welcome to hcm
thanks for the query
since you are feeling tired many times please try to find out your blood hemoglobin%
so do a simple blood test
for hb%,and your thyroid
profile.do you have asthma?
what is your age? if all things come normal then you can do an ECG.all these information needed for proper diagnosis.
now for time being you can take some multivitamins,more water and leafy vegetable.
