A Doctor is a trained medical professional who diagnoses and treats illnesses, injuries, and other health conditions. They play a crucial role in maintaining public health and often work in hospitals, clinics, or private practices. Doctors can specialize in various fields, such as Pediatrics, Cardiology, or Surgery, each focusing on specific aspects of patient care. In addition to treating patients, doctors also engage in preventive care, educating individuals about healthy lifestyles and disease prevention. They often collaborate with other healthcare professionals, including Nurses and Pharmacists, to provide comprehensive care and improve patient outcomes.
