The Half-Moon Shape On Your Nails Can be an Indicator of Many Diseases – Don’t Ignore It!

Before we start with this article, I would like to ask you a simple question – does the name lunula rings any bell? Have you noticed a crescent-shaped whitish area at the end of a fingernail? It isn’t just an area of pigment change under the nails – in fact, it is a highly sensitive area and you should make sure it doesn’t get damaged. The crescent-shaped whitish area of our fingernail, which the eye perceives as white crescent is very sensitive and extremely important part of the structure of the nail! This half-moon part is called the lunula (small moon in Latin) and it’s a very sensitive part of the nail. This part looks white, because is the fifth basal layer of the epidermis and it actually “hides” the blood vessels that are underneath. It’s most visible on the thumb but not everyone’s lunula is visible.


  1. If you do not have a lunula on your thumbs, it could be a sign that you suffer from mental illness or mental imbalance.
  2. The absence of the lunula or a very small lunula on the index finger can mean that a person has problems with the liver, pancreas, intestines or problems with the reproductive system.
  3. The absence of the lunula the middle finger may indicate problems with blood pressure.
  4. Lack of the lunula on the third finger can also mean a problem with the endocrine system.
  5. The absence of the lunula on the fourth or ring finger indicates bowel problems.
