I have naturally low plaelete count and just reciently it has been going down more...last blood test was at 69,000...no other abnormalities with blood, went to visit hemotologist he thinks itp, I weight train...pretty intensely, can I continue that without worry? or do I need to let up?
HiT hanks for posting your query.  There are many causes for low platelet count. But since you have consulted hematologist, and he thinks as ITP even I agree with that diagnosis.  Now coming to your query, low platelet poses risk of bleeding. In such a situation heavy exercise where the chances of external or internal injuries are high is not advisable. I advise you to do light aerobic exercise but not heavy exercise.  Any further clarification feels free to ask.  Regards.
