Cracking the Code: What Your Tongue Reveals About Your Health.
A doctor from Canada has revealed that the color, size, coating, and agility of your tongue can reveal a lot about your health. A red and smooth tongue could indicate a nutritional deficiency, while a white coating that doesn't go away could be a sign of an infection or a plaque called leukoplakia. A dry mouth could be an early sign of an autoimmune disease, and canker sores that don't go away could be an early sign of cancer. Paying attention to how you move your tongue can help you catch a neurological disorder early on.
