5 diseases that nails can reveal

Possibly quite ignored, nails are an important part of our fingers and toes. Though nails' primary function is to protect the tips of fingers and toes from injury, they also play a role in enhancing tactile sensation, and facilitating fine motor skills like grasping and picking up small objects. On the other hand, they also can be a window to our overall health. Changes in the color, texture, or shape of your nails might be telling you important things about what’s going on inside your body. Here are 5 things your nails might be saying about your health

2/7

Pale or White Nails

If your nails look unusually pale or white instead of their usual pinkish color, it could mean your body is low on red blood cells. This condition is called anemia. Red blood cells carry oxygen to your tissues, so when there aren’t enough, your nails lose their healthy color.

What to watch for:
Nails look pale or white
You may also feel tired, weak, or dizzy

Possible causes:
Iron deficiency (most common cause of anemia)
Vitamin B12 or folate deficiency
Chronic diseases like liver disease or heart failure

3/7

Yellow Nails

Yellow nails are often caused by a fungal infection, especially if the nails become thick, brittle, or start to crumble. But sometimes yellow nails can be a sign of more serious health issues like lung disease, diabetes, or thyroid problems.

What to watch for:
Yellow or yellowish-green nails
Thickened or crumbly nails
Nails growing slowly or separating from the nail bed

Possible causes:
Fungal nail infection
Lung diseases such as chronic bronchitis
Diabetes or thyroid problems
Nail psoriasis

4/7

Spoon Nails

Spoon nails, also called koilonychia, look like little scoops or spoons. The nails curve upward instead of having a normal flat or slightly curved shape. This unusual shape can be a sign of iron deficiency anemia or other health problems.

What to watch for:
Nails that are thin and concave, like spoons
Nails that may crack or peel easily
Possible causes:

Iron deficiency anemia
Hemochromatosis (too much iron in the body)
Heart disease or hypothyroidism (underactive thyroid)

5/7

Clubbing

Clubbing means the tips of your fingers get bigger and the nails curve around the fingertips, making them look round and shiny. This change happens slowly and can be a sign of low oxygen levels in your blood.

What to watch for:
Enlarged fingertips
Nails that curve downward more than usual
Soft or spongy nail beds

Possible causes:
Chronic lung diseases like COPD or lung cancer
Heart diseases that reduce oxygen in the blood
Liver disease or inflammatory bowel disease

6/7

Vertical Ridges

Vertical ridges are lines that run from the base to the tip of the nail. Most people have some ridges, and they often become more noticeable with age. Usually, vertical ridges are harmless.

What to watch for:
Raised or indented lines running vertically on nails
Nails may feel rough or uneven

Possible causes:
Normal aging process
Nutrient deficiencies, especially vitamin B12 or magnesium
Skin conditions like eczema or psoriasis

7/7

When to see a doctor

While many nail changes are harmless or caused by minor problems, some can be signs of serious health issues. You should see a doctor if you notice:

Sudden or severe changes in nail color or shape
Nails that become painful, swollen, or infected
Nail changes that do not improve with home care
Other symptoms like fatigue, shortness of breath, or unexplained weight loss
