Alternate Names : Clubbing
Definition
Clubbing is a thickening of the flesh under the toenails and fingernails. The nail curves downward, similar to the shape of the round part of an upside-down spoon.
Overview & Considerations
Clubbing occurs with a wide number of diseases. It is most often found in heart and lung diseases that cause a lower-than-normal amount of oxygen in the blood. Clubbing may also be due to lung cancer, and diseases of the liver and gastrointestinal tract. Clubbing may also occur in families. In this case it may not be due to an underlying disease.
