A family doctor is a medical professional who provides primary care to patients of all ages. They focus on overall health and wellness, diagnosing and treating a wide range of conditions. Family doctors build long-term relationships with their patients, allowing them to understand individual health histories and needs. In addition to treating illnesses, family doctors offer preventive care, such as vaccinations and health screenings. They also provide guidance on lifestyle choices, including diet and exercise, to help patients maintain good health. Family doctors often refer patients to specialists when more advanced care is needed.
