The formation of excess fibrous connective tissue in an organ or tissue as a reparative response to injury or damage. This process can impair normal organ function when the scar tissue replaces healthy, functional tissue.
From Latin 'fibra' meaning 'fiber' and Greek suffix '-osis' meaning 'condition' or 'process.' The term describes the pathological process of excessive fiber formation in tissues.
Fibrosis is essentially your body's overzealous attempt to heal itself - like using too much duct tape to fix something delicate! In conditions like pulmonary fibrosis, the lungs become stiff and scarred, making it progressively harder to breathe as healthy, elastic lung tissue is replaced by rigid scar tissue.
