Broken nails can be a sign of a number of diseases, such as nutrient deficiencies, fungal infections, peri-nail eczema, etc., and cannot be said to be some kind of mysterious omen. It is recommended to believe in science and go to the hospital in time to receive relevant examinations. Nails can break easily due to poor nutritional intake, excessive dieting and weight loss, and other factors that lead to vitamin or trace element deficiencies in the body. For example, a lack of vitamin A will affect the normal keratinization of the skin and nails, which may make the nails more prone to breakage and breakage. Supplementation is recommended. In addition, fungal infections leading to onychomycosis may cause nails to become brittle, form cracks or thicken, or even break. Skin diseases such as periungual eczema in the skin near the nails may also cause poor nail growth and breakage. If the symptoms are obvious, go to a hospital dermatologist for treatment.
