetes
There are several types of syncope. Three common types include:
•Vasovagal syncope. Vasovagal syncope involves the vagus nerve. It can be triggered by emotional trauma, stress, the sight of blood, or standing for a long period of time.
•Carotid sinus syncope. This type happens when the carotid artery in the neck is constricted, usually after turning your head to one side or wearing a collar that’s too tight.
•Situational syncope. This type occurs due to straining while coughing, urinating, moving your bowels, or having gastrointestinal problems.
If you have a history of fainting, try to learn what’s causing you to faint so you can avoid those triggers.
Always get up slowly from a sitting or lying-down position. If you tend to feel faint at the sight of blood when getting your blood drawn or during other medical procedures, tell your doctor. They can take certain precautions to prevent you from fainting.
Lastly, don’t skip meals.
Feeling lightheaded and weak and having the sensation of spinning are warning signs of fainting. If you notice any of these signs, sit and put your head between your knees to help get blood to your brain.
When someone near you faints, you can encourage blood flow to their head by raising their feet above the level of their heart.
Alternatively, you can have them sit with their head between their knees.
Loosen tight collars, belts, and other restrictive clothing. Keep the person lying down or sitting for at least 10 to 15 minutes. A cool, quiet place is best.
A cool drink of water may also help. Learn more about first aid tips for unconsciousness.
You should call 911 or your local emergency services immediately if someone has fainted and:
•isn’t breathing
•doesn’t regain consciousness within a few minutes
•has fallen and sustained an injury or is bleeding
•is pregnant
•has diabetes
If you have no prior history of fainting and have fainted multiple times, your doctor will want to determine if an underlying medical condition is the cause.
Even people who only pass out once should at least get an electrocardiogram (ECG or EKG), which records the electrical activity of your heart.
Tell your doctor about the specific circumstances of your fainting spell, such as what you were doing and how you felt immediately before fainting.
Be prepared to give your doctor a complete medical history, including information about previously diagnosed conditions and any prescription and over-the-counter (OTC) medications you take.
Depending on the findings from a physical examination, your doctor may order additional tests.
Diagnosis typically starts with EKG. Other tests that may be used to find out why you passed out include:
Treatment for fainting will depend on your doctor’s diagnosis.
If there are no underlying medical conditions that are causing you to faint, you generally won’t need treatment and the long-term outlook is good.
