What's wrong with the brown tongue coating

A normal person's tongue is light pink. In traditional Chinese medicine, the color of the tongue coating can also be used to determine whether there are other problems in the body. Many times, improper diet can easily affect the change in tongue coating color. For example, eating foods that are too dark in color may also change the color of a person's tongue coating. Therefore, there are many factors to consider when people's tongue coating is brown. So what's the matter with the brown tongue coating?

1. A healthy tongue coating looks like this

It is light pink in color, with a clean, dry, and non-thick surface. The mouth is clean and odor-free. The tongue coating itself is smooth, and on its upper surface there are no impressions of the teeth biting.

2. The surface of the tongue coating is white

This layer of white is very thin, as if it grows on the tongue. It’s no big deal if this happens occasionally, but if it continues for several days, it means your body is getting “heaty”. Drink more water and the condition will go away on its own in a few days.

3. Thick tongue coating

The surface of the tongue coating is thick and looks like it is covered with something, and is whitish in color. At this time, if you use clean fingernails to scrape the surface of the tongue coating, you can scrape out this layer of residue-like substance. This phenomenon indicates discomfort in the gastrointestinal tract, especially the stomach.

4. Turbid surface of tongue coating

The common causes include: cold stomach, excessive tension in thoughts and emotions, poor sleep, etc. It is often accompanied by symptoms of bad breath and bitter taste in the mouth. Scraping something with your fingernails has the same effect. When talking to people face to face, you have to use chewing gum to cover it up.

5. The surface of the tongue coating is black

This color corresponds to most chronic diseases in the body. If you find any black color, get a comprehensive check-up as soon as possible. Because it corresponds to a chronic disease, most of the time it is a problem with the kidneys, so it should be taken seriously.

6. Poor stomach and intestines

The tongue coating is brown, there is constipation, and poor appetite, which is mainly caused by poor gastrointestinal function. It is recommended to eat more vegetables and fruits and develop a good work and rest routine. You can also drink some yogurt or probiotics. You can go to the hospital to check whether you have diabetes if you are thirsty and have blurred vision.
