Some cancer patients may want to fast during the holy month of Ramadan. However, they need to take special precautions because during this time, there are changes in eating habits and daily routines, which can affect their physical condition.
Is fasting safe?
- Whether cancer patients should fast or not depends on the patient’s physical condition and the treatment. Patients undergoing chemotherapy or radiotherapy are weak, may experience nausea, dehydration, anemia, and other side effects. In this case, fasting can be risky.
- If the patient is in remission or has completed treatment, they can fast on the advice of a doctor if they are in good health.
- If the patient is in metastatic (stage four) or critical condition, the body may deteriorate further if they do not eat for a long time.
Diet and nutrition management
- Suhoor should include easily digestible carbohydrates (rice, wheat bread), protein (eggs, fish, chicken), healthy fats (almonds, olive oil), and plenty of water.
- It is important to consume protein-rich foods, adequate vegetables, fruits, and beverages during Iftar. Excess sugar and processed foods should be avoided.
- To avoid dehydration, it is necessary to drink at least 8-10 glasses of water from iftar to sahri.
Medicine and medical management
- If the patient is undergoing chemotherapy or other treatments, the doctor should be consulted to ensure the medication schedule is correct.
- Due to the side effects of chemotherapy (vomiting, diarrhea, mouth sores), it can be difficult for many patients to go without food for long periods of time.
- The timing of taking painkillers or other regular medications between iftar and sahur should be determined according to the doctor’s advice.
Rest and physical activity
- It is important for cancer patients to get enough rest, especially if they are weak.
- Light exercise or walking can be done, but excessive exertion should be avoided.
Seeking medical advice
- It is essential to consult an oncologist or physician before fasting.
- If a doctor believes that fasting may pose a health risk, then according to Islamic law, fasting is not obligatory for a sick person.
