Chronic relapse occurs when a person has been treated for drug, alcohol or eating addiction but returns to the negative behavior. This is frustrating, sometimes painful, and can even be dangerous. Addiction is considered a chronic illness, therefore, relapse is common. Relapse can be treated and/or prevented with long-term, individualized therapy. This is a lengthy procedure that combines treatment, group support, support from family members, and treatment for other conditions. Chronic relapse also requires lifestyle changes, and avoiding situations that result in a return to negative behavior.
