What Your Tongue Says About Health

Your tongue can tell you a lot about your overall health. Here are some things to look for:

**

1. Color**

- A healthy tongue is pink and moist.

- A red tongue may indicate an infection, vitamin deficiency, or dehydration.

- A pale tongue can be a sign of anemia or malnutrition.

- A black tongue can be a result of smoking, drinking coffee, or taking certain medications.

**

2. Texture**

- A healthy tongue is smooth and has small, round bumps called papillae.

- A rough tongue may indicate an underlying medical condition, such as diabetes or thyroid disease.

- A swollen tongue can be caused by an allergic reaction, trauma, or certain medications.

**

3. Coating**

- A thin, white coating on the tongue is normal.

- A thick, white or yellow coating may be a sign of a bacterial or fungal infection, or it could be a sign of poor digestion.

- A black coating can be a result of smoking, drinking coffee, or taking certain medications.

**

4. Shape**

- A normal tongue is slightly rounded at the tip and tapers to the back.

- A scalloped tongue, or one that has scalloped edges, can be a sign of nutrient deficiencies or malabsorption.

- A geographic tongue is characterized by smooth, red patches that are surrounded by a white border. It is usually painless, but it can sometimes be associated with burning or tingling sensation.

If you notice any changes in the color, texture, or shape of your tongue, it's important to see your doctor to rule out any underlying medical conditions.
