Changes to watch for, but don’t overdo it
If you notice that the lunula is taking up more space than usual—to the point of occupying more than a third of the nail—it may warrant a little attention. Some see this as an indirect sign of hyperthyroidism, hypertension, or even cardiovascular stress. However, this phenomenon must affect several fingers and be long-lasting.
A lunula that seems to disappear completely? It could indicate chronic fatigue, a lack of iron, or vitamin B12. But again, be careful: it’s best not to jump to conclusions based on a single nail.
