A family doctor is a medical professional who provides comprehensive healthcare to individuals and families. They are trained to diagnose and treat a wide range of health issues, from minor illnesses to chronic conditions. Family doctors often serve as the first point of contact for patients and can refer them to specialists when necessary. In addition to treating illnesses, family doctors focus on preventive care, helping patients maintain their overall health through regular check-ups, vaccinations, and health education. They build long-term relationships with patients, which allows for personalized care and a better understanding of each patient's medical history and needs.
