  • I found out I’m not anemic, but I’m iron deficient. My hemoglobin is normal, but my ferritin is only at eight I start taking iron supplements, and I actually feel worse than I did before I’m more tired, more fatigued, and dizzy. I was expecting to feel better with more energy after takingiron supplements

    Just found out I have parasites and low iron. It makes perfect sense why I feel tired and lethargic.

    Thank you for your video. Do you have any insights about iron deficiency without anaemia? Similar presentation of symptoms. Interestingly, NICE guidelines (on iron deficiency anaemia) suggest a ferritin level of less than 30 micrograms/L is ‘iron deficiency’, yet ferritin levels as low as 10 micrograms/L are often categorized as ‘normal’ within GP lab ranges. I think more research is needed in this area as many suffer (from iron deficiency without anaemia) based on lab ranges without taking into consideration NICE guidelines, not to mention patient symptoms (hair loss, fatigue, palpitations, pica, insomnia etc)

    I just got my second iron infusion venofer and I feel worse than I did before. Feel like my muscles are so weak and my dizziness and balance is worse. Is this normal? Will it go away? Thank you

    Can lump in the throat sensation be caused by iron deficiency? I'm slightly iron deficiency.... I'm also highly deficient in vit d.... All my other minerals and vit levels are fine... But my throat is dying everyday Some of my symptoms like chest pain and tingling which have vanished after I have taken d3 supplements... I'm worried for my throat... I sometimes have breathing issues... Doctors are forcing me to take anti depressants
