Pulmonary fibrosis (PF) and other lung diseases may be related to complications in patients with Type 2 diabetes, according to a German study.

The study, “Breathlessness and Restrictive Lung Disease: An Important Diabetes-Related Feature in Patients with Type 2 Diabetes,” was published in the journal Respiration.

Breathlessness is reported by 1 in 4 patients in outpatient treatment settings. Acute and chronic lung diseases are usually the main causes of breathlessness. In particular, pulmonary disorders such as chronic obstructive pulmonary disease (COPD) and restrictive lung diseases, which includes PF, may be relevant contributors to shortness of breath.

Since both PF and diabetes patients exhibit epithelial damagewith inflammation leading to fibrosis, or scarring, researchers have been discussing whether PF may be a diabetes-related complication.
