Even though clubbing is a widely recognized symptom of many diseases the physiological mechanism that actually causes clubbing is not well understood. Current understanding is that these diseases cause http://www.answers.com/topic/vasodilator in the distal circulation which leads to http://www.answers.com/topic/organ-hypertrophy of the tissue of the nailbeds and thus to the clubbed fingernails. Other factors that have been implicated are the local effects of growth factors (such as http://www.answers.com/topic/platelet-derived-growth-factor and http://www.answers.com/topic/hepatocyte-growth-factor) that are usually sequestrated in the pulmonary capillary bed. Many of the conditions associated with clubbing result in shunting across some of the capillary beds in the pulmonary circulation. http://www.answers.com/clubbing See the Related Links for "The aetiology of clubbing and hypertrophic osteoarthropathy." to the bottom for the answer.

Which people are most likely to exhibit clubbing?
The most common cause of clubbing is lung cancer. It is also commonly caused by other lung/heart diseases like interstitial lung disease or really any disease that causes chronic hypoxia. Hypoxia is a word used to describe the lack of sufficient oxygen supply in the body. Clubbing is caused by lack of oxygen in the blood, so on a basic note, any disease that causes the blood to be depraved of enough oxygen can cause hypoxia. The people most likely to exhibit clubbing are people with lung cancer, as lung cancer is responsible for over 50% of the cases.
