Recent reports highlight the importance of subtle nail changes, especially lines and patterns, as indicators of underlying health issues in individuals over 40. Horizontal lines, known as Beau’s lines, may appear after severe illness, injury, or stress and can signal systemic conditions or nutritional deficiencies. Longitudinal lines or ridges running from nail base to tip, often linked to aging, may also indicate deficiencies in zinc, iron, or protein, or thyroid problems like hypothyroidism. Additionally, nail pitting or ridging can point to systemic diseases such as psoriasis or eczema.

These nail signs should prompt medical consultation if accompanied by changes in color, texture, or thickness, especially when persistent. While some lines are benign age-related changes, persistent or unusual patterns may suggest serious health conditions, making early diagnosis vital. Regular self-examinations and awareness of nail changes, combined with maintaining a nutrient-rich diet and good nail hygiene, can help detect health issues early and improve outcomes.

In conclusion, nail lines after 40 can reflect overall health and warrant attention. Recognizing these signs and seeking medical advice can lead to early intervention and better health management…
