Step-by-step explanation:
Major medical disorders experienced by a patient during its lifetime are included in the problem list, which serves as an index to the patient's medical history. This list is crucial for providing healthcare professionals with quick access to important health information and is often used in conjunction with systems like the World Health Organization's (WHO) International Classification of Diseases (ICD).
