Nails are more than just a canvas for nail polish; It is a window into our overall health. Many people may not realize that the lines on their nails can provide important information about their health. These lines, whether vertical or horizontal, can indicate a variety of health conditions ranging from minor to severe. Understanding what these lines mean and when to seek medical advice is crucial to maintaining good health.

Types of lines on nails
Longitudinal (vertical) lines.
Longitudinal lines, also known as vertical edges, extend from the cuticle to the tip of the nail. They are relatively common and often increase with age.

Horizontal lines (BO).
Horizontal lines, or Beau’s lines, run across the nail from side to side. These lines are less common and can be more concerning because they often indicate underlying health issues.

Causes of longitudinal lines
aging
One of the most common causes of longitudinal lines is aging. As we age, the production of natural oils and moisture in the nails decreases, leading to the formation of these ridges.

Nutritional deficiency
A deficiency of vitamins and minerals, especially iron and zinc, can lead to vertical lines on the nails. Ensuring a balanced diet can help maintain healthy nails.

Medical conditions
Some medical conditions, such as rheumatoid arthritis and peripheral vascular disease, are associated with the formation of longitudinal lines on the nails.
