6 health problems that nail structure can reveal

Paying attention to nail structure and color, which can show many different health problems from diabetes to heart problems, is of great importance for the early diagnosis of serious health problems.

You don’t always have to go through complex tests to find out that something is wrong with your health. Sometimes just a glance at your skin tone, hair condition, and nails can reveal a lot about what’s going on inside your body.

Everything that appears on your nails, such as a white speck, a pink hue or ripple, has a different meaning and can give an idea about the condition of your lungs, heart and other organs.

Understanding these signs can help you detect serious ailments and take appropriate action in a timely manner.


Here are some of the health issues your nails can reveal.

No Half Moon

A healthy individual always has a half-moon shape at the base of the nail. This is part of the nail and reveals a lot about your health. In some cases, the missing half-month may be due to malnutrition, depression or anemia. If your nail starts to look red and you experience symptoms such as dizziness and anxiety, you should consult your doctor.

Pale or Yellow Nails

Healthy nails are smooth, without pits and slightly reddish. Any discoloration or paleness can be a sign of serious health problems. Pale nails reflect problems with your liver, kidneys or heart. Anemia can be a sign of liver problems, heart blockage, or malnutrition. A yellowish nail is linked to chronic bronchitis, thyroid disease, lung disease, diabetes or psoriasis.

Wavy Nails

Have you noticed any bulges or fluctuations in your nails? Vertical or horizontal lines tell a lot about your kidney and bone health. Wavy or pitted nail surfaces can be a sign of psoriasis or inflamed joints. Vertical lines accompanied by a change in nail color may also indicate anemia. Horizontal lines are more severe and may indicate an underlying condition such as kidney disease. The fluctuation in the nails is sometimes hereditary and becomes more pronounced with age.

Brittle Nails

A dry or brittle nail breaks quite often and easily. These types of nails may indicate underlying and untreated thyroid disease. Cracking or splitting nails with a yellowish tint can also be caused by a fungal infection. In some cases, nails can also become brittle due to overexposure to chemicals such as detergents, nail polish and nail polish remover.

White Dots

White spots on one or both nails can be a sign of zinc and calcium deficiency. It is not that harmful, but you need to increase your nutrient intake to avoid serious health problems in the future. White spots can also be caused by an allergic reaction, fungal infection, and injury to your nail.

Dark Lines

Black lines that appear under your nail can occur for a number of reasons. Sometimes they can occur just because of some trauma or injury from banging on the door or hurting your fingers. Another cause may be melanoma, a type of cancer. Therefore, if you see black lines on your nails for a long time, consult your doctor immediately.
