People usually have a small, whitish, half-moon shape at the base of their fingernails, where the nail attaches to the cuticle. Many people cannot see a half-moon, or lunula, on their nails, while a missing half-moon may indicate a vitamin deficiency or a serious medical condition.
Nails grow from a pocket under the skin called the matrix. It helps make new cells. The cells then push out of the skin. Luna, the white half-moon shape on the nail’s root, stands for ‘little moon’, and can signify many different things. This part of the nail is white since the 5th basal Era layer is concealed under the blood cells.
Normally, the Lunula occupies one fifth of the nail and is most visible on the thumb. According to experts, the whiter the Lunula is, the healthier the individual will be. Lunula development may be affected by several factors including nutrition, physical condition, and environment.
When there is a problem with the above-mentioned aspects, the Lunula is likely to fade, shrink in size, and even disappear.
Furthermore, this part of the nail is highly sensitive and if something isn’t right with it, it is usually a sign of a health problem. Let’s look at what the reduction or complete absence of the Lunula may mean:
– When there is no Lunula on the thumb, this may be a sign of mental illness.
– The absence of the Lunula on the little finger can indicate problems with the intestines, pancreas, liver, or in women, issues with the reproductive system.
– If the Lunula or the index finger is smaller in size or completely gone, it may be an indication of intestinal problems.
– If the Lunula on your middle finger has shrunk, you might have a blood pressure problem.
– If there is no Lunula on the ring finger or if it is smaller, you might have thyroid gland problems.
Finally, whenever you notice changes in the Lunula of your nails, you should consult your physician to rule out any possible health complications.
