I'm getting really tired when I dance or do even small heavy tasks, and I'm not sure why. I already had an ECG, and it came back normal. I'm just wondering if there's something else that could be causing this?
Feeling tired during physical activity could be due to various reasons, even if your ECG results are normal. One common reason for this could be iron deficiency anemia. I recommend you to take iron supplements like Ferrous Sulfate 325mg once daily after meals for a few months. Additionally, make sure you are staying hydrated and eating a balanced diet rich in iron and other essential nutrients. If the symptoms persist, further evaluation may be needed.
