Medical history is a term that describes a record of a patient's past health, including any conditions they have suffered from and any previous treatments they have received. Synonyms for medical history include health history, medical records, health records, and patient records. These terms are often used interchangeably, but can refer to different aspects of a patient's health history. A health history may include information about family medical history, lifestyle habits, and allergies, while medical records and patient records may focus on diagnostic test results, medications, and surgeries. Whatever term is used, a detailed record of a patient's medical history can help healthcare professionals make informed decisions about treatment and care.
