Ramadan, the sacred month of fasting observed by Muslims, is a period of deep spiritual reflection, prayer, and self-discipline. From dawn to dusk, adult Muslims refrain from food and drink, a practice that strengthens faith and resilience. However, for cancer survivors-those in recovery or post-treatment-fasting requires careful thought. Understanding its potential benefits, risks, and necessary precautions can help survivors make informed decisions about participating in Ramadan fasting.

Impact of fasting on cancer recovery

Fasting has both positive and negative effects on health, and its influence on cancer survivors depends on various factors, including treatment history, recovery stage, and overall physical condition. Cancer treatments like chemotherapy and radiation can be taxing on the body, often leaving survivors in a phase of rebuilding strength, replenishing nutrients, and supporting immune function.

Some research suggests that fasting may help reduce inflammation and improve metabolic health, which can be beneficial for long-term recovery. Additionally, many individuals experience a sense of mental clarity and spiritual fulfillment during Ramadan, which can offer emotional support during healing. However, fasting can also lead to fatigue, dehydration, and nutrient deficiencies-concerns that are especially critical for those recovering from cancer.

What are the potential risks of fasting for cancer survivors?

While fasting may have its benefits, it is not without risks. Cancer treatment weakens the body in multiple ways-affecting immunity, digestive function, and energy levels. According to Dr. Neeraj Dhingra, Consultant in Radiation and Clinical Oncology at Ruby Hall Clinic, Pune, "During cancer treatment, the body may become more vulnerable to infections, nutritional deficiencies, and fatigue. Prolonged fasting can also impair immune function, potentially putting cancer survivors at risk of relapse."

Dehydration is a major concern, particularly for those who have undergone chemotherapy or radiation, as these treatments can alter the body’s fluid balance. Prolonged fasting may also lead to drops in blood sugar levels, which can be dangerous for survivors dealing with anemia or other post-treatment side effects. Those who have recently had surgery or suffer from ongoing health complications should be especially cautious, as fasting can hinder the healing process.

Guidelines for cancer survivors considering fasting

For cancer survivors who wish to fast during Ramadan, a personalized approach is essential. Here are some key recommendations to ensure safety and well-being. Dr. Neeraj Dhingra shared some guidelines to remember for cancer survivors to consider if they wish to fast while recovering.

Consult Your Doctor: Seek medical advice before deciding to fast. A healthcare provider can assess your specific health condition, recovery status, and potential risks, guiding you on whether fasting is suitable.

Stay Hydrated: During Suhoor (pre-dawn meal) and Iftar (evening meal), drink plenty of water to prevent dehydration. This is especially important for individuals with kidney issues or digestive complications from past treatments.

Modify Your Fasting Approach: If full-day fasting is not advisable, consider alternatives like partial fasting, flexible fasting hours, or reducing food intake in a controlled manner.

Prioritise Nutrition: Opt for nutrient-rich foods such as lean proteins, whole grains, fruits, and vegetables to support your body’s healing. Avoid processed foods and excessive sugar, which can lead to energy crashes.

Listen to Your Body: Pay attention to any signs of discomfort, excessive weakness, or dizziness. If fasting causes severe fatigue or health deterioration, it is important to break the fast and seek medical help.

Fasting during Ramadan is deeply meaningful, but cancer survivors must prioritise their health while observing their faith. Consulting with doctors, modifying fasting practices if needed, and ensuring proper hydration and nutrition can help make the experience safer. By taking the necessary precautions, survivors can honor the spiritual essence of Ramadan while safeguarding their well-being.
