Diet, stress, hormones: what your lifestyle reveals
Our nails also tell us about our lifestyle. A stable, well-defined lunula often reflects a good diet: regular intake of protein, iron, zinc, and B vitamins. Conversely, overly restrictive diets, repeated fasting, or unsupported veganism can result in the gradual disappearance of the lunula.
Chronic stress, for its part, slows nail growth and can affect the overall appearance of the lunula. The same is true during periods of hormonal upheaval: postpartum, menopause, heavy treatments such as chemotherapy... all situations where nails become more fragile, sometimes ridged, and the lunula less visible.
A good habit? Taking a moment to observe yourself every month, in daylight. This doesn't replace a health checkup, of course, but it can sometimes help identify subtle changes even before more obvious symptoms appear.
When to Seek Medical Advice Without Delay?
If the lunula suddenly changes color, disappears completely, or becomes unusually deformed—especially if accompanied by signs such as intense fatigue, brittle nails, a pale complexion, or difficulty breathing—it's best to speak to a professional. The doctor may suggest a simple blood test to assess the condition.
People suffering from endocrine disorders, heart problems, or diabetes also benefit from incorporating nail examination into their routine care.
Finally, in case of persistent doubt, dermatologists and podiatrists are perfectly trained to examine nails using a comprehensive, preventative, and non-alarmist approach.
In short, the lunula is no substitute for a blood test, but it can provide some clues. The key is to observe it over time, without becoming alarmed by the slightest change. And if it seems to be telling you something, take the time to listen... calmly.
