## What Causes Lines on Nails?
While specific lines have distinct medical implications, here are some broad categories of causes:
### Nutritional Deficiencies
* Lack of vitamins (A, B complex, C, D, E)
* Mineral deficiencies (iron, zinc, calcium)
These deficiencies can weaken nails, cause ridges, and affect nail color.
### Systemic Illnesses
* Diabetes
* Thyroid disorders
* Cardiovascular diseases
* Kidney or liver disease
* Autoimmune disorders
Many systemic diseases manifest signs in the nails before other symptoms become obvious.
### Physical Trauma
Repeated injury, nail biting, or pressure from footwear can cause ridges or hemorrhages.
