Awareness
Fainting can be alarming, especially when it happens suddenly. Although many people recover quickly, fainting should never be ignored or dismissed as harmless.
Emergency responders say a fainting episode can sometimes be the body’s early warning sign that something more serious is going on, ranging from dehydration and low blood sugar to heart or neurological conditions.
ER24 Rustenburg Branch Manager and intermediate life support medic Daneel Scheepers explains that the cause of fainting (otherwise known as syncope) can range from benign triggers to conditions that need urgent medical attention, depending on the cause and context.
“The most common causes of fainting are dehydration, low blood sugar, heat exposure, emotional stress, exhaustion, sudden drops in blood pressure, and standing for long periods,” she says. “We also see fainting linked to underlying medical conditions such as heart rhythm abnormalities, infections, severe pain, or medication side-effects.”
Fainting may sometimes also be associated with more serious cardiac or neurological conditions.
When fainting becomes a medical emergency
Most fainting episodes are brief, and people recover quickly on their own. However, Scheepers warns that delayed recovery or other warning signs always require immediate medical attention.
A fainting episode should be treated as a medical emergency if the person has any of these symptoms:
- Doesn’t regain consciousness quickly
- Difficulty breathing
- Chest pain
- Severe headache
- Confusion
- Weakness
- Seizures
- Injuries from their fall.
In these situations, fainting may indicate a more serious underlying condition, such as a heart rhythm disorder, heart attack, stroke, severe infection, internal bleeding, or another medical emergency that requires urgent assessment.
Warning signs before fainting: what your body is saying
In many cases, your body gives warning signs before you lose consciousness. Recognising them can help prevent injury or escalation.
Common warning signs are:
- Dizziness or lightheadedness
- Blurred vision
- Nausea
- Sudden weakness
- Chest discomfort or palpitations
- Shortness of breath
- Severe headache
- Feeling like you’re about to black out.
“These symptoms may indicate a more serious medical issue, and you should never ignore them,” Scheepers warns.
What to do when someone faints
The first few moments after a collapse are critical. Staying calm and acting methodically makes a big difference.
The priority is safety and basic assessment, says Scheepers.
“Bystanders should first ensure the area is safe, then check if the person is responsive and breathing normally,” she explains.
“If they’re breathing, gently place them in the recovery position, which means lying them on their side with their head tilted slightly back to help keep the airway open, loosen tight clothing, and monitor them closely.”
If the person is not breathing normally or has no pulse, call ER24 on 084 124 and start CPR immediately.
Common mistakes people make
Well-intentioned responses can sometimes make the situation worse.
Common mistakes include:
- Trying to make the person stand too quickly
- Splashing water on them
- Giving food or drink before full recovery
- Crowding around the person
- Assuming they’re fine without checking for injury or warning signs.
In most cases, the safest approach is to keep the person lying down, monitor them, and wait for full recovery or medical assistance.
Fainting vs something more serious
Not every loss of consciousness is fainting. Understanding the differences can help you respond appropriately and seek medical attention sooner when needed.
“Fainting is usually brief, with quick recovery once the person is lying down,” says Scheepers. “A seizure, however, may involve jerking movements, loss of bladder control, confusion afterwards, or a prolonged recovery period.”
Cardiac-related events may have different symptoms:
- Chest pain
- Shortness of breath
- Palpitations
- Sudden collapse without warning.
If it’s not clear what caused the collapse, the person requires urgent medical care.
When fainting during exercise is a red flag
What was happening when the person fainted matters – if it was during exercise, for example, they need medical attention.
“Fainting during exercise can sometimes indicate an underlying heart condition or abnormal heart rhythm, which can be potentially life-threatening,” says Scheepers.
“Any collapse during physical activity should be medically assessed as soon as possible.”
Who is most at risk?
While fainting can happen to anyone, some groups may be more vulnerable to fainting-related complications or underlying medical causes.
These include:
- Older adults
- Those with heart conditions
- Those living with diabetes
- Pregnant women
- Individuals exposed to high heat or physical strain
- Those who are dehydrated or living with chronic illness.
What paramedics look for on arrival
When ER24 arrives on scene, they quickly check whether the fainting was brief and harmless or a sign of something more serious. “Paramedics first assess the patient’s airway, breathing, circulation, and level of consciousness,” Scheepers explains.
“Vital signs such as blood pressure, heart rate, oxygen levels, and blood glucose are checked.”
Depending on the situation, treatment may include oxygen, IV fluids, heart monitoring, or stabilising the patient before transporting them to hospital.
Serious conditions that fainting can sometimes signal
Although many fainting episodes are harmless, loss of consciousness can sometimes be linked to conditions that need urgent treatment.
These include:
- Heart rhythm disorders
- Heart attacks
- Stroke
- Internal bleeding
- Severe infections
- Epilepsy or neurological disorders
- Dangerous drops in blood pressure.
First-time fainting: when medical advice is needed
“If someone faints for the first time, it’s always advisable to seek medical advice, especially if the cause is unclear,” says Scheepers. “Even if they feel better afterwards, a medical assessment can help rule out more serious underlying conditions,” she adds.
“Many people assume fainting is always harmless, but it can sometimes be an early warning sign of a serious medical condition. It’s important to take every fainting episode seriously, especially if it happens suddenly, more than once, during exercise, or with other concerning symptoms.”
