Ash fingernails are mainly caused by fungi infections, nail injuries, low immunity, poor hygiene practices and genetic factors. The analysis is as follows:
Fungal infections: the most common cause of ash fingernails is the proliferation of fungi after intrusion into decks or beds. Facts such as skin fungi and yeast are everywhere and are more likely to breed in hot and wet environments. In places such as public baths, swimming pools, where the foot skin is slightly broken, fungi may take the opportunity to break into fingernails and gradually damage the nail structure, rendering it colourful, thicker and deformed。
2. Articular trauma: the injury to the fingernails resulted in the destruction of its integrity and provided an entry point for the fungal invasion. For example, heavy objects were thrown to the nails, and over-cut nails resulted in damage to the nail beds. Once the fingernails are injured and local defensive mechanisms are weakened, fungi are easily planted in the injured areas, thus triggering ash fingernails。
3. Low immunity: when human immunity is reduced, the body's capacity to resist external diseases is weakened. For example, in populations suffering from chronic diseases such as diabetes, aids or chronic use of medicines such as immunosuppressants, sugar-coated hormones, the body immune system is not effective against fungi attacks and is vulnerable to ash fingernails。
Poor hygiene practices: lack of attention to personal hygiene, such as long absence of foot washing and stockings, can leave the feet in a damp and dirty environment and facilitate fungi growth and reproduction. In addition, sharing of items such as slippers, baskets, etc. With others may result in the infection of fungus carried by others with ash fingernails。
Genetic factors: some grey nail patients have family genetic tendencies. Certain genes may affect the structure and function of nails and make them more vulnerable to fungi. Although genetic factors lead to relatively few ash nails, there may be a number of cases in some families。
Ash fingernails are contagious, and in daily life, as much as possible, they are not shared with others, such as nail blades and slippers, keep their hands and feet clean and dry, actively treat basic diseases to improve immunity and prevent the occurrence of grey nails。
