Other common triggers of vasovagal syncope include:
- Standing for long periods, which can drive blood into the legs of a person.
- Exposure to too much heat can also be a trigger.
- Aside from the sight of blood, having blood drawn or even the sight of needles can also be a trigger.
- Intense fear, especially fear of bodily injury, can also be a trigger.
- Momentarily holding your breath and exerting effort against a closed glottis (found in the throat), called the valsalva maneuver, can induce vasovagal syncope. This may happen while inducing bowel movements or during fits of coughing.
The triggers are not limited to these as there are other things that can result in a person losing consciousness because of the lack of blood in the brain.
When Should You See a Doctor?
So, when should you see a doctor if you suspect that you are suffering from vasovagal syncope? If you have already been diagnosed with the condition, there is no need to see your doctor after each episode. Though you need to check in with your doctor if you are having more frequent episodes or if you notice that the episodes are happening because of new triggers.
If you have never had fainting episodes before and you suddenly suffer from one or several, it’s best to seek medical help immediately.
There are other medical conditions that can make you prone to fainting and those include:
Your doctor will examine you and conduct tests to eliminate the possibility that you are suffering from any of these conditions.
Some medications can also cause you to faint but don’t stop taking your medicines because you suspect it is causing you to faint. Let your doctor confirm it first.
How is it Diagnosed?
As with other diagnoses, your doctor will start with a general check-up and a study of your medical history. They might require an ECG or an EKG to check your heart rhythm. Other tests may include:
- Exercise stress test
- Portable Holter monitor
- Tilt-table test
These tests can confirm if you actually have vasovagal syncope or if some other condition is to blame for your fainting.
Because fainting can be caused by other factors, you need to see your doctor if you suddenly experience fainting spells. Vasovagal syncope is not a dangerous condition but there are other disorders that may have similar symptoms. It’s important that you learn as early as possible.
