7. Look at your tongue and mouth.

Have you ever paid any attention to the texture and color of your tongue? The surface of the tongue is pink and sometimes may have a thin white coating. A thick white coating might be a problem. Bacteria, food particles, and dead cells can easily lodge on the surface of the tongue and form a thick white coating on the tongue. Look for any sores, ulcers, or unusual bumps on your tongue. You can also look for any sores, ulcers, or bumps on your lips or inside your cheeks.

People with diabetes are more likely to have mouth sores. It takes longer for sores to heal when your blood sugar is high. While a white tongue is often not a symptom of a health problem, it impacts a person’s oral health and is a major cause of bad breath. When you brush your teeth, remember to also brush your tongue each time.
