Yes, rheumatoid arthritis (RA) can affect the lungs. About 40% of people with RA experience symptoms outside their joints, including lung problems. Approximately 1 in 10 people with RA will develop lung-related complications.

The same inflammatory response that affects joints in RA can also cause inflammation and damage to lung tissue. This happens because RA is an autoimmune condition where the immune system attacks healthy tissue throughout the body, including the lungs. Common lung conditions that can develop with RA include:

• Interstitial lung disease (ILD) - causing scarring of lung tissue and breathing difficulties
• Pleural effusion - fluid buildup around the lungs
• Pulmonary nodules - small growths in the lungs
• Bronchiectasis - damage to the airways
• Pulmonary hypertension - high blood pressure in lung arteries

Common symptoms of RA-related lung problems include:
• Shortness of breath
• Dry, persistent cough
• Fatigue and weakness
• Chest pain
• Difficulty breathing
