Fingers turn purple for no reason? Why do fingernails turn purple?

When exposed to cold, the skin color of the fingers will gradually turn pale, then turn blue, feel painful, and finally turn bright red. Later generations called it the Raynaud's phenomenon.

Raynaud's phenomenon is mainly due to the constriction of blood vessels in the fingers. There are many causes of its disease, for example, scleroderma occurs in 80% to 90% of people.

Others, such as rheumatoid arthritis, nitrite poisoning, and lupus erythematosus, may also be possible. Therefore, patients should keep their hands and feet warm, do not smoke, and can use drugs that relax blood vessels.

Fingers turn purple I personally estimate 1It's cold and you're probably frozen to 2Hypoxia Hypoxia manifests itself first in the limbs of the person But I don't think you will be hypoxia Have you been feeling short of breath lately Tightness in your chest?

Basically, all I can think of are these two situations: Do you feel itchy in your purple area, and if so, you're sure you're frozen!!

It must be cold. That's what I'm like. When I feel cold, my hands turn purple. The lips are still purple. Ha ha. They all said I was poisoned.

I went to the hospital for a check-up, and my heart turned purple if I was not good.

Poor blood circulation. There is also the injury that compresses the blood vessels. Poor sleep affects blood circulation.

It's cold, first red, then flattened purple.

Purple nails may be caused by trauma, Raynaud's syndrome, cor pulmonale, etc., and need to be analyzed on a case-by-case basis.

1.Trauma: If a patient's nails have undergone trauma such as a blow or pinching bend, it can cause bruising of the patient's nails, which can lead to purple nails.

2.Raynaud's syndrome: The skin color of the fingers turns pale and then cyanotic during the attack, often starting at the fingertips and then spreading to the entire fingers, or even the palms of the hands.

Accompanied by localized coldness, numbness, pins and needles pain, or other abnormal sensations, 3Cor pulmonale: Patients with cor pulmonale disease may have symptoms such as dyspnea, chest pain, syncope, and cyanosis.

When patients have difficulty breathing, it can lead to a lack of oxygen and purple nails.

Probably cyanosis. That is, reduced hemoglobin (hemoglobin, a substance that carries oxygen in the purified blood, is dark red when it is not combined with oxygen, that is, reduced hemoglobin.

Too much. This substance is colored, and it will have color when it is exposed to the nails.

The cause of cyanosis may be hypoxia (this is the biggest cause.)

If this is the case, it has something to do with the lungs.

There may also be leakage of Zen that there may be too much hemoglobin in the blood.

In this case, people who are healthy will also have cyanosis.

It is more common in people living in alpine areas.

It's a healthy performance, and there's nothing wrong with that.

As long as there is no palpitation, palpitations, shortness of breath, etc., it should not be a heart problem.

If there is, it should be taken seriously.

It's best to get it checked.

It is also possible to cause poor blood flow in your hands.

If that's the case, be active and increase your circulation.

It may be a problem with the capillaries, which may be blocked for some reason (inflammation, foreign body, etc.), and the blood flow is not smooth, so there will be cyanosis. Digression, like those purple marks left between some lovers, may also be left by external forces. I just didn't pay attention to it at the time!

Anyway, it should be related to capillaries. When water is transfused, blood circulation is stimulated, so it may look better. In fact, as long as there are no obvious symptoms, it is fine!

In this case, you should pay attention to see if it is caused by poor local blood circulation, and you can use some blood-activating drugs to take a look.

It is mainly related to blood circulation, and is generally not a manifestation of disease, but may have a certain relationship with heredity. Don't worry, it's okay!

Alas, it's bad luck to get home....I'm the same, having a fever.

Cold hands and feet are related to the body's response to a drop in ambient temperature. Human beings are homeothermic animals, when the ambient temperature drops, in order to avoid the body temperature dropping, ** cryoreceptors will transmit information to the brain thermoregulation center, through the stimulation of the sympathetic nervous system, so that the body's muscle tone increases, causing trembling, increasing the production of heat energy in the body, and shivering when it is cold.

Trembling can increase the amount of body heat produced from 40 to 60 kcal per hour to 300 kcal, causing the blood vessels on the body surface to constrict, reducing the loss of heat energy in the body to keep warm.

In addition, when the weather is cold and the ground is freezing, most people stay at home, and the amount of sun exposure and exercise is reduced; In winter, platelets and coagulation are stronger in the blood than in summer; In addition, it is easy to cause respiratory infections in winter, increase blood viscosity and coagulation function, which will lead to poor blood circulation and aggravate the symptoms of cold hands and feet.

If the blood supply to the human body is insufficient, the fingers will be deprived of oxygen, and the color of the fingernails will gradually deepen, turning purple and black, and almost all fingers will have this symptom.

Anemia can cause purple fingernails.

People with low blood qi will cause their fingernails to turn purple, and most people with anemia will change the color of their fingernails.

If the weather is too cold, if you wear less clothes, it will cause blood vessels to constrict, peripheral circulation is not good, and at this time the fingernails will turn purple. This will disappear as soon as it is heated.

Probably cyanosis. That is, reduced hemoglobin (hemoglobin, a substance that carries oxygen in the blood, is dark red when it is not combined with oxygen, that is, reduced hemoglobin. Too much. This substance is colored, and it will have color when it is exposed to the nails.

The cause of cyanosis may be hypoxia (this is the biggest cause.) If this is the case, it has something to do with the lungs. It is also possible that there is too much hemoglobin in the blood.

In this case, people who are healthy will also have cyanosis. It is more common in people living in alpine areas. It's a healthy performance, and there's nothing wrong with that.
