Symptom burden refers to the total number and severity of symptoms experienced by an individual with a particular medical condition or disease. It encompasses both physical symptoms (such as pain, fatigue, and nausea) and psychological symptoms (such as depression and anxiety). Research in this area focuses on understanding the impact of symptom burden on quality of life, functional abilities, and treatment outcomes for individuals with chronic illnesses or complex medical conditions. Studies may investigate the most common symptoms experienced by patients, the factors that contribute to symptom burden, and interventions to alleviate symptoms and improve overall well-being. Overall, the goal of research on symptom burden is to improve patient care and outcomes by effectively managing and addressing the diverse range of symptoms that can accompany various medical conditions.
