Does ulcerative colitis affect the lungs?

Ulcerative colitis primarily affects the colon, but it can have systemic effects, including potential involvement of the lungs. Some patients may experience respiratory complications such as interstitial lung disease or pulmonary fibrosis, though these are considered rare. Additionally, certain medications used to treat ulcerative colitis can have pulmonary side effects. Overall, while the direct impact on lung health is not common, it is still possible for individuals with ulcerative colitis to experience respiratory issues.
