Blood tests reveal high creatinine ratio, low iron saturation and low ferritin, serum. I am exhausted always struggling to be as active as I like. I am taking many supplements, including iron twice daily with vitamin C. I always feel bloated - I ve never had a big stomach but I look pregnant and feel like I am retaining fluid all over my body. I also feel itchy and can t seem to lose weight. I also have felt extremely out of breath lately and my chest feels tight. I am very active. I am a marathon runner and my pace has slowed and the long training runs are a struggle for me. Any ideas of what I am dealing with?
