What condition of the nails requires medical attention?

Nail discoloration is a significant condition that may indicate underlying health issues, making it essential to seek medical attention. Changes in nail color can signal a variety of systemic health problems, such as fungal infections, nutritional deficiencies, or even more serious conditions like liver disease or melanoma. Discoloration could manifest as yellow, blue, or brown nails, each suggesting different potential ailments. Therefore, when discoloration is noted, it serves as a clear indication that a professional evaluation is necessary to determine the cause and appropriate course of action to protect nail health and overall well-being.

Healthy nails typically show no signs of distress or damage and do not require intervention. Ridged nails can sometimes be a normal variation, but often they are benign and can result from aging or minor health fluctuations. Severe hangnails, while sometimes painful and requiring care, do not usually indicate a systemic issue and can often be treated with proper hygiene and moisturizing techniques.
