WARNING: Horizontal Lines On Your Nails, Don’t Miss The Signs

Horizontal lines (Beau’s lines) are deep grooved lines that run from side to side on the fingernail or the toenail. They may look like indentations or ridges in the nail plate.

Fingernail or toenail abnormalities can tell you a lot about your health. They’re often a sign of a fungal nail infection or injury, but can sometimes indicate a more serious underlying disease.


Beau’s lines are caused when the body stops producing nail cells for a period of time, anywhere from a day or longer.

When the body starts producing those cells again, the nails begin to grow. As the nail grows out, Beau’s lines will appear on the nail and techs will be able to see where the nail’s development was affected.

These lines are caused by diseases that affect the entire body, including malnutrition, heart attack, liver diseases, severe infections (such as mumps, measles, pneumonia, and others), and metabolic disturbances, including poorly controlled diabetes.

Malnutrition and chemotherapy drugs for cancer can also cause these horizontal lines. Trauma or injury may also be a cause of Beau’s.

Kidney disease, thyroid disease, diseases of skin, skin cancers, various surgeries can also cause the appearance of these lines.

It is always recommended to meet an expert doctor soon with the appearance of the horizontal lines or the Beau’s lines on nails. The doctor will look for the respective underlying health issues causing the Beau’s line with appropriate medical tests and diagnosis and go for the essential treatments to eradicate the health problem and the symptoms of the Beau’s lines on nails.
Make sure you are visiting the doctor in case you start experiencing the following symptoms:

  • Appearance of clubbed nails and distorted nails
  • A new or a widened dark streak on the nail
  • If you have blue nails.
  • In case there occur pale and horizontal ridges on the nails.
  • In case there are white lines below the nails or in case there are white nails.
