Ramadan is a sacred month of reflection, prayer, and discipline. Fasting from dawn to sunset is an important spiritual practice for many, but it is equally important to remember that Islam places great value on health and wellbeing. For some individuals, fasting without medical guidance may pose serious health risks.
At Medeor Hospital, Abu Dhabi our doctors often advise patients to prioritize their health and make informed decisions during Ramadan. This blog highlights medical conditions that require special attention and situations where fasting may not be advisable without proper medical supervision.
Understanding When Fasting May Be Unsafe
Fasting involves long hours without food or fluids, changes in sleep patterns, and altered medication schedules. While healthy individuals usually adapt well, certain medical conditions can worsen due to dehydration, low blood sugar, or missed medications.
Below are some key conditions where fasting may require caution or should be avoided unless approved by a doctor.
1. Diabetes (Especially Uncontrolled Diabetes)
People with uncontrolled diabetes, frequent low blood sugar episodes, or those on insulin therapy may face serious risks during fasting. Prolonged fasting can lead to:
- Hypoglycemia (dangerously low blood sugar)
- Hyperglycemia (high blood sugar)
- Dehydration and electrolyte imbalance
Patients with well-controlled diabetes may be able to fast safely with medication adjustments, but this should always be planned with a physician.
2. Chronic Kidney Disease
Kidneys rely on adequate hydration to function properly. Fasting can increase the risk of:
- Dehydration
- Worsening kidney function
- Electrolyte disturbances
Patients with moderate to severe kidney disease, kidney failure, or those on dialysis are generally advised not to fast unless specifically cleared by a nephrologist.
3. Heart Disease and Blood Pressure Disorders
People with heart conditions such as heart failure, recent heart attacks, or uncontrolled hypertension may struggle with fasting due to:
- Fluid restriction
- Medication timing challenges
- Increased strain on the heart
Skipping or altering heart medications can be dangerous. Medical advice is essential before attempting to fast.
4. Gastrointestinal Disorders
Conditions like severe gastritis, peptic ulcers, acid reflux (GERD), and inflammatory bowel disease may worsen during long fasting hours. Common concerns include:
- Increased stomach acid
- Pain, nausea, or vomiting
- Risk of bleeding in ulcer patients
Some patients may need regular meals or medications that cannot be safely adjusted during Ramadan.
5. Pregnancy and Breastfeeding
Pregnant and breastfeeding women have increased nutritional and hydration needs. Fasting may lead to:
- Fatigue and dizziness
- Dehydration
- Insufficient nutrient intake affecting mother or baby
Islam provides exemptions in such cases, and women can make up missed fasts later or follow alternative options as advised.
6. Elderly Individuals and Frailty
Older adults, especially those with multiple medical conditions, may be more vulnerable to dehydration, falls, and medication-related complications during fasting. Reduced thirst sensation and chronic illnesses increase the risk.
7. Acute Illness or Recent Surgery
Individuals recovering from infections, fever, or surgery need adequate nutrition and fluids to heal properly. Fasting during recovery can delay healing and worsen symptoms.
Listening to Medical Advice During Ramadan
Islam emphasizes mercy and does not require fasting if it harms health. Seeking medical advice before Ramadan allows patients to understand whether fasting is safe, needs modification, or should be postponed.
