Chronic illnesses last over 6 months and include conditions like cancer, heart disease, and arthritis. They are caused by genetics, lifestyle, and environment. People with chronic illnesses have significant needs related to employment, finances, health, housing, and self-esteem. Meeting these needs can be challenging, especially if the illness limits one physically or psychologically or impacts their ability to work. Access to resources may also be affected by one's socioeconomic status, age, or disabilities.
