Why is my mouth bitter and my tongue numb?

The tongue is a very important taste organ in the human body. Once there is an abnormality in this place, the impact will be relatively large. Bitter taste in the mouth and numbness in the tongue may be caused by disease, and some diseases are very harmful. It is necessary to find out the situation and treat it in time. A simple symptom cannot determine your condition. We need to have a full understanding of the common causes. So, what causes bitter taste in the mouth and numbness in the tongue? Let’s take a look below.

1. Poor blood circulation

A large number of patients not only have numbness of the tongue, but also purple tongue. Experts remind that when these symptoms appear, it means that there is blood stasis and poor blood circulation in your body. Under normal circumstances, when a person is in a healthy state, his tongue should be light red with a thin white coating. However, if there is venous congestion or other congestion, the tongue may turn purple and become numb. For example, slow blood flow, increased blood viscosity, twisted capillaries, increased vascular fragility, vasoconstriction and spasm, and lack of oxygen in the blood can all cause numbness of the tongue.

There is also blood clot blockage, which can also lead to poor microcirculation in the tongue and darken and purple blood vessels, resulting in the common cyanotic tongue and numbness of the tongue. These situations are generally more common when getting up in the morning, so patients must pay attention to them.

2. Too much heat

Some patients not only experience numbness of the tongue, but also have a deep purple tongue, dryness and lack of saliva. Experts remind that these are typical symptoms of excessive heat and toxicity. But if the tongue is pale purple and moist, it is due to excessive yin and coldness in the body. If the tongue is dark purple or bluish purple, it means that the blood stasis is too severe. In some patients, the blood stasis is relatively mild, and only local purple spots and petechiae on the tongue appear, which means that the blood stasis is relatively mild.

In addition to blood stasis that can cause a cyanotic tongue, patients with hepatobiliary diseases and heart disease may also experience these symptoms. According to clinical observations, most cyanotic tongue is closely related to hypoxia, fever, blood stasis, polycythemia, drinking, etc.

3. Insufficient blood supply to the brain

If a patient has symptoms such as insufficient blood supply to the brain, he or she will most likely experience numbness and cyanosis of the tongue. This is due to slow blood flow and increased blood viscosity, which can lead to local insufficient blood supply or insufficient blood supply to the brain. Therefore, experts recommend that these patients should check their blood lipids, blood sugar, blood pressure and blood viscosity as soon as possible when they experience symptoms such as tongue numbness. Once discovered, they should take lipid-lowering and blood pressure-lowering drugs as soon as possible.

In addition, tongue numbness may also be a sign of ischemic cerebrovascular disease. Once ischemic cerebrovascular disease is discovered, the patient will not only experience numbness at the tip of the tongue, but also tongue pain, local swelling of the tongue, and poor movement.
