Fainting
Fainting Q & A
What causes fainting?
Fainting, also known as syncope, is a temporary loss of consciousness. Fainting usually occurs when you experience a sudden drop in your blood pressure that decreases blood flow to your brain, such as when you stand up too quickly.
You may also faint due to:
- Overheating
- Dehydration
- Emotional distress
- Blood sugar drop
- Use of certain medications
Fainting may also be a side effect of heart problems such as bradycardia, a heartbeat that’s too slow, or tachycardia, a heartbeat that’s too fast.
When should I schedule a medical evaluation for fainting?
Fainting once in a while when you’re too hot or stand up too quickly is usually not something to worry about. However, if you faint more frequently, you should schedule a diagnostic evaluation at Coastal Cardiology of Orange County.
You should also schedule an appointment if it takes you longer than a few minutes to regain consciousness after fainting or if you frequently experience symptoms that often occur before fainting, such as:
- Lightheadedness
- Irregular heartbeat
- Dizziness
- Sweating
- Nausea
- Weakness
- Ringing in the ears
You may also experience changes in your field of vision before losing consciousness.
The heart specialists offer comprehensive diagnostic testing, including electrocardiograms (EKGs) and echocardiograms, on-site to determine if your fainting relates to an underlying heart condition.
How is fainting treated?
Many people can prevent fainting episodes by avoiding their triggers. This may include not standing for long periods of time, drinking lots of water, and managing stress.
In some cases, you may need to add more sodium to your diet or take medications that increase your blood pressure.
If you have an underlying heart condition that causes fainting, such as an arrhythmia, you may need additional treatment to regulate your heartbeat. Treatment may involve medications or a pacemaker.
The providers at Coastal Cardiology of Orange County also work with you on lifestyle changes that can protect you from dangerous situations, such as fainting when driving or taking part in high-impact activities.
