Abdulrahman Nasiri: A Clinical Guide to Ramadan Fasting for Hematology Patients 

Abdulrahman Nasiri, Assistant Professor of Medicine and Hematology at Imam Mohammad Ibn Saud Islamic University, shared on LinkedIn:

”Just Published: A Clinical Guide to Ramadan Fasting for Hematology Patients

I am pleased to share that our latest review article, “Ramadan Fasting and Hematological Disorders: Clinical Considerations, Risks, and Management Strategies,” has just been published in Clinical Hematology International, the official journal of the International Academy for Clinical Hematology (IACH).

  • As healthcare providers, we frequently face the delicate challenge of supporting patients who wish to observe religious practices while managing chronic conditions.
  • Despite millions of Muslim patients with blood disorders worldwide, robust clinical guidelines have been historically lacking.
  • Our work aims to bridge this gap, moving beyond anecdotal approaches to lay the foundation for evidence-based care.

Key Takeaways from Our Review:

  • Risk Stratification: We propose a traffic-light framework (High/Moderate/Low Risk) to guide safety decisions, identifying who can safely fast and who should abstain (e.g., active chemotherapy or severe anemia).
  • Practical Management: We outline strategies for medication timing (switching to Iftar/Suhur dosing) and emphasize strict hydration protocols (2–3L nightly) to mitigate thrombosis and sickle cell risks.
  • Shared Decision-Making: Islamic teachings prioritize health preservation. Our goal is to empower clinicians to counsel patients with confidence using evidence-based strategies.

Moving Forward

This review is a starting point. We acknowledge the limited data and call for prospective clinical trials and larger patient cohorts to establish definitive protocols.

The foundation of care lies in shared decision-making. Islamic teachings explicitly permit breaking the fast due to illness, prioritizing health preservation.

Until we have definitive evidence, individualized risk assessment and compassionate counseling remain our cornerstone approach.

Thank you to my co-authors for this collaborative work.
