sounds like a lot. but maybe that is the norm for ''normal'' sedentary people. I'd have thought that for people that train and look after themselves it should be a lot lower than 5...
I work with a handful of people who are pretty much constantly ill during the entire autumn/winter
I think as an athlete who is getting recurrent colds and feeling fatigued it is not unreasonable at all to see your GP and request some routine bloods if indicated. You now know they are normal and have reassurance which is important. 4-5 colds per winter is certainly not the norm but could be a sign of your immune system not working as it should because of some source of stressor. I hope they checked your treponemal antibody though ;)
There have been a few illnesses around at work but nothung more than usual - and I spent the last 4 years around Students who aren't renowned for being disease free! Hopefully I'm just getting used to a new area. The swathes of yellow rape fields on the commute signal hayfever season is nearly upon us to take my mind off viruses!
It is the norm when you share the house with a six-year-old.
I went about 3 years without a cold, but I spent most of my time in my room playing Call of Duty
Did you check the levels yourself? GP often says ferritin levels are fine when in actual fact they are very low (for example)
Yes I have the print outs and ferritin not too bad in the wide window they give you. I am taking some feroglobin to boost Iron/B12/folic acid.
