Explaining Clubbing of Fingers and Toes in Pulmonary Fibrosis

Pulmonary fibrosis is a chronic lung disease where the tissue surrounding the air sacs in the lungs becomes scarred. This scarring, or fibrosis, makes it difficult for the body to get enough oxygen into the bloodstream. The common symptoms of pulmonary fibrosis include shortness of breath, persistent coughing, weight loss and loss of appetite, and chronic fatigue.

Did you know that pulmonary fibrosis can be difficult to diagnose and treat? 

If a person has had pulmonary fibrosis for a long time without receiving treatment, the lack of oxygen in the blood may also lead to clubbing of the fingers and toes (digital clubbing).

Although the exact reason for clubbing is unknown, we know it occurs when pools of fluid appear at the ends of the fingers and toes creating a rounding effect. It usually occurs in stages, with the fingernails lifting from the nail bed first and then they enlarge and start to round. Find out more about digital clubbing here.

    Thank you for this article. It has given me added education re IPF.
    I have also noticed an increased level of “pins and needles” in the fingers which can become numb, if I persevere using my hands. After a time it disappears. Is it also a side effect of IPF?

      Hi Ron
      I too have increased pins and needles in my fingers but they are numb most of the time now, it makes things awkward when trying to pick things up! Sometimes my numbness will wear off if I use my fingers for a while. I suspect that it is one of the side effects of IPF.

    I got finger clubbing as a result of radio active iodine treatment. The university in town requested to take films of my hands. The treatment was in 1978.
