Soreness of the Tongue and Mouth
Sometimes just looking around the corners or inside your mouth can give you an idea if you are suffering from iron-deficiency anemia. Some prominent mouth signs that clearly indicates anemia include swelling or appearance of white spots on your tongue. Low levels of hemoglobin in iron deficiency anemia can cause a reduced production of a protein called myoglobin. It is present in RBCs that support your skeletal muscles, an important part of your tongue. Deficiency of myoglobin causes the tongue to become pale, sore and swollen.
