Key facts

When fainting happens during illness, it is important to understand the causes, risks, and proper first aid steps. Fainting, or syncope, occurs when the brain temporarily receives less blood flow, causing a brief loss of consciousness.

• Fainting can result from dehydration, low blood sugar, infection, or sudden changes in blood pressure during illness.
• At home, ensure the person lies down safely and raises their legs to improve blood flow to the brain.
• Do not give the person anything to eat or drink until they are fully alert and able to swallow safely.
• Avoid shaking or trying to force the person to wake up; instead, check their breathing and responsiveness.
• Call 911 immediately if the person does not regain consciousness within one minute, has difficulty breathing, chest pain, severe headache, or weakness on one side of the body.
• Seek urgent care if fainting occurs repeatedly, or if it happens alongside fever, confusion, or persistent vomiting.
• Prevent fainting by staying hydrated, resting during illness, and avoiding sudden standing or rapid movements.

Recognizing symptoms and danger signs

When fainting happens during illness, it is important to understand the symptoms and know when to seek urgent help. Symptoms can range from mild to severe, and recognising danger signs can save lives.

Mild symptoms

Mild symptoms may include lightheadedness, dizziness, or feeling weak. These can often be managed safely at home by resting, drinking water, and avoiding sudden movements.

Moderate symptoms

Moderate symptoms might involve confusion, sweating, nausea, or a brief loss of consciousness. If these occur, it is best to have someone stay with the person and monitor their condition closely. Avoid giving food or drink until fully alert.

Severe symptoms and red flags

Call 911 or go to the emergency department immediately if any of the following occur:

• Fainting lasts longer than a minute or repeats frequently
• Severe chest pain or difficulty breathing
• Sudden weakness, numbness, or difficulty speaking
• Seizures or convulsions
• Unresponsiveness or difficulty waking up
• Signs of severe bleeding or injury after a fall

Never ignore these red flags. Prompt medical attention is critical to prevent serious complications.

Immediate first aid steps

When fainting happens during illness, it is important to act quickly and safely. Follow these steps to help the person while waiting for professional help or recovery.

What you can do at home or in the community

• Help the person lie down on a flat surface to improve blood flow to the brain.
• Raise their legs about 30 cm (12 inches) above heart level if possible, unless this causes pain or injury.
• Loosen tight clothing around the neck and waist to aid breathing and circulation.
• Keep the person calm and still. Encourage slow, deep breaths if they are conscious.
• Check for responsiveness and normal breathing regularly.
• If the person wakes up, encourage them to remain lying down for a few minutes before sitting or standing.

What you must avoid

• Do not give the person anything to eat or drink until they are fully alert and able to swallow safely.
• Do not shake or try to force the person to wake up.
• Avoid crowding the person; ensure they have fresh air and space.
• Do not leave the person alone if they remain weak or confused.

When to call 911 or seek urgent care

• Call 911 immediately if the person does not regain consciousness within one minute.
• Seek emergency help if the person has difficulty breathing, chest pain, severe headache, or seizures.
• Get urgent medical attention if fainting occurs repeatedly or is linked to injury, bleeding, or severe illness.

What NOT to do

• Do not wait too long to seek help if fainting occurs repeatedly or is accompanied by chest pain, difficulty breathing, or confusion.

Do NOT try to force the person to stay standing or sit upright

When to call 911 or seek urgent care

• Seek emergency care if fainting follows a head injury, chest pain, severe headache, or if the person has a known heart condition.
• Always call for help if the fainting episode is prolonged, repeated, or accompanied by seizures or confusion.

When to call 911 or seek urgent care

Knowing when to call 911 or seek urgent care is important, especially when fainting happens during illness. Some situations require immediate emergency help, while others can be managed by a family doctor or walk-in clinic.

Ongoing care and follow-up

When fainting happens during illness, careful monitoring and follow-up are important to ensure safety and recovery. After the initial fainting episode, rest in a safe, comfortable place until you feel steady. Avoid sudden movements or standing up too quickly, as this may cause another faint.

What you can do at home

• Keep hydrated by drinking water or electrolyte drinks, unless your doctor advises otherwise.
• Eat small, balanced meals to maintain blood sugar levels.
• Monitor your symptoms closely, noting any new or worsening signs such as chest pain, severe headache, confusion, or difficulty breathing.

What to avoid

• Do not drive or operate heavy machinery until you have fully recovered and your doctor says it is safe.
• Avoid alcohol or recreational drugs, which can worsen fainting or delay recovery.
• Do not ignore repeated fainting episodes or any new symptoms.

When to seek medical care

Book a follow-up appointment with your healthcare provider within a few days to discuss the fainting episode, especially if it occurred during illness. Immediate medical attention is necessary if you experience:

• Loss of consciousness lasting more than a minute
• Chest pain or palpitations
• Severe or worsening headache
• Confusion, weakness, or difficulty speaking
• Shortness of breath or difficulty breathing
• Repeated fainting episodes

For any life-threatening or rapidly worsening symptoms, call 911 or your local emergency services without delay.
