Each time I have lunch, I notice my heart starts beating faster than normal. This happens only after eating food. I am a 53 year old female with a history of thyroid problems. I want to know the reason. Why does my heart beat so fast after eating?

Fast heartbeat after meals is called postprandial tachycardia and can occur due to increased blood flow for digestion. It may be more noticeable if meals are heavy, spicy, or high in sugar. Thyroid imbalance can also contribute to this symptom. Eat smaller, balanced meals and avoid caffeine and sugary drinks with meals. You can book a Thyroid Profile and ECG to check thyroid status and heart rhythm if it continues.
