Why are there vertical lines forming on my fingernails?
Vertical lines on fingernails, also called ridges, can occur naturally with age or may be linked to certain health conditions like arthritis.
Explanation
Vertical lines on your fingernails are called ridges and can appear for different reasons. As people get older, these ridges can become more noticeable, which is a normal part of aging. However, sometimes these lines might be linked to health issues.
- Natural Aging: As you age, your nails may develop vertical ridges due to changes in the nail's growth.
- Health Conditions: Conditions like osteoarthritis and rheumatoid arthritis can also affect nails, including causing ridges.
If you notice other symptoms or changes in your nails, like color changes or pain, it might be a good idea to talk to a healthcare professional to rule out any underlying health issues.
