Faint/Light-Headed
Understanding Fainting and Light-Headedness
At OneMedicine, we understand that feeling dizzy or faint can be alarming, especially when it may be related to your heart. Several underlying factors can contribute to these sensations, and addressing them promptly is key to preventing complications.
What causes fainting or light-headedness ?
Feeling faint or light-headed can happen for many reasons. It’s your body’s way of signaling that something isn’t quite right.
- Irregular heartbeats – When your heart rhythm is off, it may struggle to pump blood effectively, making you feel dizzy or faint.
- Slow heart rate – If your heartbeat is too slow (bradycardia), your brain might not get enough oxygen-rich blood, leading to light-headedness.
- A sudden drop in blood pressure – Standing up too quickly can cause a rapid dip in blood pressure, leaving you momentarily unsteady.
- Stress and strong emotions – Fear, anxiety, or shock can trigger a sudden drop in heart rate and blood pressure, sometimes leading to fainting.
If these symptoms persist, it’s important to understand what’s causing them. At OneMedicine, we take a personalised, expert-led approach to heart health—because feeling steady, strong, and in control starts with knowing what your body needs.

How are the symptoms investigated
At OneMedicine, Dr Ibrar Ahmed will conduct a rapid and rigorous evaluation to identify the underlying cause of your symptoms. Possible investigations include:
- Electrocardiogram (ECG): This test records the heart’s electrical activity to check for irregular heart rhythms or other heart-related issues.
- Wearable heart monitor: A small device, like a Holter monitor, may be worn for 24 to 48 hours to track your heart’s electrical activity over time and identify any irregularities.
- Echocardiogram: An ultrasound of the heart provides detailed images of its structure and function, helping to detect any, structural or valve abnormalities that may be contributing to your symptoms.
- Tilt table test: This test evaluates how your body responds to changes in position. By tilting you from lying down to standing up, it helps determine if sudden drops in blood pressure are causing your symptoms.
Managing dizziness & fainting
Treatment depends on the underlying cause of your symptoms, and Dr Ahmed will tailor a plan based on your specific condition:
- Medications: You may be prescribed medications to regulate your heart rate, rhythm, or blood pressure to prevent future episodes.
- Lifestyle changes: Simple adjustments like drinking plenty of water, avoiding sudden movements, and managing stress can help reduce symptoms.
- Procedures: In some cases, treatments such as a pacemaker or catheter ablation may be necessary to correct heart-related issues causing the fainting or dizziness.
- Education & monitoring: Understanding your symptoms and what triggers them is essential. Dr Ahmed will provide ongoing monitoring and advice to help you manage your health effectively.
When to Seek Help
Some symptoms need more attention. If you experience any of the following, it’s important to get checked:
- Chest pain – Especially if it happens with fainting. It could signal a serious issue.
- Shortness of breath – Could point to an underlying heart condition.
- Palpitations – A sign that your heart’s electrical system may not be working as it should.
- Fainting during exercise – May indicate a structural heart problem.
- Family history of sudden death – Could suggest a genetic heart condition that needs evaluation.
