Scientists turn to tongue analysis to detect serious diseases
Scientists are now utilizing tongue analysis to uncover indications of serious diseases. This practice, which has been used by Chinese herbalists for over 2000 years, is now being combined with artificial intelligence to remotely diagnose illnesses. A recent study conducted by Iraqi and Australian experts found that tongue analysis accurately diagnosed health conditions in up to 94% of cases. Researchers achieved this by having 50 patients with conditions such as diabetes and anemia take pictures of their tongues, which were then analyzed by a computer programmed to detect diseases based on previous studies. This innovative solution has the potential to revolutionize the field of medical diagnosis.
1. A yellow tongue could be a sign of diabetes
A yellow-ish tongue could be an indication of diabetes. People with diabetes have high levels of sugar in their saliva, which promotes bacteria growth on the tongue. According to Healthline, there are an estimated five million people in the UK with type 1 or type 2 diabetes. Other signs of diabetes include excessive thirst, frequent urination, tiredness, itching around the genitals, and blurred vision.
2. Purple tongue may be a sign of tongue cancer
A purple tongue may be a sign of tongue cancer. According to the Oral Cancer Foundation, some tumors, including cancers of the tongue, may produce a dark red or purple color in the mouth. These tumors may bleed and not go away. Rates of mouth cancer have doubled in the UK over the last generation, with 8,864 cases being diagnosed last year. Other signs of tongue cancer include a persistent sore throat, pain when swallowing, and a burning feeling over the tongue.
3. Red tongue could indicate Covid-19
A red tongue could be a sign of Covid-19. A study conducted in Ukraine examined tongue images of 135 Covid patients using a smartphone. The results showed that 64% of mild infection cases had a pale pink tongue, 62% of moderate cases showed a red tongue, and a striking 99% of severe Covid infections had a dark red tongue. This could serve as a simple and non-invasive method to identify potential Covid-19 cases.
4. Crooked tongue could be a warning sign of a stroke
A slightly red and crooked-looking tongue can be a warning sign of a stroke. A Taiwanese study found that people experience "tongue deviation" during or after a stroke. This occurs when blood circulation is cut off to a certain part of the brain. However, not all cases of stroke display this sign, and a person may also display the sign without actually having a stroke. Other signs of a stroke include sudden numbness or weakness on one side of the body, trouble speaking, confusion, and dizziness.
5. Swollen tongue may indicate inflammation or glossitis
A puffy tongue can be a sign of inflammation, also known as glossitis. In addition to appearing swollen, inflamed tongues can also look glossy and red. This condition can be triggered by an allergic reaction, dry mouth, injury, or a nutritional deficiency like anemia. In the UK, it is estimated that 3% of men and 8% of women are anemic. Other signs of anemia include brittle nails, pale skin color, and mouth ulcers.
While most changes to the shape, color, and texture of your tongue are harmless, some require assessment and treatment by a medical professional. It's important to pay attention to any unusual changes in your tongue and consult a healthcare provider if you have concerns about your health.
