Heart Health Alert: Fasting Risks Revealed
26 Nov
Summary
- Fasting can disrupt medication timing crucial for heart stability.
- Electrolyte imbalance from fasting raises arrhythmia risk significantly.
- Heart failure patients face higher risks due to dehydration.
Fasting, a practice spanning centuries, has gained popularity for purported health benefits like weight loss and metabolic improvements. However, its impact on cardiovascular health, especially for those with heart conditions, is complex and potentially dangerous. Fasting alters crucial bodily functions including blood sugar, electrolytes, and hydration, all directly impacting heart function.
For individuals with hypertension, coronary artery disease, arrhythmias, or heart failure, fasting can lead to serious complications. These include hypoglycemia, dehydration, lethargy, fainting, and rhythm disturbances. Disruptions in medication timing, electrolyte balance, and increased stress hormones can put a significant strain on the cardiovascular system.
Cardiologist Dr. Pavankumar P Rasalkar advises caution, recommending that heart patients limit fasts to under 12 hours, maintain hydration, never alter medications without guidance, and eat nutrient-dense meals. Promptly breaking a fast if warning symptoms like chest discomfort or dizziness appear is critical for safety.
