Clubbed nails, also known as digital clubbing, is a nail condition in which the fingertips or toes develop a specific shape and appearance. It is characterized by the enlargement or bulging of the fingertips or the rounded shape of the nail bed.
Clubbed nails are often associated with a variety of underlying medical conditions, including but not limited to heart, lung, and liver diseases. It can also be caused by certain genetic disorders, infections, and chronic low oxygen levels in the blood.
The exact mechanism behind the development of clubbed nails is not fully understood. However, it is believed to be related to increased connective tissue and blood vessel growth in the fingertips or toes. This process may be triggered by chronic inflammation, decreased oxygenation levels, or altered blood flow.
Clinically, clubbed nails are assessed by measuring certain angles and determining the presence of other associated signs, such as curving of the nail or nail plate thickening. Consulting a healthcare professional is important if you suspect you may have clubbed nails, as it may be a sign of an underlying health condition that requires medical attention.« Back to Glossary Index
