Many people notice a sudden increase in heart rate after breaking their fast, whether with a light snack or a heavy meal, causing concern about potential heart complications.
Health studies indicate that prolonged fasting lowers blood sugar gradually, and the body adjusts its energy until Iftar. Eating high-carbohydrate or sugary meals triggers a rapid blood sugar spike, producing large amounts of insulin and activating the nervous system, which can cause temporary heart palpitations.
Eating a large meal immediately after fasting can also cause a phenomenon known as “postprandial blood shift,” where a significant amount of blood flows to the digestive system. This may lead to palpitations, warmth, and light dizziness, usually lasting only a few minutes. Persistent symptoms require medical attention.
Dehydration and fluid restriction
Extended fasting can cause dehydration, especially during summer or with insufficient water intake at Suhoor. Reduced blood volume makes the heart beat faster to compensate, increasing the likelihood of palpitations.
Caffeine, salt, and heavy meals
Caffeinated drinks like coffee and tea can trigger palpitations in sensitive individuals. Heavy or salty meals temporarily raise blood pressure and slow digestion, affecting heart rate after Iftar.
Tips to prevent rapid heartbeats in Ramadan
-
Break fast first with dates and water, then take a short break before eating the main meal.
-
Divide meals into smaller portions instead of consuming a large heavy meal.
-
Limit caffeine and sugary foods.
-
Drink 2–3 liters of water gradually between Iftar and Suhoor, avoiding large amounts at once.
