9 Things You Didn’t Know About Iron Deficiency Anemia

Iron Deficiency Anemia (IDA) is more common than you may realize. Here's what you need to know about it to start a discussion with your doctor — especially if you experience heavy uterine bleeding (HUB).

IDA, which is the most common form of anemia, is a condition that interferes with the formation and function of red blood cells.

The more you know about IDA, the easier it is to recognize. Here are nine things you might not have known about the condition:

1. Around 6.5 million Americans have IDA and some might not even know it.

2. Approximately 20% of women in the United States who are 16 to 49 years old (childbearing age) have IDA.

3. Fatigue, weakness, dizziness, and shortness of breath are all common symptoms of IDA.

4. Pica, which is the craving of nonfood items such as ice or dirt, can also be a symptom.

5. However, not everyone with IDA has symptoms.

6. According to a Harris Poll study, 51% of women surveyed had experienced an IDA symptom within the past 12 months but 31% of these women hadn’t discussed it with a healthcare provider.*

7. The same study found that 32% of the women who didn’t talk to a healthcare provider thought their symptoms weren’t serious enough to bring up.*

8. Having a family history of IDA does not mean that you’re more likely to develop IDA.

9. But IDA can be caused by HUB, which affects approximately 1 in 4 women.

If you have HUB and think you might also have IDA, you should talk to your healthcare provider. You can learn more about the connection between HUB and IDA at
