Curled Toenails May Signal Underlying Health Concerns

Health Points

• Curled toenails can indicate circulatory or metabolic changes.
• Daily foot inspections help detect early nail alterations.
• Supportive shoes and balanced nutrition encourage healthy nail growth.

Curled toenails often develop slowly, and many adults dismiss the change as a natural part of aging. Paying attention to subtle shifts in nail shape can uncover important clues about overall wellness.

Podiatrists note that reduced blood flow, common after age forty, may cause the nail plate to thicken and curve inward. Regular movement and proper footwear help maintain circulation to the toes.

“Nails are like windows to what’s happening beneath the surface,” says Dr. Maria Lopez, a board-certified podiatrist with twenty years of clinical experience.

Nutrition also plays a role. Adequate protein, biotin, and iron support strong, flexible nails that resist curling. A simple blood test can reveal whether dietary adjustments are needed.

“We see the best outcomes when patients combine good shoes, routine foot checks, and balanced meals,” Dr. Lopez adds.

Trimming nails straight across and moisturizing the surrounding skin keeps edges from catching on socks or bedding. Avoiding tight shoes prevents pressure that can worsen curling.
