This year (2026), Ramadan is expected to begin on the evening of 18th or 19th February. It is the ninth and holiest month of the Islamic calendar, a period dedicated to spiritual growth, increased devotion and worship.
If you have been diagnosed with cardiomyopathy, you may be able to fast safely from Fajr (sunrise) until Maghrib (sunset) in many cases. However, it’s important to remember that health takes precedence over fasting. If you become unwell, you can break your fast and, if you wish, make up missed fasts when your health improves.
During a fast, the body generates energy by using stored fats, carbohydrates and sugars. It can help to plan more demanding tasks earlier in the day, take short rest breaks, and focus on staying hydrated between Maghrib and Fajr.
Some people may need to adjust the timing of their medication during fasting, to avoid taking fluids during the period of sawm. If changes are needed, these may be best made gradually in the weeks before Ramadan begins.
Your community pharmacist can also be a valuable source of advice about medicines and may be able to support you with questions about medication timings.
Symptoms to look out for
For some people, changing medication timings or fasting can lead to symptoms, including:
- Swollen ankles or feet
- Shortness of breath
- Tiredness or fatigue
- Dizziness or feeling faint
- Palpitations
Our Specialist Nurse Team advises speaking with your doctor or nurse before fasting, especially if you experience any of the symptoms above, so you can discuss your desire to fast and get guidance on how to do so safely.
