A chronic condition is a health condition or disease that is persistent or otherwise long-lasting in its effects or a

disease that comes with time. The term chronic is often applied when the course of the disease lasts for more than

three months. Common chronic diseases include diabetes, functional gastrointestinal

disorder, eczema, arthritis, asthma, cancer, chronic obstructive pulmonary disease, Lyme disease, autoimmune

diseases, genetic disorders and some viral diseases such as hepatitis C and acquired immunodeficiency syndrome.

An illness which is lifelong because it ends in death is a terminal illness. It is possible and not unexpected for an

illness to change in definition from terminal to chronic. Diabetes and HIV for example were once terminal yet are

now considered chronic due to the availability of insulin for diabetics and daily drug treatment for individuals with

HIV which allow these individuals to live while managing symptoms. Chronic illnesses.

In medicine, chronic conditions are distinguished from those that are acute. An acute condition typically affects one

portion of the body and responds to treatment. A chronic condition, on the other hand, usually affects multiple areas

of the body, is not fully responsive to treatment, and persists for an extended period of time.

Chronic conditions may have periods of remission or relapse where the disease temporarily goes away, or

subsequently reappears. Periods of remission and relapse are commonly discussed when referring to substance

abuse disorders which some consider to fall under the category of chronic condition.
