Could Your Symptoms Be Related to Low Iron?

This Iron Deficiency Checklist helps you review common symptoms and risk factors that may be linked with low iron, such as fatigue, shortness of breath, heavy periods, and recent blood loss.

Your score is not a diagnosis. It is a simple checklist that can help you organize what you are noticing and understand which blood tests are often used to check iron status.

Use your result as a starting point for a conversation with a healthcare professional, especially if symptoms are new, getting worse, or affecting daily activities.

This checklist is for general education only and is not a diagnosis, treatment plan, or substitute for care from a qualified healthcare professional.

An Iron Deficiency Checklist result shows whether your selected symptoms and risk factors create a lower, moderate, or stronger signal for possible low iron. It does not diagnose iron deficiency or anemia. The result can help you decide what symptoms to track and what questions to ask a healthcare professional.

Common signs of low iron can include fatigue, weakness, shortness of breath with usual activity, pale skin, feeling unusually cold, restless legs, brittle nails, and hair shedding. Some people also have dizziness, headaches, or fast heartbeat. These symptoms can come from many causes, so blood tests are often needed.

Blood tests used to check for iron deficiency often include ferritin, hemoglobin, complete blood count, serum iron, total iron-binding capacity, and transferrin saturation. Ferritin can reflect stored iron, while hemoglobin and CBC help show whether anemia is present. A clinician interprets these results with your symptoms and history.

Heavy menstrual bleeding can contribute to low iron because blood loss removes iron from the body. Over time, this may lower iron stores and sometimes lead to iron-deficiency anemia. If periods are very heavy, changing, or causing fatigue or shortness of breath, it is worth discussing with a healthcare professional.

Diet can contribute to iron deficiency when iron intake is low or when a vegetarian or vegan diet is not planned to include enough iron-rich foods. Plant-based iron is absorbed differently than iron from meat. Vitamin C can support absorption, while some foods and drinks may reduce absorption when taken with iron-rich meals.

You should not start iron supplements only because of a checklist score. Too much iron can cause side effects and may be unsafe for some people. A healthcare professional can help decide whether testing is needed and whether iron supplements are appropriate based on your results and health history.

Seek urgent care for chest pain, fainting, severe shortness of breath, rapid heartbeat with weakness, black or bloody stools, heavy bleeding, or extreme tiredness that feels sudden or severe. These symptoms can have serious causes. A checklist cannot determine whether they are due to iron deficiency or something else.
