What are the Causes of Nail Clubbing?

The causes of clubbing on finger and toenail can’t be pinned down to a single cause. Instead, there are several possible health conditions which may cause the tissues beneath your nails to thicken – leading to widened nails. Here are some of the health conditions which may cause clubbing.

  • Lung cancer – uncontrollable lung cell growth & generation
  • Asbestosis – lung-scarring caused by asbestos fiber inhalation
  • Cystic fibrosis – the genetic condition which causes excess mucus secretion due to improper water & salt transfer within the body
  • Bronchiectasis – widened and scarred airways caused by infections or mucus secretion failures
  • Pulmonary fibrosis – thickened and scarred lung tissue without any specific reasons



Since the clubbing on nails is one of the symptoms of an underlying health condition, the treatment will be targeted towards diagnosing the actual health condition and treating that. Some of the treatment options that you might get depending on your diagnosis include:

  • Chemotherapy and radiation therapy to tackle lung cancer.
  • Oxygen therapy, pulmonary rehabilitation & some other medicinal combination to reduce the symptoms of cystic fibrosis, pulmonary fibrosis, asbestosis, and bronchiectasis.

Your finger and toenails should return to their original state sometime after the health condition has been treated. Depending on the type of health condition you have, the treatment could take anywhere from a few weeks up to several years.

Some chronic conditions will require symptom management rather than treatments, so you can expect clubbing to take longer to resolve.
