Inleiding tot de taal van de pathofysiologie I

Pathophysiology is the study of how diseases disrupt normal bodily functions and lead to clinical manifestations.

Several key terms are used to describe disease processes:

Etiology refers to the cause of a disease, such as an infection. Iatrogenic diseases result from medical interventions, for example, a urinary tract infection following catheterization.

Diseases may have an acute onset, with rapid and severe symptoms like those in appendicitis, or a chronic onset, progressing gradually over time, as seen in rheumatoid arthritis.

Some conditions are subclinical, involving cellular changes without noticeable symptoms; early kidney damage in diabetes is one such example.

Manifestations include signs observed by clinicians, such as fever, and symptoms reported by patients, such as pain.

A syndrome is a group of signs and symptoms that commonly present together and often affect multiple organ systems. For example, nephrotic syndrome is a kidney disorder marked by proteinuria, hypoalbuminemia, edema, and hyperlipidemia.
