How Long Do You Faint For

Don't try to diagnose yourself; seek immediate medical attention if you lose consciousness.

Fainting tin can exist alarming, and information technology should be. While frequently the cause of fainting is something pocket-sized, fainting also can be a sign of a serious underlying medical business organisation. "The problem is that you tin't evaluate yourself, and you should permit a physician determine if fainting is worrisome or not," says Dr. Shamai Grossman, an associate professor of emergency medicine at Harvard Medical School, who has conducted twenty studies on fainting.

Serious causes

Fainting commonly is caused by a temporary drop in blood pressure. During that brief driblet, the encephalon does not get the blood menstruum that information technology needs—and yous lose consciousness. 1 serious crusade of this drib in blood pressure is haemorrhage, such as in the tum or intestines, or from a rupture of the torso'due south main artery, the aorta.

Several different center bug as well tin can temporarily lower claret pressure. One is heart block, in which the eye beats likewise slowly to pump enough blood. An irregular rhythm of the heart's main pumping chambers, the ventricles, can cause the middle to pump blood less efficiently. Abnormalities of a middle valve, particularly a stiffening of the aortic valve, also tin cause a temporary loss in pressure level.

All of these heart problems often produce symptoms such as palpitations (a feeling like your middle is skipping a beat or racing), shortness of breath, or chest tightness. If yous have any of these symptoms, information technology is urgent that you get to the hospital.

Another serious cause suddenly loss of consciousness is a seizure, which is an abnormality of the brain, non related to blood pressure. Some seizures produce dramatic shaking movements and loss of consciousness for longer than most fainting spells. However, other seizures tin be more subtle and difficult to recognize as seizures.

Fainting Questionnaire

Note other circumstances or symptoms that accompany the feel.

Are you feeling nauseated or airheaded?

Are you brusque of breath?

Have y'all been taking a new medication?

Are y'all eating and sleeping well?

How often have yous been feeling faint?

Call your physician, report your symptoms, and be prepared to go in for a visit.

Minor causes

Sometimes fainting is acquired by stimulation of the vagus nervus, which can briefly lower both center rate and blood pressure level. The condition is chosen vasovagal syncope (SIN-cope-ee). Information technology can occur if you strain while having a bowel move (or, for men, while passing urine), have blood drawn, go an injection, hear bad news, or even laugh too hard. These kinds of fainting episodes normally impact young people but tin can occur in older adults. Merely earlier a person faints from vasovagal syncope, he or she often feels nauseated or breaks out in a cold sweat.

You may lose consciousness for simply a moment if your blood force per unit area drops when you stand, a condition called orthostatic hypotension. Gravity temporarily pulls blood down into the veins of your legs and feet. This reduces the corporeality of blood that returns to the heart and which thereafter can be pumped to your brain. Medications, especially blood force per unit area drugs, often crusade orthostatic hypotension. So can dehydration, thyroid disorders, and neurological conditions such as Parkinson's disease.

Going to the hospital

When you arrive at the hospital, clinicians volition cheque your claret pressure and ask what medications y'all're taking. They may draw blood or perform an electrocardiogram to check for irregular heartbeats. The cause of your fainting may be axiomatic immediately. Other times, it volition require more testing. Young adults with symptoms indicating vasovagal syncope oftentimes are not hospitalized. Even so, patients ages 50 and older in the Usa often are admitted for testing, because the serious causes of fainting become more common in older people. Despite hospitalization and testing, sometimes the cause of fainting is never adamant.

What yous should do

The bottom line is that you demand medical evaluation if y'all faint—or if you feel repeatedly equally if you are about to faint. Note carefully whatever symptoms y'all remember before or after you lot pass out. Inquire anyone who may have seen yous faint depict to yous what they saw. All of this information volition help the doctor help you.
