| Etiology | The cause or origin of a disease or disorder. |
| Congenital | A condition or anomaly present at birth. |
| Acquired | A condition that develops after birth due to infection, injury, lifestyle, or environmental factors. |
| Iatrogenic | A disease or condition caused by medical treatment or intervention. |

| Pathogenesis | The sequence of events and mechanisms by which a disease develops and progresses. |
| Localized | Affecting a specific, limited area of the body. |
| Systemic | Affecting the entire body or multiple organs. |
| Acute | A disease with rapid onset and short duration. |
| Chronic | A disease that develops gradually and has a long duration. |
| Exacerbation | A worsening or flare-up of symptoms in a chronic disease. |
| Latent | A state of chronic disease in which no clinical signs are currently evident. |
| Complications | Additional health problems or adverse outcomes arising from a disease or its treatment. |
