What can cause Presyncope?
Some causes for presyncope include:
- a temporary drop in blood pressure.
- dehydration.
- prolonged standing.
- intense nausea or pain.
- hypoglycemia, or low blood sugar, which may or may not be due to diabetes.
- neurally mediated hypotension, which causes your blood pressure to drop when you stand up from a sitting or lying position.
How do you classify syncope?
Syncope is classified as neurally mediated, cardiac, and orthostatic hypotension. Neurally mediated syncope is the most common type and has a benign course, whereas cardiac syncope is associated with increased morbidity and mortality.
What is a syncope workup?
Patients with cardiac syncope may be evaluated with echocardiography, Holter monitoring, stress testing, loop event recorders, or electrophysiologic studies. Other causes of syncope include orthostatic hypotension, use of certain medications, a primary neurologic disorder, and psychiatric disturbance.
Is vasovagal syncope an emergency?
Vasovagal syncope is caused by a sudden drop in blood pressure, often triggered by a reaction to something. This causes your heart to slow down for a short time. As a result, your brain may not get enough oxygen-rich blood, which causes you to pass out. Vasovagal syncope is typically not a serious health condition.
Can you drive if you have syncope?
Based on study findings, authors conclude that patients with frequent fainting episodes are safe to drive with minimal restrictions. In fact, estimated risk of car accidents is even lower in patients with vasovagal syncope than the general population.
Does syncope cause brain damage?
Vasovagal syncope is the most common cause of fainting. It happens when the blood vessels open too wide or the heartbeat slows, causing a temporary lack of blood flow to the brain. It’s generally not a dangerous condition.
What should I do after syncope?
How is vasovagal syncope treated?
- Avoiding triggers, such as standing for a long time or the sight of blood.
- Moderate exercise training.
- Discontinuing medicines that lower blood pressure, like diuretics.
- Eating a higher salt diet, to help keep up blood volume.
- Drinking plenty of fluids, to maintain blood volume.
