Doctor reveals 7 hidden nail problems: What they can tell you

The next time you wash your hands or apply hand cream, perform a quick self-examination:

Changes in the appearance of your nails.
Possible cause of horizontal ridges.
Beau’s lines: Illness, injury, or nutrient deficiency.
Crooked fingertips, swollen fingers.
Clubbed fingers: Possible heart or lung disease.
Concave, spoon-shaped nails.
Iron deficiency or thyroid problems.
Dark vertical lines.
Subungual melanoma: Get checked immediately.
Yellow nails.
Fungal infection, lymphatic problems, or smoking.
Pale or white nails.
Anemia, liver disease, or malnutrition.
Cracked or flaky skin.
Aging, dehydration, or thyroid disease.
🛡️Summary: Your nails are silent messengers.
From slight discoloration to unexpected textures, your nails can reveal much more about your health than you think.

While many nail changes, especially in old age, are harmless, others can be the first signs of more serious conditions, such as anemia, heart disease, or even cancer.

So the next time you look at your hands, don’t just admire your manicure.

Take a closer look at them.

Because sometimes the first signs of a problem are not in the chest or stomach, but in the fingertips.

And recognizing it early can be crucial.
