As Muslims across London and worldwide prepare for the holy month of Ramadan, expected to begin between Tuesday, February 17, and Thursday, February 19, 2026, based on moonsighting reports, understanding health considerations for fasting is crucial. While Ramadan involves abstaining from food and drink to strengthen faith, medical guidance advises against fasting for individuals who are frail, in poor health, or battling infections like flu or Covid.
Exemptions and Medical Considerations
Exemptions from fasting apply to people managing conditions such as diabetes, kidney disease, or heart disease, as well as cancer patients undergoing treatment. Pregnant and breastfeeding women are also exempt, along with those on their menstrual cycle. Medical professionals emphasize that while many individuals with heart conditions can fast safely, this depends significantly on a case-by-case basis.
Who Is Usually Safe to Fast?
Dr. Roy Jogiya, Chief Medical Advisor at Heart Research UK, explains: "Many people with stable heart conditions can fast safely, including those with well-controlled blood pressure, stable coronary heart disease, previous heart attacks with good recovery, or mild, stable heart valve disease. If you feel well and your condition is controlled, fasting is often possible with the right planning."
Before fasting, individuals with heart conditions are strongly advised to consult their doctor, especially if they have symptoms of heart failure, significant valve disease, a recent heart attack, or heart surgery. Even with a stable condition, any sudden change in symptoms should prompt a medical visit. Those requiring multiple daytime medications or diuretics may need tailored advice.
It is important not to stop or alter heart medications without medical guidance. Some medicines can be adjusted for suhoor (pre-fasting meal) and iftar (post-fasting feast), but others require careful timing. Staying hydrated between sunset and dawn is especially crucial.
Warning Signs to Watch For
Dr. Roy advises seeking medical help if experiencing chest pain, worsening breathlessness, dizziness or fainting, palpitations, or unusual fatigue during fasting. These symptoms should not be ignored. Following this, expert nutritionist Amie Leckie shares key steps for a heart-healthy Ramadan.
Nutritional Guidelines for Safe Fasting
1. Prioritize a Balanced, Nutrient-Dense Suhoor
A well-planned suhoor helps maintain energy and nutrient levels. Opt for a balanced mix of lean proteins, complex carbohydrates, and fibre to slow digestion, keep you fuller longer, and stabilize blood sugar. Include lean proteins like chicken, eggs, and legumes, and heart-healthy fats such as olive oil, avocados, nuts, and seeds. High-fibre foods release energy slowly, curbing hunger pangs.
2. Break Your Fast with Hydration and Electrolytes
Dehydration can strain the cardiovascular system. To stay hydrated:
- At iftar, start with water and electrolytes (e.g., coconut water, homemade broths).
- Spread fluid intake throughout the evening and before suhoor.
- Include water-rich foods like cucumbers, watermelon, and soups.
3. Avoid Excessive Sugar, Salt, and Ultra-Processed Foods
Diets high in sugar and salt can increase blood pressure, cause blood sugar spikes, and negatively affect cholesterol levels. Avoid high-sugar, refined carbohydrates (biscuits, sweets, pastries) and sugary drinks.
4. Maintain Overall Energy Balance and Mindful Eating
Fasting during Ramadan can improve lipid levels, lower blood pressure, and support weight loss, but overeating at iftar can undo these benefits. To maintain steady energy:
- Eat mindfully, slowly, and stop when satisfied.
- Listen to hunger cues rather than eating large portions immediately.
- Spread meals over the evening to avoid digestive strain.
5. Choose Light Exercise
Gentle movement helps keep the heart fit, aids blood flow, and regulates blood sugar without causing excessive fatigue or dehydration.
6. Focus on Sleep and Recovery
Shifting meal times and late-night worship can disrupt sleep, impacting energy, blood pressure, and heart health. Prioritize quality rest to support wellbeing. Amie suggests: "Aim for consistent sleep and wake times where possible and take short daytime naps if night time sleep is reduced."
In conclusion, Dr. Roy adds: "For those whose health may be affected by fasting, Islamic teachings recognise flexibility, where fasting is not possible." This guidance ensures that individuals can observe Ramadan safely while prioritizing their health.
