Health history is a record of a person's past and present health conditions, treatments, and medical events. It includes information about illnesses, surgeries, allergies, and medications. This information helps healthcare providers understand a patient's overall health and make informed decisions about their care. Additionally, health history often includes family medical history, which can reveal patterns of diseases that may run in families. By knowing about relatives' health issues, such as diabetes or heart disease, doctors can better assess risks and recommend preventive measures. Keeping an accurate health history is essential for effective medical care and maintaining overall well-being.
