Birth control pills are often prescribed by health care providers to treat certain medical conditions such as heavy periods. Because there is less menstrual bleeding when taking birth control pills, you are less likely to get anemia (low number of red blood cells, which carry oxygen from the lungs to the tissues). Since the Pill isn’t right for everyone, talk to your health care provider about whether going on the Pill would be a good choice for you. Also talk to your provider about your diet and whether you are not eating enough iron rich food. You may also need to take iron supplements to get your iron level back to normal.
