Nail clubbing can occur at any stage of life. It can develop in young individuals or older adults. Nail clubbing can be rapid or may take years before it becomes more apparent. This will depend on the cause and its severity. There are number of conditions that may cause clubbing of finger and nail. However, besides diseases, clubbing can occur just as a hereditary trait without any pathological cause. In some cases it is idiopathic. Diseases and disorders responsible for nail clubbing include mainly lung disease and heart disease.

How to Cure Clubbing:
Clubbing is sign of an underlying state of health. It can be related with a disease or just a hereditary trait. There is no specific treatment that can cure clubbing. The main aim is to find and treat the underlying cause, sometimes a life threatening cause such as lung cancer. Hence, clubbing often leads to exhaustive investigations to find the cause. Once the cause is treated, in many cases finger clubbing slowly recedes. For example if clubbing is caused as a result of congenital heart valve disease, surgical repair of valve can successfully treat its symptoms including clubbing. Lifestyle changes can also be effective. For example, a smoker must stop smoking. It will not only resolve nail clubbing but also reduce the risk of lung cancer and other ailments.
