Fainting Symptoms
Fainting or Syncope
Fainting or Syncope (medical term) is defined as the loss of consciousness, lasting for a few seconds or minutes. There is no awareness of the surrounding environment as well as oneself. Most individuals also refer to it as “passing out”. Loss of consciousness is usually followed by a state of complete wakefulness and temporary muscle weakness. The primary pathology of fainting is the temporary reduction in blood supply and oxygen to the brain.
A few warning signs and symptoms may appear before you faint:
- Dizziness
- Vomiting
- Nausea
- Blackouts
- Feeling lightheaded
- Sweating
- Blurred vision
- Changes in vitals like blood pressure, heart rate, and breathing rate
What are the causes of Fainting?
Fainting occurs due to reduced blood and oxygen supply to the brain and is a frequent symptom of related diseases or triggers listed below:
- Mechanical causes: Straining during coughing, sneezing, urinating, pooping, etc.
- Cardiogenic causes: Irregular heartbeat and blood pressure fluctuations can cause heart function abnormalities and lead to fainting.
- Carotid sinus: Compression of the carotid artery near the neck can cause fainting.
- Orthostatic hypotension: Getting up suddenly from sitting can cause fainting due to a sudden drop in blood pressure, known as orthostatic hypotension.
When should you consult a doctor if you have Fainting?
When you experience fainting episodes, you must consult a medical professional in the following cases:

What are the diagnosis and treatment options for Fainting?
Establishing a diagnosis based on the cause of fainting is essential to prevent future episodes. A detailed history of what led to fainting, symptoms, and how many times you have experienced will be obtained by an attending physician. Laboratory tests such as an electrocardiogram (ECG), electroencephalogram (EEG), blood sugar, etc., may be conducted based on the history provided by the individual or caretaker.
Once the cause of fainting is established, medical treatment may be initiated in the form of medicines for the cause of fainting and appropriate therapy.
One usually revives from a fainting episode within a few seconds to minutes. If you know someone who has a history of fainting, you must call for help and initiate Cardiopulmonary Resuscitation (CPR) in case of prolonged fainting. You are advised to take help from a medical professional before beginning any treatment procedure.
Conclusion
Fainting is the temporary loss of consciousness lasting for seconds to minutes. Associated with dizziness, nausea, vomiting, blackouts, etc., just before fainting, one may experience transient muscle weakness and memory loss once consciousness is regained. Diagnosis and treatment are based on the cause of fainting.
If you or anyone you know is experiencing frequent or unexplained fainting episodes, seek medical help immediately for proper diagnosis and further treatment.
