2. Heavy Periods
Seeing as red blood cells are found in your blood, this means that anything that causes you to lose a lot of blood can result in anemia. This can be a problem for women who have very heavy and difficult periods that cause them to lose a lot of blood.
If you are one of these women and you notice yourself feeling very tired and out of breath, then you should speak with your physician. There are numerous potential solutions that include the use of supplementation, or potential use of oral contraceptive tablets which can help to prevent the periods and thereby prevent excessive blood loss.
