Clubbing
Understanding causes, symptoms, and comprehensive treatment approaches
What is Clubbing?
Clubbing refers to the enlargement of the fingertips or toes with characteristic changes in nail shape. It results from increased blood flow to the digital tissues, thought to be caused by chronic hypoxia (low oxygen) and the release of growth factors. Clubbing is not a disease itself but rather a sign of an underlying condition, most commonly lung or heart disease. The presence of clubbing should always prompt medical evaluation to identify the cause.
