What causes thick white tongue coating and bad breath? Is it a disease factor?

If the tongue coating is thick and white and accompanied by bad breath, it means that the body has some kind of disease, or has eaten cold food, or has caught a cold. No matter which one it is, the harm is very serious and everyone should seek timely treatment.

1. Thick white tongue coating is a common phenomenon among people. When the tongue coating is white, we will feel that the tongue seems to become thicker, a little astringent, and sometimes accompanied by a bitter taste in the mouth. Studies have shown that the tongue coating is a layer of dirt spread on the tongue. Under normal circumstances, the substances on the surface of the tongue are constantly removed due to chewing and swallowing movements, as well as the flushing of saliva and food, leaving only a thin white layer of tongue coating. When one is sick, one eats less or only eats soft food, which reduces chewing and tongue movements, or reduces saliva secretion, and the tongue coating becomes thicker. The tongue coating of a normal person is generally thin and evenly spread on the surface of the tongue, and is slightly thicker in the middle and root of the tongue. If the tongue coating is thick and white, it means that there is a lesion in your gastrointestinal tract.

2. White tongue coating indicates that there is cold in the body. Whether you have eaten cold food or caught a cold, the tongue coating will turn white. Most people nowadays have white tongue coating, which is mainly caused by eating too much cold food or overeating chilled food. Only by eating less cold food and avoiding catching cold can we reduce the impact of cold on the internal body. When there is less cold in the body, the tongue coating will not be obviously white.

The tongue coating is white and very moist, and it appears to have an enhanced reflective property, indicating that the body is not only heavy in coldness but also heavy in dampness. Such people are prone to edema and have a lot of phlegm. When the tongue coating is white and overly moist, you must stop eating all fruits and cold foods, and never drink iced drinks. Get rid of the cold and dampness and eat more warm foods. After the cold and dampness in the body is reduced, the edema will be relieved and subside, and the phlegm will be significantly reduced.

3. If you find that your tongue coating is thick and white, you should pay attention to adjusting your diet, eat more light food, drink more water, and eat less fried food. Maintain a regular lifestyle and a good mood; take part in more physical exercise. Pay special attention to oral hygiene. Brush your teeth and rinse your mouth carefully every morning, before going to bed, and after meals. If necessary, gently brush off the tongue coating with a toothbrush or a clean towel.
