Hundreds of millions of people of all ages worldwide live with two or more chronic conditions—commonly defined as multimorbidity. Those living with it are found to have poorer physical and mental health, higher risk of being admitted to hospital, and a higher risk of dying prematurely compared to people with only one chronic condition.
Given that the number of people living with multimorbidity is expected to rise in the future, finding better treatments is considered a major health priority. But despite multimorbidity being a leading cause of disability, research on treatments that target several conditions at once is still in its infancy. Few studies have investigated treatment options—and unfortunately, the results of these studies most often offer negligible improvements.
