Comorbidities are two or more diseases existing at the same time in the body. They are common for people with COPD because organ systems work differently when they do not receive enough oxygen. When a resulting condition occurs, it can be considered comorbidity.
The term âcomorbidityâ describes two or more disorders or illnesses occurring in the same person. They can occur at the same time or one after the other. Comorbidity also implies interactions between the illnesses that can worsen the course of both.
