Your nails can reveal important health clues, with changes in shape, color, or texture indicating possible medical conditions. Dr. Sara Norris explains, “Nail health often reflects nutritional intake and digestion,” making them essential for health monitoring.

**Beau’s Lines: A Warning Sign**
Deep grooves across nails may indicate a temporary halt in growth due to illness or stress. “These lines can appear after COVID-19, chemotherapy, or high fevers,” says Dr. Bhavini Shah. If they persist, consult a doctor.

**Clubbing: Linked to Heart Health**
Downward-curving nails with swollen fingertips may signal heart disease. “Clubbing develops gradually,” notes Dr. Shah, often alongside fatigue and chest pain. A doctor’s evaluation is recommended if changes appear.

**Spoon-Shaped Nails: Iron Deficiency**
Nails curving inward can suggest anemia, often linked to poor nutrition or pregnancy. Symptoms include pale skin and fatigue. Dr. Shah advises seeing a GP for blood tests and iron supplements.

**Melanoma: A Hidden Danger**
Dark vertical streaks on nails may indicate melanoma, a serious skin cancer. “Early detection is key,” warns Dr. Shah. Any unexplained discoloration should be checked immediately.

**Yellow Nails: More Than a Cosmetic Issue**
Often caused by fungal infections, yellow nails can also signal thyroid disease or diabetes. Persistent yellowing should be examined by a doctor.

Monitoring nail changes can help detect health issues early, ensuring timely treatment.
