Residency is a stage in medical training where doctors, known as residents, work in hospitals or clinics to gain hands-on experience in their chosen specialty. This period usually lasts from three to seven years, depending on the field, and allows residents to apply their knowledge while being supervised by experienced doctors. During residency, residents take on various responsibilities, including diagnosing patients, performing procedures, and participating in rounds. This training is crucial for developing the skills and confidence needed to become a fully qualified physician, ultimately preparing them for their future roles in healthcare.
