Hi guys, last week I went to donate blood. During the checkup, my blood pressure showed 89/56, which was very shocking for me because just a year back, my b.p. was 120+/90+. Of cos, i was rejected for donation because the doctor was afraid I might be suffering from low blood pressure or I might be dehydrated. I explained to him that i din not feel any symptoms of low b.p. and I did hydrate myself well enough after my morning run. (i went to donate blood at 1pm, I jogged from 5 30 to 7am). I am certain i was not suffering from any symptoms of electrolyte imbalance in my body though i do admit that I only rehydrate with water. I just wana clarify whether it is essential to rehydrate with sports drink if I were to exercise for more than 1hr+ even though i experienced no symptoms of dehydration (my diet is quite low in sodium...)
And if rehydration with sports drink/electrolyte-enhanced fluid is necessary, what kind of rehydration method is better, prepare ur own drink with electrolyte powder e.g. gatorade powder, or buy commercially prepared sports drink? Any good recommendation?
cut the jogging
from the other thread, it seems that you might not be eating enough... perhaps malnutrition...
if so, should see a doctor for it...
