Pathophysiology uses specific terms to describe how diseases begin, progress, and impact the body.
Remission is a phase where signs and symptoms lessen or disappear.
A precipitating factor is a specific trigger that causes an acute episode. For instance, allergens can provoke asthma symptoms.
Exacerbation is a period when symptoms worsen, such as a flare-up of asthma with shortness of breath and wheezing.
A predisposing factor increases the likelihood of developing a disease. For example, long-term smoking raises the risk of atherosclerosis.
Complications are new health issues that arise during the course of a disease, such as heart failure following a myocardial infarction.
Sequelae are long-term effects that persist after the acute phase has ended, as seen in hemiplegia following a stroke.
Prognosis refers to the likely course and outcome of a disease, including chances of recovery. For instance, early-stage breast cancer typically has a favorable prognosis.
This lesson explores key terms that describe how diseases progress, their outcomes, and their distribution in populations.
