Iron deficiency anemia is one of the most common causes of fatigue and it's easy to prevent - eat more red meat, more beets, take a supplement or use a cast iron pan to cook more often (not the pre-seasoned kind!). There are a few measures that will show up in "normal" blood work that you can look for. These are: low normal MCV, low normal MCH, low normal MCHC and high normal RDW. MCV = mean corpuscular volume. This is the average size of your red blood cells. Smaller red cells can mean you're on your way to iron deficiency. MCH and MCHC are the average hemoglobin in red blood cells and the average hemoglobin concentration. Hemoglobin is the iron compound that carries oxygen in your blood. These are both markers of iron status and lower number can mean you're trending toward iron deficiency. Finally the RDW is a measure of the size difference between the smallest and biggest red blood cells and the higher this number the more your body is having to churn out new red blood cells to compensate for something, so higher RDW means you're also more likely to have iron deficiency anemia. None of these tests give you enough information in and of themselves, but taken together a picture starts to emerge. Your doctor probably won't pay much attention to these values if they're still in normal limits, but you can look at them to see if you need to boost your iron intake. Thanks so much for watching!
