Changes in the tongue indicate many diseases. Let us tell you how you can identify from the tongue what you are lacking or what disease you have.

Tongue is an easy way to understand the health of our body. The colour, texture, shape, and coating of the tongue can tell whether there is any disease or deficiency in the body.

A normal tongue ranges from light pink to dark pink. If its color suddenly changes, it could be a sign of a health problem.

A red tongue can be a sign of infection, fever, anxiety or a vitamin B deficiency. A pale tongue is associated with anemia or a lack of nutrition in the blood. A blue or purple tongue can mean poor blood flow or heart-lung problems. A yellow coating can indicate digestive or liver problems.

A light coating on the tongue is normal but if the coating becomes thick, coloured or patchy, it is a sign of a health problem. A white coating is associated with oral thrush or dehydration. A yellow or green coating may be a sign of bacteria or a digestive problem. A black and hairy tongue is caused by poor hygiene, smoking or medications.

If the tongue looks swollen or larger than normal, it could be a sign of allergy, infection or hormonal problem. The absence of bumps on the tongue indicates a deficiency of vitamin B or iron.

If teeth marks are visible on the edges of the tongue, it is called scalloped tongue. This can be a sign of stress, thyroid problems or water retention in the body.

Red spots, sores or lumps on the tongue can be a symptom of infection, injury or serious illness. Long-lasting spots or swelling should not be ignored as it may be associated with diseases such as cancer.
