Yellow Nails: More Than Looks
Yellow nails are often from fungus, but can also mean thyroid disease, diabetes, psoriasis, or lung disease.
Fungus makes the nail thick, crumble, or detach. It takes time to treat.
If your nails turn yellow without a clear reason like polish or fungus, see a doctor.
Early treatment of the real cause can stop issues and make nails normal.
Lasting yellowing means your body may be warning of an inside problem.
Act for Good Nail Health
Your nails give clues about your health. Not all changes are bad, but odd or lasting ones need a doctor.
Regularly looking at your nails can spot hidden health issues and help you act early.
