What causes finger clubbing?
-
The exact cause of finger clubbing is not known (idiopathic ), but it is a common symptom of respiratory disease, congenital heart disease, and gastrointestinal disorders.

⭕Respiratory disease causes of finger clubbing:
🔸Bronchiectasis (destruction and widening of the large airways)
🔸Cystic fibrosis (thick mucus in the lungs and respiratory tract)
🔸Lung abscess
🔸Lung cancer
🔸Pulmonary fibrosis (scarring of the lungs)

☡Notes:
It is worth noting that clubbing is not associated with chronic obstructive pulmonary disease (COPD). Indeed, the presence of clubbing in a patient with COPD should prompt a search for an underlying (lung) cancer. .

⭕Congenital cardiac disease causes of finger clubbing:
🔸Tetralogy of Fallot (combination of four structural defects).
🔸Transposition of the great vessels (rare condition in which the major vessels entering or leaving the heart are misconnected)
.
. ⭕Gastrointestinal disease causes of finger clubbing:
🔸Celiac disease (severe sensitivity to gluten from wheat and other grains that causes intestinal damage)
🔸Cirrhosis of the liver
🔸Inflammatory bowel disease (includes Crohn’s disease and ulcerative colitis)
🔸Liver cancer
.
.
⭕Finger clubbing can also have other causes including:
🔸Acromegaly (gigantism caused by a pituitary tumor).
🔸Atrial myxoma (tumor arising within heart)
🔸Dysentery (infectious inflammation of the colon, causing severe diarrhea).
🔸Endocarditis (inflammation of heart tissue, often infectious).
