Physicians in mens scrubs serve an important role in our society, and they have an effect on all of our lives. They diagnose and treat illnesses and injuries, examine patients, take their medical histories, and order and interpret diagnostic tests. They counsel their patients on hygiene, diet, and preventative healthcare. There are two kinds of doctors – medical doctors (doctors of allopathic medicine, or MD's) and doctors of osteopathic medicine (DO's). While both types use all accepted treatment methods, such as medications and surgery, DO's place particular emphasis on the body's musculoskeletal system using preventative medicine and holistic patient care. MD's work in one or more specialties such as anesthesia, internal medicine, family medicine, pediatrics, obstetrics and gynecology, surgery, and psychiatry.

Anesthesiologists in men's scrubs care for surgical patients and focus on pain relief. They are responsible for monitoring and maintaining patients' vital life functions – heart rate, blood pressure, breathing, and body temperature – during and after surgery. Internists provide diagnosis and nonsurgical treatment for patients with diseases and injuries of their internal organ systems – the stomach, digestive tract, liver, and kidneys. Like general or family practitioners, they are commonly looked upon as primary health care specialists. Family practitioners assessment and treatment many conditions, injuries, and ailments, and are usually the first point of contact for people who are in need of health care. Usually family practitioners have a base of regular, long-term patients, and they refer patients with serious conditions to specialists and healthcare facilities for intensive care. Pediatricians provide care to infants, children, and teenagers. They specialize in ailments which are specific to young patients, and they track patients' growth and development. Most of their work involves treating the common illnesses of childhood, giving immunizations, and treating minor injuries. Obstetricians and gynecologists specialize in women's health issues, particularly as this relates to the reproductive system and pregnancy. OB / GYNs counsel women through pregnancy, deliver babies and provide postpartum care. They also treat ailments such as breast and cervical cancer, and pelvic and hormonal disorders.

Surgeons specialize in treating injuries and diseases through operations. Surgeons in plus size scrubs correct physical deformities, repair tissues and bones after injuries, and perform surgeries on patients suffering from debilitating diseases. Most surgeons specialize in a particular body area or type of ailment. Psychiatrists are primary mental health caregivers who assess and treat mental illness using psychotherapy and medication. The formal educational and training requirements to become a physician are among the most demanding of any career, but the earnings are also among the highest. Many physicians work long and irregular hours; in 2002 a third of physicians worked over sixty hours a week. New physicians usually work as salaried employees in hospitals, clinics, group medical practices, or health networks rather than go into solo practice.
