Hi, may I answer your health queries right now ? Please type your query here...After I eat a meal, my heart beats hard and fast for about an hour or two, also I feel like it s sort of hard to breath and I feel like I can t concentrate and want to take a nap. I have had a complete cardio work up and it was normal, low blood pressure, low cholesterol, normal glucose level, and normal weight. My doctor said this was just my blood going to my stomach to digest the food. Is this harmful to my body or should I eat more smaller meals?
