Etiology puts into perspective the causes of the disease, while the pathology describes in detail how it progresses. In short, pathology unwinds the scenario of the disease and how it develops in the afflicted person. The wheezing sound that accompanies asthma is a sign that the air passages are so constricted that they can almost produce a whistling sound. This inflammation makes the bronchioles larger, and, in response, mucus forms as a defense mechanism constricting the airspace and making it harder for the afflicted person to breathe. In the case of asthma, “pathology” delves into how the bronchioles of the lungs become inflamed by the previously mentioned risk factors. For example, when discussing a disease, such as asthma, its risk factors, such as allergens, genetic predisposition for weak lungs, excessive mucus formation, and the tendency to hyperventilate falls under “etiology.” Bacterial infection of the lungs and allergic rhinitis are additional risk factors than can bring about asthma.Īfter the etiology has been thoroughly discussed, the study of the disease moves on to pathogenesis, or pathology in layman’s terms. It’s the initial answer to how the disease comes about. When discussing how a disease came about, “etiology” is discussed first before “pathology.” Organisms that may cause the disease, as well as significant risk factors, fall under etiology. You won’t have to fear about being criticized for the use of either or both terms if you know when to apply them.
Knowing one from the other, however, can make a scientific paper or case study more effective. It’s common to mistake one for the other because, as mentioned earlier, they are almost synonymous.
Doctors and scientists may also use these terms when referring to a particular disease. Whenever diseases are discussed, experts in the field of epidemiology, which is the study of diseases, commonly use these terms. Without this example, you’ll have a hard time differentiating between them because they’re very closely related and have only one major difference.īoth “etiology” and “pathology” are scientific terms used to describe diseases. The best way to tell them apart is by using a clear-cut example.
