The disease can become worse in its severity or show a higher number of signs, [[symptoms]] or new [[pathology|pathological]] changes, become widespread throughout the body or affect other organ systems. A medical treatment, such as [[medication|drugs]] or [[surgery]] may produce [[adverse effect (medicine)|adverse effects]] and/or produce new health problem(s) by itself. A new disease may also appear as a complication to a previous existing disease. 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, [[senescence|age]], health status, [[immune system]] condition, etc. complications may arise more easily. Complications affect adversely the [[prognosis]] of a disease. [[Non-invasive (medical)|Non-invasive]] and [[minimally invasive]] medical procedures usually favor less complications in comparison to [[invasive (medical)|invasive]] ones. ==Examples of complications== * Generalized [[septicemia]] (infection of the blood) may occur as a complication of an infected [[wound]] or [[abscess]] * Allergic [[Shock (medical)|shock]] can be a reaction to several kinds of [[anesthesia|anesthetic]]s, as a complication in a surgery * Fractured [[ribs]] and [[sternum]] may be a complication of [[cardiopulmonary resuscitation]] attempts in people suffering severe [[osteoporosis]] * [[Puerperal fever]] may be a common complication of [[childbirth]] and used to kill a large proportion of mothers before the advent of [[antisepsis]] and [[antibiotic]]s * [[Diabetes mellitus]] may present a series of complications in an advanced or more severe stage, such as [[gangrene]], [[diabetic foot]], [[blindness]], [[infection]]s, etc. * [[Thrombosis]] in the [[heart]] or [[brain]], causing [[stroke]] or [[acute myocardial infarction]] can be complications of [[blood coagulation]] disorders, [[phlebitis]] (inflammation of the [[veins]]), [[endocarditis]] and [[artificial heart valve]]s * [[Eczema vaccinatum]] is a rare and severe complication of [[smallpox]] [[vaccination]] in people with [[eczema]] * [[Hepatotoxic dementia]] is a possible complication of [[hepatitis]] and liver [[cirrhosis]] * [[Mental retardation]] is a common complication of untreated [[hydrocephalus]] * A [[paradoxical reaction]] to a drug that is the totally the opposite effect of the intended purpose of the drug.
