Any have a colonoscopy? Did you miss any running days? If so, how many?
My procedure is at 2:30PM, and the doctor told me to start fasting 10AM the day prior. So I'll have to run in the morning. I'm guessing I can't run the day of the procedure.
I'm 33 year old male with low iron and anemia. Running times went from sub 80 min to half marathon to 90 min for the same overnight. Doctor is still looking for the problem. Does believe it could be from running. I have been taking about 90mg of Iron since mid Oct this year and am not feeling any better. However I have not other symptoms other than being tired constantly, low concentration, and moody.
