Occasional nail splitting is normal. However, if your nails are persistently brittle, discolored, painful, or changing shape, it’s important to seek medical advice. Nail changes can sometimes indicate underlying health conditions that require attention.
The Bottom Line
Your nails can be a small but powerful indicator of overall health. While everyday habits often play a major role in splitting and breaking, ongoing problems may signal nutritional gaps, hormonal imbalances, or other medical concerns. Paying attention to these signs—and making simple lifestyle adjustments—can help restore strength and resilience to your nails.
