Soreness and Swelling in the Tongue or Mouth
In some cases, the indication of low hemoglobin levels can be found in the mouth. Signs include when the tongue becomes inflamed, swollen, pale or weirdly smooth. Low hemoglobin may also cause the following symptoms around the mouth. These include:
- Mouth ulcers [7]
- Dry mouth
- A burning feeling in the mouth
- Red sores at the corners of the mouth
Conclusion
A person experiencing these signs should visit a doctor. However, intake of iron-rich foods would do a lot of good and may help ease symptoms.
