White spots at the base of the nails can have multiple causes. First, onychomycosis—commonly known as “gray nail”—should be considered; this condition is primarily caused by fungal infection. Second, leukonychia (white nails) may be responsible; this is typically associated with vitamin deficiencies in the patient and can be confirmed via blood tests. Other systemic diseases—including glomerulonephritis, chilblains, and leprosy—may also cause such spots, though these are relatively rare.
