The first thing we are going to do before entering to establish the meaning of the term pathogenesis is to determine its etymological origin. In this sense, we have to expose that it derives from Greek, since it is made up of three elements of that language:
-The noun "pathos", which can be translated as "disease".
-The name "genesis", which is synonymous with "origin" or "birth."
-The suffix "-ia", which is used to indicate "action".
In this way, based on this etymological origin, we find the fact that it means “study of the origin and development of a disease.
Pathogeny it is a branch of the pathology which is dedicated to analyze the origin of a morbid state . Its purpose is to study the events that are triggered from the action of an etiological factor and that reach the manifestation of the disease .
Also known as nosogeny , the pathogenesis investigates the emergence and development of conditions. Thanks to the pathogenesis, it is possible to know the etiology of discomfort (that is, its origin) and understand why symptom What the patient evidences. The pathogenesis is complemented by the pathophysiology , specifically oriented to the way the organism works when the disorder of Health .
What the pathogenesis does, in short, is to study the process that leads certain morbid factors to exert an influence on the body of a person, causing what we know as illness. To address the pathogenesis, it is possible to focus on the functional section (the pathophysiology ) or morphological issues (the pathology in its most general sense).
This also leads us, therefore, to refer to what is known as a pathogenic microorganism. This can be defined as one who has the capacity not only to enter the host (person, animal ...) but also to avoid or destroy its defenses. Not forgetting that later that will allow it to multiply and definitely take "possession" and settle in the aforementioned host.
It is important to note that each disease has its own pathogenesis. Psoriasis, the tuberculosis , diverticulosis and syphilis, to name just a few examples, are disorders that are triggered for different reasons, which can be studied according to their pathogenesis.
Thus, for example, we find that there is the pathogenesis of rabies, arthritis or Ebola, as well as other diseases. In the case, for example, of the pathogenesis of atrial fibrillation, we can say that it establishes that this progressive disease can occur mainly due to three types of causes:
-Risk factors, such as diabetes or hypertension.
- Cardiac causes, such as heart attacks or insufficiencies of various kinds.
-Non-cardiac causes, such as alcohol consumption, apnea or thyroid functioning problems.
The diseases that affect the animals and that are researched and treated by veterinarians also have their pathogenesis. In the case of veterinary , the notion has the same scope as in medicine, linked to the origin and development of the disorder.
