Yours is low for a male but within range for thal minor. HB varies by age, gender and altitude keep in mind. Mine is usually 10 or 100 depending on where you put the dot
My HB actually drops lower when my iron deficiency is corrected...Funny how that works. If your iron is normal, check your folate and B12 vitamins. Are you eating well and sleeping enough?
And is your thyroid functioning ok? I feel pretty beat at 10 frankly but I have multiple problems and thalassemia just makes them worse.
