Why are the blood vessels under the tongue purple and black?

The tongue is an important organ in the oral cavity. Some of its symptoms can accurately reflect a person's physical condition. For example, if the blood vessels under the tongue appear purple or black, it means that the body is invaded by cold evil, and the blood is not flowing smoothly and there is blood stasis. Experts say that if this is the only symptom and there are no other abnormalities, no treatment is needed, but if the symptoms become more and more severe, you should pay attention.

1. What is the reason for the purple and black blood vessels under the tongue?

The purple and black blood vessels under the tongue indicate sublingual varicose veins, which are caused by the invasion of cold evil, leading to poor blood circulation and finally blood stasis. If there are no other symptoms, it is recommended to observe for a period of time. If the sublingual varicose veins do not interfere and do not continue to develop more seriously, then there is no need to take medicine.

Other common symptoms related to tongue

1. Purple tongue: The blood is too thick

When the human body contains a large amount of old waste, lacks water in the body, or suffers from hyperlipidemia, the viscosity of the blood will increase and cause poor blood circulation, resulting in a cyanotic reaction on the tongue.

People with a purple tongue usually have symptoms such as stiff shoulders, back pain, and dysmenorrhea. If purple spots appear on the tongue, it means that blood vessels somewhere in the body are blocked, causing blood circulation to be obstructed.

The tongue coating is thick and the surface of the tongue is almost invisible. It may be caused by gastrointestinal dysfunction caused by factors such as overeating. In addition, the tongue coating will also thicken when a major illness occurs. A tongue coating that is so thin that it is almost invisible also indicates physical weakness or an allergic constitution.

A tongue that is as smooth as a mirror and has no tongue coating is a precursor to peptic ulcer; a rough tongue indicates nutritional deficiencies and anemia caused by poor iron absorption.

2. Red tongue: excessive heat accumulation

If the entire tongue looks very red, it means that there is too much heat accumulated in the body and the body is in a state of lack of water, which is often accompanied by symptoms of fever in the head or whole body. Excess energy that causes heart excitement or heat caused by lung infection can cause the tip of the tongue to turn red.

3. Pale tongue: physical weakness

A tongue that is too white indicates a lack of blood, which means there is a tendency towards anemia, and is also accompanied by symptoms such as easy fatigue, dizziness when standing, and palpitations. In addition, when the body temperature is too low, such as when it is cold, it can also cause poor blood circulation and make the tongue turn white, so be careful to distinguish.

4. Tongue tremor

Japanese medical experts found in a survey that more than 70% of people do not realize the vibration in the early stages, and by the time they discover it, it is often too late. It is recommended that you adjust your work and rest schedule as soon as possible, do not stay up late, and eat a healthy diet, otherwise you will soon face the risk of neurasthenia!

5. Thick tongue coating

The tongue coating on the tongue can be easily scraped off like tofu dregs, which may be due to gastrointestinal dysfunction or overeating. If you have this kind of tongue coating all the time, it is best to go to the gastroenterology department and let the doctor help you reduce stomach fire.

6. Thin tongue coating

The tongue coating falls off for no reason and the surface of the tongue becomes uneven in color. This is medically called "geographic tongue".

Korean medical experts pointed out that people with allergies are most likely to experience this condition, especially in spring and autumn. The appearance of "geographic tongue" indicates that your resistance is declining. It is recommended that you stay away from allergens such as pollen, seafood, small insects, etc. during this period to avoid being "infected".
