Can You Pass Out From High Blood Pressure
Don't try to diagnose yourself; seek immediate medical attention if you lose consciousness.
Fainting can be alarming, and it should exist. While often the cause of fainting is something small, fainting also tin be a sign of a serious underlying medical concern. "The problem is that you lot can't evaluate yourself, and you should allow a dr. decide if fainting is worrisome or not," says Dr. Shamai Grossman, an associate professor of emergency medicine at Harvard Medical School, who has conducted 20 studies on fainting.
Serious causes
Fainting normally is caused by a temporary drop in blood pressure level. During that brief driblet, the encephalon does not get the blood flow that it needs—and you lose consciousness. One serious cause of this drop in blood force per unit area is bleeding, such as in the stomach or intestines, or from a rupture of the body'southward main artery, the aorta.
Several unlike center problems also can temporarily lower blood pressure level. Ane is heart block, in which the centre beats likewise slowly to pump enough blood. An irregular rhythm of the heart'southward primary pumping chambers, the ventricles, tin cause the heart to pump claret less efficiently. Abnormalities of a center valve, particularly a stiffening of the aortic valve, also tin crusade a temporary loss in pressure.
All of these middle problems oft produce symptoms such as palpitations (a feeling like your middle is skipping a vanquish or racing), shortness of breath, or chest tightness. If you take whatsoever of these symptoms, information technology is urgent that yous go to the hospital.
Another serious cause of a sudden loss of consciousness is a seizure, which is an abnormality of the brain, not related to blood pressure level. Some seizures produce dramatic shaking movements and loss of consciousness for longer than about fainting spells. Nonetheless, other seizures can exist more subtle and hard to recognize as seizures.

Minor causes
Sometimes fainting is caused by stimulation of the vagus nervus, which can briefly lower both heart rate and blood pressure. The condition is chosen vasovagal syncope (SIN-cope-ee). Information technology can occur if y'all strain while having a bowel movement (or, for men, while passing urine), have blood fatigued, get an injection, hear bad news, or fifty-fifty laugh besides hard. These kinds of fainting episodes commonly affect young people simply tin occur in older adults. But before a person faints from vasovagal syncope, he or she ofttimes feels nauseated or breaks out in a cold sweat.
You may lose consciousness for merely a moment if your blood force per unit area drops when you stand up, a condition called orthostatic hypotension. Gravity temporarily pulls blood down into the veins of your legs and anxiety. This reduces the corporeality of blood that returns to the center and which thereafter tin can exist pumped to your brain. Medications, especially blood pressure level drugs, oftentimes crusade orthostatic hypotension. So can dehydration, thyroid disorders, and neurological weather such as Parkinson's disease.
Going to the hospital
When y'all get in at the hospital, clinicians volition check your blood pressure and inquire what medications y'all're taking. They may draw claret or perform an electrocardiogram to check for irregular heartbeats. The cause of your fainting may be evident immediately. Other times, it will crave more testing. Young adults with symptoms indicating vasovagal syncope oftentimes are not hospitalized. However, patients ages 50 and older in the United States often are admitted for testing, considering the serious causes of fainting go more common in older people. Despite hospitalization and testing, sometimes the crusade of fainting is never determined.
What y'all should do
The bottom line is that you demand medical evaluation if you faint—or if you feel repeatedly as if y'all are about to faint. Note carefully any symptoms you lot call back before or after you pass out. Ask anyone who may take seen yous faint describe to you what they saw. All of this data will aid the doctor help you.
