What Your Tongue Can Tell You About Your Health: 4 Symptoms You Shouldn’t Ignore

2. Red, Bald, and Glossy Tongue

Possible Cause: Vitamin Deficiency (B12, Iron, or Folate)

A smooth, reddish tongue that appears bald or shiny may be a sign of vitamin deficiency, particularly vitamin B12iron, or folate (B9). These nutrients are essential for healthy red blood cells and nerve function.

Common Causes:

  • Poor dietary intake of B12 (common in vegetarians/vegans)

  • Absorption issues like pernicious anemia or celiac disease

  • Chronic alcohol consumption

  • Long-term use of antacids or metformin

Symptoms:

  • Tongue appears red, smooth, and shiny

  • Burning sensation, especially when eating spicy or acidic foods

  • Fatigue, pale skin, or dizziness (symptoms of anemia)

Prevention and Home Care:

  • Eat iron-rich foods like red meat, spinach, and legumes

  • Include sources of vitamin B12 such as eggs, dairy, poultry, and fish

  • Consider B-complex supplements after consulting a doctor

  • Reduce alcohol intake and avoid irritating foods if discomfort persists

If symptoms include neurological changes like tingling or memory issues, seek medical attention as B12 deficiency can lead to irreversible damage if untreated.
