The nails have always been purple and black, and the cause cannot be found, why is it that the cause

If it doesn't hurt or itch, it's best to go to a regular hospital for another check-up, which is likely to be a hidden major disease.

Nails can directly reflect the problem of the body part, it is recommended to go to a professional hospital for a check-up, which will help to diagnose correctly**, so as not to delay the condition.

Most women are more beautiful, not only on the face makeup, but also to trim the nails, so the beauty of the nails is also important for women, and the hands are also a person's second face. But sometimes there will be black and purple nails, even if they are repaired, they can't cover up this situation, so women are very anxious, and they don't know what is going on with black and purple nails? Let's take a look at the following introduction.

The changes in the five organs of human beings will be reflected in the nails accordingly. Usually, as long as you pay attention to the subtle changes on your nails, you can ** a person's health. If you look at the health of your nails, the key is the color and shape of your nails.

Healthy nails should be smooth and clean, with no longitudinal and horizontal grooves on the nail surface, no interfering spots on the nails, symmetrical nails, no deviation, no depressions or upturned ends. As far as normal nails are concerned, although there are many types, there are not exactly the same nails.

1. Insufficient blood supply, fingernails will turn purple.

If the blood supply to the human body is insufficient, it will cause local hypoxia of the fingers, and the color of the fingernails will gradually deepen, turning purple and black, and basically all fingers will have such symptoms.

2. 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.

3. Fingernails will turn purple in cold weather.

If the weather is too cold, wearing less will cause blood vessels to constrict, and peripheral circulation will be poor, and the fingernails will turn purple at this time. This will disappear as soon as it is heated.

Fourth, if the relatives have problems with lead and dirty, their fingernails will turn purple.

Cardiovascular diseases can also cause the nails to turn high and purple, which needs to be diagnosed by a doctor.

The color on the nails can also reflect a person's health, so we must pay attention to the details of life and find out the abnormalities of our body in time, so that we can ** in time. In addition, I remind friends to pay attention to physical protection at the same time, but also pay attention to hand hygiene, and develop a good habit of washing hands before meals.

1. The most common ** is the most common ** of thumb nails, such as the thumb being bruised, pinched, etc., which will make the nail bed bleed, resulting in black and purple bruises, and gradually the bruises will dissipate and turn purple and light red.

If the nail bruise is purple due to trauma, it is recommended to use a hot towel to heat the nail at a temperature of about 40-50 degrees to avoid burning the hand.

2. In addition, when the thumb is compressed, the nail purple phenomenon will also occur, which mostly occurs in some people like to make a fist and sandwich the thumb between the remaining four fingers, resulting in obstruction of nail blood flow, and the change of nail color caused by slow blood flow.

Generally, this phenomenon is only short-lived, transient, let the thumb relax for a while, the nail color will return to normal, you can use your fingers to gently rub to speed up the flow of blood.

3In addition, people who love to wear nail polish may like purple nail polish, and apply nail polish to their thumbs to show purple nails, which is also a phenomenon, but some straight men don't understand it and think that nails are unhealthy.

4. What is relatively rare for Sun Liang is that the thumb pointed out that if the thick nails are purple and other nails are also purple one after another, it may be related to some diseases, such as severe heart and lung diseases, which lead to lack of oxygen and blood supply to the end of the nail due to lack of oxygen and blood supply to the patient's body, and the symptoms of color and color.

This phenomenon needs to be paid attention to, and it is necessary to immediately seek medical attention to diagnose **, take active measures ** disease, and wait for the original disease**, the nails will slowly return to normal pale pink.

9 White: Pale nail beds, indicating qi and blood deficiency. Those who are white and moist and lightly ill, white and withered and rough are seriously ill.

Panonycholyphlos is seen in anemia, malnutrition, cirrhosis, chronic colitis, nail bite, Raynaud's disease, pulselessness, etc. Some leukonychia can be seen in tuberculosis, nephritis, lymphosarcoma, cancer. Punctate leukonychia (one or more white spots or white spots, white flocculent spots of varying sizes on the deck), digestive disorders, malnutrition, zinc deficiency, syphilis, etc.

Red: The nail bed is red and red, indicating qi and blood fever syndrome, the disease is light and shallow in those who are red and moist, and the disease is severe and deep in those who are red and withered. Nail bed hemorrhage, also belongs to red nails, if the free edge of the nail appears to form a longitudinal linear hemorrhage, it can be seen in coagulation dysfunction, drug allergies, subacute endocarditis, etc.

Yellow: The nail bed is yellow in color, indicating damp heat fumigation. Yellow and distinct, indicating a mild illness and a short course of illness.

Dull yellow indicates severe illness with a long course of illness. Yellow nail can be seen in hepatobiliary diseases, hemolysis, hypothyroidism, chronic adrenal insufficiency, nephrotic syndrome, carotenemia, etc.

Cyan: The nail bed is blue, suggesting cold, bruising, pain, and convulsions. Seen in hypoxia or with the use of atipin or phenolphthalein. Long-term illness is green and withered, indicating that the liver qi is about to be extinguished and the prognosis is poor.

Black: The nail bed is blackened, and the main cold syndrome, blood stasis, and pain syndrome. The appearance of black nails and withering after a long illness indicates that the kidney qi is about to be extinguished, and its disease is dangerous.

The appearance of one or several thin and black longitudinal lines on the nail surface indicates endocrine disorders, which can be seen in menstrual disorders, dysmenorrhea, malignant tumors, radiation sickness, etc. After receiving radiotherapy and chemotherapy for cancer, a black mark can be formed on the nail for each course of treatment, and each course of treatment is recorded in a circle.

Blue: It means that the liver is subjected to evil and blood stasis is blocked. Modern studies have found that oral administration of chloroquine, atipin and hemochromatosis, Wilson's disease, nitrite poisoning, and hypoxia can lead to blue nails.

Brown nails: common in acanthosis nigricans, adrenal insufficiency, or oral administration of phenolphthalein, antimalarial, etc.

Red-white half-nails: reddistal brown of the nails, glass-white proximal to the nail plate, well-defined, common in cirrhosis azotemia.

5. Careful friends will find that when we are bored in warm weather, the color will be more ruddy, and the nail color will be relatively ruddy, but in winter, the climate is cold, there is too little clothing or the fingers have just been taken out of the cold water, and the nail cover will have insufficient heat **, and the blood vessels will constrict, resulting in insufficient blood supply to the finger cover, and the fingernails will be purple.

When the weather is cold, when going out or doing things, try to wear gloves to avoid freezing nails, and when the nail cover is purple, quickly soak it in warm water to make the nail blood unobstructed, and generally restore normal nail color in about 3-5 minutes.

6. In addition, if you do not pay attention to your diet and eat stale vegetables or other foods, it may cause enterogenic cyanosis, zhiwu bend and nitrite poisoning, which will cause tissue hypoxia caused by the oxidation of normal low hemohemoglobin or the loss of oxygen delivery ability of methemoglobin, resulting in purple-black or blue nails.

Timely medical treatment, if the patient's illness is mild, it is generally not necessary**. Severe cases should induce vomiting, gastric lavage, and catharsis. Detoxification** can be given intravenously or orally with 1% methylene blue solution, which is effective, and high-dose vitamin C and glucose supplementation are required.

7 The blood supply of our human body parts starts from the heart, the farther away from the heart, the more insufficient blood supply, and the nail cover is at the end of the finger of the human body, its own blood supply is relatively small, if the patient still has some kind of insufficient blood supply, it will easily cause the local ischemia and hypoxia of the fingers, causing the color of the fingers to slowly deepen, turn purple and black, this phenomenon is more common in the people with anemia and the fingernails of people with insufficient blood gas.

Seek medical attention as soon as possible to rule out the symptoms of insufficient blood supply, if necessary, you can choose anticoagulant drugs and antiplatelet drugs, so that the blood can flow smoothly, increase the blood**, reduce the onset of insufficient blood supply, usually eat more vegetables and fruits, and exercise appropriately, which can help accelerate blood circulation and avoid insufficient blood supply caused by emotional agitation and excessive fatigue.

8. If the patient has purple lips in addition to purple nails, then it means that the patient may have respiratory diseases or is in a state of hypoxia, which is called cyanosis and cyanosis in medicine. It is due to the increase of reduced hemoglobin in the blood in the superficial microvasculature, which makes the ** and mucous membranes appear blue-purple symptoms, which is a manifestation of hypoxia in the human body, and many other diseases can cause cyanosis, such as respiratory diseases, cardiovascular system diseases, blood system diseases, etc.

At this time, people who are traveling or climbing mountains on the plateau should stop their activities, rest, and need to undergo artificial respiration to replenish oxygen if necessary; If the patient has respiratory diseases, bioavailable oxygen solution should be used to bypass the respiratory tract and directly absorb supplemental oxygen through the mucous membrane, digestive tract, **, etc.

Many people find that the color of their toenails has turned purple and black, which may be caused by physiological reasons such as cold attack or nutritional deficiencies, but also due to physical diseases, such as traumatic toenails, heart or blood diseases, and rheumatism and immune diseases.

Under normal circumstances, the color of the toenail should be pale red, if the color has changed, it may be an abnormality in the body, and it must be paid enough attention. For example, some people's toenails will turn purple and black, which is obviously an anomaly and must be found in time**. So what's the deal with purple and black toenails?

1. Physiological causes of purple and black toenails.

1.Attack by the cold: When the weather is warm, the color of ** is also more ruddy, and the same is true for the color of the toenails.

However, if it is in winter when the weather is cold, if the shoes worn are too thin, or the feet have just been taken out of the cold water, the color of the toenails will change and turn purple and black, which is due to insufficient heat and constriction of blood vessels.

2.Nutrient deficiencies: Nutrient deficiencies are also one of the common causes of purple-black toenails.

If there is a habit of picky eating or picky eating, then it is easy to have insufficient nutritional intake in the diet, the most common is insufficient intake of trace elements and vitamins, in which case the toenails may turn purple and black.

2. Pathological causes of purple-black toenails.

1.Trauma: If the toenail is traumatized, such as being hit by a hard object or being squeezed by something else, it can easily lead to internal bleeding, and the blood will clot and turn purple and black.

In addition, if the toenail is accidentally scratched and not treated in time, the bruise will also accumulate, causing the nail to turn purple and black.

2.Heart disease or blood disease: Purple and black toenails may also be a sign of heart disease or blood disease, because the color of toenails is related to the blood of the body, if you suffer from heart disease or blood disease, it is likely that there will be insufficient blood, which will lead to changes in the color of toenails, and purple and black phenomenon.

3.Rheumatic immune diseases: If the toenails appear purple and black for a long time, it may be due to rheumatic immune diseases.

With this disease, as soon as the toes are exposed to cold water or feel cold, the color of the toenails will change to purple or black, but after a period of time, they will return to normal.

If your toenail is purple and black, there are two possibilities, one is accidentally bruised or something hits, the toe turns from purple to black, and the other is that the diabetic patient will also cause the toe to be purple and black, this kind of toe from purple to black, can not be underestimated, or go to the hospital for a check-up, listen to what the doctor said.
