Comorbidity is the simultaneous presence of two or more medical conditions in a patient. It is a major public health issue that affects millions of people worldwide and can lead to poorer health outcomes and higher costs for health care services. By understanding the patterns and trends of comorbidity, health care providers can better predict and diagnose diseases, develop more effective treatments, and improve health outcomes for patients. Comorbidity is a key concept in medical research, health care planning, and preventive health initiatives.
