What does it mean to have striped nails?

1. Vertical streaks: natural aging or a lack of nutrients?

Ridges that extend  from the base to the tip of the nail  are the most common.

What do they mean?

• With  age , these lines become more pronounced,  like wrinkles on the skin .

• They can also  indicate deficiencies  in  iron, magnesium or vitamin B12 .

When to worry?

If they  appear or become deeper , a  blood test  can help detect  a thyroid deficiency or disorder .

2. Horizontal streaks: a warning signal from the body

Unlike vertical ridges,  grooves that run across the nail from left to right  are more worrisome.  On Beau’s call lines , they often indicate  a temporary slowdown in nail growth due to illness or intense stress .

Possible causes:

• Serious trauma   or  infection .

• A  significant nutritional deficiency .

• Underlying diseases such as  diabetes, cardiovascular or respiratory disorders .
