What are the causes of clubbed fingers?

Clubbed fingers can be a symptom occurring in several diseases and conditions, which may cause visible changes to the fingers or toes, affecting particularly the nails. More specifically, it appears due to the activation of certain components within the bloodstream, which often accompanies such medical problems. The main cause of clubbed fingers is lung-related conditions such as cystic or pulmonary fibrosis, lung cancer, asbestosis and bronchiectasis, but it is not limited to these. Other possible causes are liver diseases, inflammation of the intestines due to Crohn’s disease or other similar condition, heart defects, other forms of cancer such as Hodgkin’s lymphoma, and overactive thyroid gland as a result of Graves’ disease.

We wanted a resource where people who are looking for better help can find it, because one of the issues that I have found is that the diagnosis takes a little bit, some people don’t know if they are diagnosed or not. This is something that it is important enough, that is why I wanted to put the information together.
