What Do Dents in Fingernails Mean?

Many of us do not take nail health issues, such as ridges, discolored nails, and changes in the shape of the nails. But these can be early indications of undiagnosed medical conditions like circulatory problems, iron deficiency, and thyroid diseases as well. Proper nail care is also essential. So, the next time you notice dents in your fingernails, do not ignore it. It is always better if you listen to what your nails are trying to tell you!

No Moons on Fingernails: What Does It Mean?

Fingernail moons are the rounded shadows at the base of your nails. A fingernail moon is also called a lunula, which is Latin for little moon. The place where each nail begins growing is known as the matrix. This is where the new cells are made that will make up the nail. The lunula is part of the matrix.

Not being able to see your fingernail moons doesn’t always mean that something is wrong with your health. Sometimes, you may only be able to see lunula on your thumbs, or possibly not on any fingers at all. In these cases, the lunula is most likely hidden under your skin.

Though the connection is not completely understood, an absent lunula can indicate anemia, malnutrition, and depression. Make an appointment with your doctor if you’re experiencing any of the following symptoms along with an absence of lunula:

  • lightheadedness or dizziness
  • unusual cravings, such as dirt or clay
  • fatigue
  • weakness
  • loss of interest in your favorite activities
  • significant weight gain or weight loss

Azure lunula

Azure lunula describes the phenomenon where the moons of the fingernails take on a blue discoloration. This may indicate Wilson’s disease, also known as hepatolenticular degeneration. Wilson’s disease is a rare inherited genetic disorder that causes an excess amount of copper to accumulate in the liver, brain, and other vital organs.

Symptoms other than azure lunula that occur in Wilson’s disease include:

  • fatigue
  • lack of appetite
  • abdominal pain
  • jaundice (yellowed skin)
  • golden-brown eye discoloration
  • fluid buildup in the legs
  • problems with speech
  • uncontrolled movements

Pyramidal lunula

Pyramidal lunula occurs when the moons of your fingernail form in a triangle shape. Most often, this is caused by an improper manicure or another kind of trauma to the fingernail. The moons may stay this way until the nail grows out and the tissue fully heals.

Red lunula

No Moons on Fingernails

Moons that are red in color, called red lunula, can indicate a number of different conditions which may significantly affect your health. Red lunula can appear in those with:

These conditions should be treated by a doctor, so contact your doctor if you develop lunula with red discoloration.

In most cases, having no moons on your fingers isn’t a sign of something serious. However, if you’re not seeing moons, or if you’re seeing changes to the shape or color of your moons along with other symptoms, you’ll want to visit your doctor. They’ll make sure you don’t have an underlying health condition that needs to be treated.

What do those white lines on your fingernails mean?

Chances are at some point in your life you've had white blob/lines on your fingernails, and wondered where the heck did these come from?


Well, we've got the answer for you. They're caused by minor trauma to the nail, meaning at some point during your fingernail's lifespan, you must have crushed the nail against your finger's skin. Your nail wasn't happy with the painful moment, and decided to retaliate by giving you a random white blob/line that stays until your nail grows out.

Other causes could be diabetes, which leads to problems with oxygenation of the fingertips, or *even worse* a fungal infection. 

MDHealth.com said it might be worth mentioning your nail beds to your doctor at your next visit, but there's no cause for alarm.

"However, other problems with your nails, in addition to white nail beds, might mean that you should get attention immediately. These include fingernails that are suddenly thickening, distorting in shape, or developing raised ridges. If there is any problem with your fingernails that changes their appearance, your doctor might want to run tests to figure out what the problem is."
