Answer:

Dear Fai,

Thank you for your question. There are several possible causes for the problem you've asked about. Red blood cells can be damaged or destroyed by a prolonged march or jog in thin shoes on a hard surface. They can also be damaged by repeated impacts on bony surfaces such the shins or the hips, such as in rugby. There are other things which can damage red blood cells besides sport. Some are metabolic problems, others involve heart valves and other mechanical causes. All of these possibilities should be discussed with a doctor, and treated by a doctor if necessary. Have you consulted a doctor about the problem of your blood cells being broken during sport? If you are seeing blood in your urine it is really important to see a doctor immediately. Because it is sometimes difficult to diagnose this problem, we are wondering if you have already talked with a doctor about it. If you have and are still having the problem, we suggest going back to talk with the doctor again.
