Beau’s lines

So-called “Beau’s lines” (named after the physician who first recognized the condition) — are deep grooved lines that run horizontally across the Nail Plate.

Though it isn’t known for certain what causes Beau’s lines, there are several diseases and disorders that have been shown to correlate with Beau’s lines, such as:

• Fungal infection in the nail fold (where the nail grows out of the fingertip)
• Calcium deficiency (Hypocalcaemia)
• General Malnutrition
• Diabetes
• Side-effect of chemotherapy

Certain physical activities may also cause Beau’s lines, such as deep sea diving.
