Rippled fingernails reveal secrets of possible disease (Page 3 ) | April 25, 2025

White Stripes
White, parallel horizontal lines that do not indent the nail surface may indicate liver or kidney issues. These lines, called Muehrcke’s lines, tend to fade temporarily when the nail is pressed and often appear on multiple nails simultaneously.

A decrease in blood protein levels, particularly albumin, can also cause these white stripes, commonly seen in those with malnutrition or chronic liver disease.

If Muehrcke’s lines are visible on multiple nails, consult with a medical professional as it may be a sign of protein deficiencies or kidney/liver problems.

‘Poor diet’
For most population, ripples are normal and can be fixed with some buffing or a healthy lifestyle change.

A balanced diet that’s rich in protein, vitamins and minerals – biotin, vitamin E, iron and zinc – can improve nail appearance over time.

Dr. Sara Norris, a naturopathic doctor based in Los Angeles, says to Healthline that “nail health is most often an indicator of poor nutritional intake or poor digestion.”

“Brittle, weak, and peeling nails are the most common concerns I see in my practice, and these symptoms are more often the result of a poor diet than of systemic disease,” she explains.

Your nails are offering you some valuable insights into your health, ranging from harmless signs of aging to potential indicators of underlying health conditions. Most causes are easy to treat but they’re a good indicator of poor health so pay attention to what they’re telling you!
