Healthy nails should be rosy, tough, smooth and shiny, and the crescent on the nail cover is clear and curved.
Judging from the color, healthy nails should be pink. If the nails turn pale or purple, it means that there may be some problems in the body.
Extended data:
Pale face may be blood deficiency. From the perspective of traditional Chinese medicine, while the nails are pale, the weakness of limbs is mostly blood deficiency. Doctors often judge whether blood deficiency is serious by the ruddy degree of patients' mouth, lips and conjunctiva.
If your nails are pale, there is a depression in the middle of the nail cover, and the edge of your nails is inclined and looks like a spoon, it is probably iron deficiency anemia. If the nails are pale and serious, even bloodless, accompanied by pain, it may be Raynaud's disease, and you need to seek medical attention in time.
Dr Tamara Leo, a dermatologist at the Cleveland Clinic in Florida, USA, reminded that nails are half white and half pink, so beware of kidney disease.
If you are blue or yellow, you should check your lungs. Dr Tamara Leo said that blue and yellow nails indicate that blood oxygen may be insufficient, and lung examination should be done to see if there are diseases such as water accumulation. However, yellow nails and skin may also be jaundice.
If the nails are yellow and the roots are red, you need to be careful of diabetes.
Deep purple may be poor blood circulation. Nails are dark and look dark purple. They are often stagnant, which often means poor blood circulation and may be a sign of cardiovascular and cerebrovascular diseases and lung diseases. It is recommended to go to the hospital for ECG and other examinations in time.
Black. Beware of melanoma. Black nails are mostly caused by congestion after trauma extrusion. If it is not caused by trauma, it is necessary to doubt the possibility of serious diseases such as melanoma. Dr Tamara Leo also believes that you should be alert to melanoma, especially when there are reddish-brown or black stripes under your nails.
