New Delhi: A new computer system created by researchers can accurately forecast diseases such as diabetes and stroke with 98 percent accuracy based on an analysis of a person’s tongue colour.
Middle Technical University (MTU) and the University of South Australia (UniSA) in Australia have created an imaging system that can diagnose various ailments, including vascular and gastrointestinal diseases, diabetes, asthma, asthma, liver and gallbladder problems, and COVID-19.
“The colour, shape, and thickness of the tongue can reveal a litany of health conditions,” said Ali Al-Naji, adjunct Associate Professor at MTU and UniSA.
“Typically, people with diabetes have a yellow tongue; cancer patients a purple tongue with a thick, greasy coating; and acute stroke patients present with an unusually shaped red tongue,” he added.

A series of studies trained machine-learning algorithms to determine tongue colour using 5,260 photos, making the breakthrough possible.
Researchers obtained sixty tongue pictures of individuals with various medical issues from two teaching hospitals in the Middle East. The AI model, for the most part, correctly identified the disease based on the tongue’s colour.
The study, published in Technologies, elucidates how the system leverages tongue colour analysis to provide real-time diagnoses, underscoring the potential of artificial intelligence to revolutionize medical procedures.
Al-Naji clarified that the artificial intelligence system is imitating a 2,000-year-old method from traditional Chinese medicine. This method uses the tongue’s thickness, colour, and form to identify medical conditions, and the AI system has been trained to replicate this process.
For instance, cancer patients often have a purple tongue with a thick, oily coating, whereas people with diabetes usually have a yellow tongue. Patients who have had a stroke generally have a strangely formed crimson tongue. A white tongue can indicate anaemia, severe COVID-19 instances are linked to a deep red tongue, and an indigo or violet tongue suggests gastrointestinal or vascular issues, as well as asthma.
The imaging system in the study made real-time predictions about health issues by using cameras positioned just 20 centimetres apart from patients to record the colour of their tongues, demonstrating its simplicity and potential for widespread use.
Professor Javaan Chahl of UniSA, a co-author, pointed out that this technology could potentially be adapted for smartphone use, significantly increasing the accessibility of illness screening and exciting the audience about the future of healthcare technology.
