Lack of energy/feeling tired all the time
Pale/yellow skin tone
Dark under eye circles
Feeling dizzy when you’re stood up/stand up too quickly
Dry mouth
Sores around the mouth and ulcers in the mouth are more likely too
Nails that are brittle
Hair loss/excessive hair fallout
Some people also get cravings for certain foods - like raw rice, or dry roti/bread etc (which offer little or no iron anyway thus reducing your iron count further)
Best thing to do is visit your GP and have a blood test done. They will let you know about possible treatments (usually ferrous sulphate tablets).
And CB - the orange and dates, do you know if there is anything on the internet verifying this, or has it been tried and tested by yourself or someone you know? I am quite interested in looking in to it further…
