Nail defects in diabetic patients
According to Shan, the former director of dermatology department of Guangzhou First People's Hospital, the key to judging whether a person's nails are healthy depends on whether his deck (nail surface), nail week and nail bed (fleshy part below deck) are defective and whether the color is abnormal. "Abnormal changes in nails are more common in middle-aged people, and there are many diseases that can be manifested from nails. The most common are diabetes, cardiovascular and cerebrovascular diseases and some hereditary skin diseases. "
Ms. Tang, 53, recently found that her nails are always easy to break. When she is doing housework, her nails will fall off one by one at the slightest touch. Moreover, she feels that her nails seem to be getting thicker and a little yellow. Ms. Tang went to the dermatology clinic. After examination, no fungal infection was found in Ms. Tang's nails. By asking about the medical history, it turned out that Ms. Tang's father had diabetes. Combined with some symptoms of Ms. Tang, the doctor suggested that Ms. Tang check her blood sugar. Results The results showed that Ms. Tang had diabetes.
Director Zeng Shan pointed out that patients like Ms. Tang have contact with each other from time to time in clinic. "The lesions in their nails are not primary, but problems with other systems and organs of the body, and then secondary nail lesions occur." In addition to diabetes, some patients with congenital heart disease, rheumatic heart disease, chronic heart failure and lung abscess, emphysema, silicosis, chronic fibrocavernous tuberculosis and chronic ulcerative colitis will have parrot-shaped nails, and their fingertips will swell like drumsticks, which are called "columnar fingers" in medicine.
"The abnormal changes of nails in patients with diabetes and heart disease are due to metabolic disorder in their bodies, which leads to vascular circulation disorder and blocked blood supply. As one of the extremities of limbs, nails often become brittle, defective, thickened or have symptoms such as finger swelling. " If these patients go to the dermatologist, the doctor will advise them to have a general examination after excluding primary onychomycosis. In addition, there is a hereditary skin disease called ichthyosis, and the patient's nails will also thicken and be easily damaged.
Anemic nails are like "teaspoons"
In addition to diabetes, cardiovascular and cerebrovascular diseases, the changes of nails can also reflect whether the human body is in a sub-health state. Healthy nails were originally pink, with an arc-shaped appearance and a natural luster.
According to experts from Guangzhou Hospital of Traditional Chinese Medicine, if you get iron deficiency anemia, the nutrition of all organs and tissues will be affected, and it will also bring nutritional disorders to nail tissues.

This spoon-shaped nail is not smooth, fragile and easy to break.

It is unscientific to distinguish health by looking at the "little sun"
Some people have small white spots on their nails. Some people say that this is a manifestation of poor gastrointestinal function, but experts believe that this is without scientific basis. According to reports, nails are vulnerable to injury because of long-term exposure, such as fingers getting stuck in the door, nails being squeezed and colliding. , leading to damage in the process of nail root stromal cells formation, white spots will appear, such as tearing off the barbs on the skin around the nails at will, which will also lead to white spots on the nails.

The so-called "little sun" refers to a small white semicircle at the bottom of the nail, which is called "meniscus" in medicine.
