Anemia

Anemia can be caused by a lack of iron in the body, or something more serious, such as lack of oxygen in your blood, heart problems, or even respiratory issues. If you are anemic, it must be treated by a physician and you should not train while anemic. You are inviting further problems besides the anemia itself. If it is a simple matter of lack of iron, you can supplement with red meat, which contains more iron, or small quantities of dark chocolate. If you are anemic during your menstrual cycle, then you may crave red meat or dark chocolate. Listen to your body and have some.
