12 Hidden Signs of Iron Deficiency You Shouldn't Ignore

Swelling and Soreness of the Tongue

An inflamed or swollen tongue, known as glossitis, can be a sign of iron deficiency. This condition can cause the tongue to appear smooth, swollen, and unusually red, often accompanied by soreness or pain. Iron is essential for the production of myoglobin, a protein in muscle cells, including those in the tongue. A deficiency can lead to muscle weakness and changes in the tongue's appearance and function. Addressing iron deficiency can help alleviate these oral symptoms and improve overall oral health.

Unusual Cravings for Non-Food Substances

Pica is a condition characterized by cravings for non-food substances such as ice, clay, dirt, or paper. While the exact cause of pica is unknown, it has been linked to iron deficiency. These cravings can be harmful and lead to further nutritional deficiencies or health issues. Recognizing and addressing pica is important, as it often indicates an underlying deficiency that needs to be corrected. Increasing dietary iron intake or supplementation can help reduce these unusual cravings and restore normal eating behaviors.
