Your nails can reveal important clues about your health. Changes in shape, color, or texture may indicate underlying conditions. For example, Beau’s lines—grooves across the nails—can signal a halt in nail growth due to severe illness, such as COVID-19 or chemotherapy.

Clubbing, where nails curve downward, may point to heart disease, while spoon-shaped nails are often linked to iron-deficiency anemia. Pitting or dents in nails may indicate skin disorders like psoriasis or eczema. Dark streaks running vertically along the nail can be a sign of melanoma, a serious form of skin cancer.

Terry’s nails, where the nail bed turns white, are associated with liver disease. Yellow nails may suggest fungal infections or more severe conditions like thyroid disease or lung disease. Regularly monitoring nail health can help detect and address potential health issues early.
