Kidney Disease: Muehrcke’s lines or half-and-half nails (a white portion near the cuticle and a darker area near the tip) might signal kidney issues.
Liver Problems: White nails with pink or red stripes can be a symptom of liver disease.
Cardiovascular Issues: Dark lines or splinter hemorrhages may indicate heart-related concerns.
5. Fungal Infections
Fungal infections can cause discoloration and thickening of the nails. Brown or yellow stripes are common signs of fungal nail infections.
6. Melanonychia
Dark, pigmented bands on the nails, known as melanonychia, can be benign but may also indicate melanoma, a form of skin cancer. If you notice dark stripes, especially if they are new or changing, consult a dermatologist promptly.
7. Medications
Certain medications, such as chemotherapy drugs, can cause changes in nail appearance. These effects are usually temporary and resolve once the treatment is completed.
