Onychomycosis softens and falls off

If the onychomycosis is more serious, the nails can be completely softened and fall off, so that new nails will gradually grow. There are many causes of onychomycosis. First of all, it is related to fungal infection. In addition, environmental factors, infectious factors, decreased autoimmunity, etc. are all important causes of onychomycosis. Understanding these causes will help better prevent and treat them. Let's take a look.

Onychomycosis softens and falls off

Onychomycosis is caused by fungal infection. After the diseased nail is removed, use iodine to remove the fungus until a new nail grows out. Now, with the advent of a variety of new drugs, oral medications for the treatment of onychomycosis have also achieved good results. Commonly used drugs include: Sporanox, Lamisil, Terbinafine, etc.

Causes of onychomycosis

1. Pathogens

The pathogens of onychomycosis can be roughly divided into three categories: dermatophytes, yeasts and fungi other than dermatophytes. Dermatophytes can be divided into: Trichophyton rubrum, Trichophyton mentagrophytes, and Epidermophyton floccosum; yeasts are mainly Candida parapsilosis and Candida albicans; molds can be divided into: Acremonium, Aspergillus, Canadian mold, Scopulariopsis brevis, Dark-colored Columnar Acremonium, and Colorless Columnar Acremonium. Onychomycosis is mainly caused by dermatophyte infection, among which Trichophyton rubrum infection is the most common.

2. Precipitating factors

(1) Environmental factors: The incidence of onychomycosis is related to the season to a certain extent, and the incidence rate is generally higher in warm and humid seasons. Ringworm is more likely to occur in the warm and rainy spring and summer, while the incidence is lower in the cold and dry autumn and winter. Onychomycosis is also closely related to the patient's living and working environment. If you live or work in a dark and humid environment for a long time, the incidence of onychomycosis will increase significantly. (2) Personal factors: For people who do not pay attention to personal hygiene for a long time, wearing non-breathable shoes or not changing socks frequently, etc., will provide a warm, humid and dark growth environment for fungi. In addition, if the nails are injured or impacted, the wound must be treated properly. Once fungi invade the gap, onychomycosis is not far away. (3) Disease factors: Onychomycosis infection is related to tinea pedis and tinea manuum. Many patients often suffer from tinea pedis first and then get onychomycosis. Onychomycosis is also related to the body's immune function. For example, when diabetes, AIDS, and long-term and excessive use of corticosteroids and immunosuppressants are used, the incidence of this disease is high and the condition is severe.

3. Predisposing factors

The incidence of onychomycosis is different between men and women, and the incidence rate is closely related to age. According to researchers' statistics, the incidence rate in men is higher than that in women, and the chance of onychomycosis in middle-aged and elderly people is higher than that in young people.
