Recovery refers to the restoration of a person?s health condition to normal. It is going back to the normal physiologic condition of a person before onset of the disease. Recovery from disease is usually dependent on a number of factors. A person?s immune status is the key. Individuals with a properly functioning immune system recover quicker. Any condition that suppresses the immune system such as diabetes adversely affects recovery. The nutritional status of a person directly influences their rate of recovery. A well nourished person stands a better chance of recovery. Proper treatment and adherence to medication accelerates recovery. A good social support system helps patients recover faster from illness. The age of a person also plays a role. Children and elderly tend to have a slower recovery process compared to the young adults and middle age group population. This is directly related to the functioning of the immune system, which is not optimum in the very young and the old.
