The appearance of transverse faults in toenails is considered to be caused by malnutrition of toenails, trauma and onychomycosis.
1. Toenail malnutrition: if the patient long-term partial food, weight loss, etc., resulting in the body malnutrition, may also lead to nail growth malnutrition, resulting in the phenomenon of toenail transverse fault.
2. Trauma: if the patient’s toenail is hit or extruded, resulting in damage to the patient’s nail plate, so that the nail tissue blood supply is insufficient, it is easy to appear the toenail with transverse fault line, but often may be a single nail.
3. Onychomycosis: due to the ringworm bacteria invade the toenail, it will lead to the abnormal growth of the nail plate, which may make the patient’s toenail appear the phenomenon of transverse stripe fault, and accompanied by the manifestation of the toenail thickening, turbidity and brittle.
If the patient’s toenails appear transverse fault and do not improve for a long time, it is recommended to go to the hospital in time for examination and treatment according to the cause of the disease.
