Doctor
A doctor is a licensed healthcare professional responsible for diagnosing, treating, and preventing medical conditions. Doctors undergo years of formal education and clinical training, usually starting with a medical degree (MBBS or MD), followed by internships and specialization. They can be general practitioners or specialize in areas like dermatology, surgery, pediatrics, neurology, or psychiatry. Doctors play a critical role in public health by managing chronic diseases, treating acute conditions, and guiding patients toward healthy lifestyles. Many work in hospitals, clinics, research institutions, or private practice. In addition to clinical care, doctors may also engage in teaching, medical writing, or policymaking roles to influence healthcare delivery systems.
