COMPLICATION, in medicine , is an unfavorable evolution or consequence of a disease , a health condition or a therapy . The disease can become worse in its severity or show a higher number of signs, symptoms or new pathological changes, become widespread throughout the body or affect other organ systems. A new disease may also appear as a complication to a previous existing disease. A medical treatment, such as drugs or surgery may produce adverse effects and/or produce new health problem(s) by itself. Therefore, a complication may be iatrogenic , i.e., literally brought forth by the physician.
Medical knowledge about a disease, procedure or treatment usually entails a list of the most common complications, so that they can be foreseen, prevented or recognized more easily and speedily.
Depending on the degree of vulnerability, susceptibility, age , health status, immune system condition, etc. complications may arise more easily. Complications affect adversely the prognosis of a disease. Non-invasive and minimally invasive medical procedures usually favor fewer complications in comparison to invasive ones.
Disorders that are concomitant but are not caused by the other disorder are comorbidities . This conceptual dividing line is sometimes blurred by the complexity of the causation or the lack of definite information about it. The terms sequela and complication are often synonymous , although complication connotes that the resultant condition complicates the management of the causative condition (makes it more complex and challenging).
