Understanding the Causes of Syncope
story by Dr. Nickie Harris-Ray
Syncope, or fainting, is a loss of consciousness that often leads to a fall. According to the American Academy of Family Physicians, it affects approximately 30 percent of adults and accounts for about three percent of emergency department visits. The overall outcome is usually good unless there is underlying heart disease. If you experience recurrent syncope but have no signs of heart disease, it is likely that you don’t have arrhythmias.
Reflex syncope is often triggered by stress or pain. Orthostatic hypotension, which is common in older adults and those with diabetes or autonomic neuropathy, happens when your body struggles to adjust blood flow upon standing, leading to fainting. Cardiogenic syncope, caused by mechanical or arrhythmic issues with the heart, usually occurs suddenly and without warning, potentially resulting in falls.
If you experience syncope, you might notice premonitory symptoms like nausea, sweating, or increased heart rate. Many episodes can be alleviated by lying down or removing the triggering factor. In contrast, cardiogenic syncope has a sudden onset, often leads to injury, lasts for a short duration, and is followed by a quick return to full consciousness.
For those with vasovagal syncope, treatment mainly involves educating oneself about the condition and avoiding known triggers. Techniques like squatting
or crossing your legs can help during episodes, and medications may reduce the frequency of syncopal episodes. Cardiogenic syncope has other specific treatments.
If you fainted once and are otherwise healthy, you probably don’t need to see
a healthcare provider. However, if you experience chest pain, confusion, or shortness of breath while fainting, you should consult a provider. Depending on the cause of your fainting, you may need a follow-up appointment two to four weeks after treatment. If a provider finds any issues with your heart’s structure or rhythm, you will likely be referred to a cardiologist.
