About Obstetricians And Gynecologists

Physicians diagnose and treat illnesses, injuries, and medical conditions across a wide range of specialties. General practitioners and family medicine physicians manage undifferentiated health problems and chronic conditions for patients of all ages, serving as the primary point of care and coordinating specialist referrals. Internists focus on adult medicine and often subspecialize in areas such as cardiology, gastroenterology, oncology, or pulmonology. Surgeons perform operative procedures to treat conditions ranging from appendicitis and cancer to orthopedic injuries and heart disease. Psychiatrists diagnose and treat mental health conditions using medication management and psychotherapy. Emergency physicians manage acute and life-threatening conditions in high-acuity settings. Pediatricians care for infants, children, and adolescents. Pathologists diagnose disease through laboratory analysis of tissue, blood, and other specimens. Radiologists interpret medical imaging studies. The educational pathway requires four years of medical school following a bachelor's degree, three to seven years of residency training, and often additional fellowship training in a subspecialty. Physicians are licensed by state medical boards and must maintain board certification through continuous medical education and periodic examinations.
