A chronic condition is a human health condition or disorder 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. In medicine, the opposite of chronic is acute. A chronic study is further distinguished from a recurrent course; recurrent diseases relapse continuously, with periods of remission in between. Chronic conditions have often been used to describe the various health-related states of the human body such as syndromes, physical impairments, disabilities as well as diseases.
