What about purple nails? Beware of abnormal nail color is a serious disease.

When fingernails are cold, careful friends will find that when the weather is warm, our skin color will be rosy and our nails will be relatively rosy. However, in winter, the climate is cold, we wear too few clothes or our fingers are just taken out of cold water, so the nails will be insufficiently heated and the blood vessels will contract, resulting in insufficient blood supply to the nails and purple nails.

It is suggested that when the weather is cold, if you go out or do things, try to wear gloves to avoid freezing your nails. When your nails turn purple, you should soak them in warm water to make the blood of your nails smooth. It usually takes about 3-5 minutes to restore the normal nail color.

It may be a poisoning phenomenon caused by intestinal cyanosis. In addition, if you don't pay attention to your diet and eat stale vegetables or other foods, it may cause cyanosis and nitrite poisoning. This disease will make normal low-iron hemoglobin oxidized or methemoglobin lose its oxygen supply ability, resulting in tissue hypoxia, resulting in purple-black or blue nails.

It is recommended to send a doctor for treatment in time. If the patient's condition is mild, treatment is generally not needed. Severe cases should induce vomiting, gastric lavage and catharsis. Detoxification can be treated by intravenous injection or oral 1% methylene blue solution, which has special effects. In addition, large doses of vitamin C and glucose should be given to supplement nutrition.

7 Insufficient blood supply The blood supply to all parts of our human body starts from the heart. The farther away from the heart, the less blood supply, while the fingernails are at the ends of fingers in all parts of the human body, and the blood supply is relatively small. If the patient still has some diseases with insufficient blood supply, it is easy to cause finger ischemia and hypoxia, so that the color of the finger gradually deepens and becomes purple-black. This phenomenon is more common in anemia population and insufficient blood gas population.

It is recommended to seek medical advice as soon as possible to eliminate the symptoms of insufficient blood supply. When necessary, anticoagulant drugs and antiplatelet drugs can be used to make blood flow unobstructed, increase blood supply and reduce the onset of blood supply deficiency. Eating more fruits and vegetables and exercising properly at ordinary times will help to accelerate blood circulation and avoid insufficient blood supply caused by emotional excitement and fatigue.

8 hypoxia If the patient's nails are purple and his lips are purple, it means that the patient may have respiratory diseases or be in a state of hypoxia. This phenomenon is medically called cyanosis and cyanosis. It is due to the increase of reduced hemoglobin in blood in superficial microvessels, and blue-purple symptoms appear in skin and mucosa, which is a manifestation of human hypoxia. Many other diseases can also cause cyanosis, such as respiratory diseases, cardiovascular diseases and blood system diseases.

It is suggested that people who are traveling on the plateau or climbing mountains stop their activities and rest, and need artificial respiration to supplement oxygen when necessary; If the patient suffers from respiratory diseases, a biologically effective oxygen solution should be used to bypass the respiratory tract and directly inhale oxygen through mucosa, digestive tract and skin.
