Fingernails are made by living skin cells in your fingers. So a skin condition such as
may lead to fingernail ridges. can also cause these ridges. If your body is low in protein, or vitamin A, a deficiency can sometimes be revealed by ridges in your fingernails. Vertical ridges are furrows that run from the tip of your fingernail down to the cuticle. They are sometimes called longitudinal striations or bands. Slight vertical ridges in fingernails often develop in older adults, possibly due to a slowing of cell turnover. This is when new skin cells produced below the surface of your skin rise up to take the place of dead cells that are discarded from the surface.
If you experience other symptoms like color or texture changes in your nails, it may be caused by a medical condition. In trachyonychia, or 20-nail dystrophy, the ridges may be accompanied by a change in color to your nails, or your nails may become rough or brittle. can also trigger vertical ridges and changes to your nails that make them concave, or spoon-shaped. Deep horizontal ridges, called Beauвs lines, are often symptoms of a serious condition. They may actually stop nail growth until the underlying condition is treated. Acute kidney disease may also be present if Beauвs lines appear. In addition, when Beauвs lines develop on all 20 nails, it could be a symptom of: Chemotherapy may also cause Beauвs lines.
Trauma to your nails can cause red or brown spots to form underneath your nails. However, if you notice dark brown, black, or red color changes under your nails and you havenвt experienced nail trauma, this can be a symptom of a more serious condition, such as or. Beau\’s lines are horizontal or transverse depressions in the nail (they can be seen in the fingernails, thumbs, toenails, or all nails) that may be confused with nail ridging. This phenomenon was originally described in 1846 by the French physician Joseph Honor Simon Beau. These lines are caused by diseases that affect the entire body, including malnutrition, ( ), diseases, severe infections (such as, and others), and metabolic disturbances, including poorly controlled.
However, Beau\’s lines can result from any disease process or illness that is severe enough to affect the growth plate of the nail. Malnutrition and for can also cause Beau\’s lines. or injury may also be a cause of Beau\’s lines or nail ridges. The timing of the disease can be estimated by measuring the distance from the Beau\’s line to the nail bed. Brady, Mark P. \”Fingernail and Toenail Abnormalities: Nail the Diagnosis. \” Feb. 1, 2017.
