Swelling
You can check around or inside the mouth for the presence of iron deficiency anemia. The surrounding areas can be unusually smooth, pale, swollen, or inflamed. This is caused by the low levels of hemoglobin and myoglobin in the body. Hemoglobin is a type of protein that brings the redness to our tongue. Myoglobin is also a form of protein that supports muscle groups in our tongue. That is why iron deficiency anemia would lead to many problems with this part of the body. You can also notice some other problems, such as mouth ulcers, sore cracks, or dry mouth. [6]
