Medical Definition of Exacerbation. Exacerbation: A worsening. In medicine, exacerbation may refer to an increase in the severity of a disease or its signs and symptoms. For example, an exacerbation of asthma might occur as a serious effect of air pollution, leading to shortness of breath.
An acute exacerbation is also called a COPD âflare-upâ or attack. One of the signs of a flare-up is that a personâs day-to-day COPD symptoms get much worse all of a sudden. Respiratory infections are a very common cause of COPD flare-ups.
