A general practitioner is similar to a family practitioner in that they treat patients of all ages with a variety of health concerns. These doctors treat everyday ailments, some acute and chronic diseases, and also provid health checkups, physicals, inoculations and preventative care.
General practitioners differ from family practitioners because they are not required to complete an additional residency in family medicine after completing their medical school residency. Like family practitioners, general practitioners will also provide referrals to patients who are in need of a specialist.

An otolaryngologist is more commonly referred to as an ENT, someone that can treat medical issues you may be having with you ears, nose, or throat. This is a physician who is specially trained to diagnose and treat conditions of the ear, nose, sinuses, larynx (voice box), mouth, throat, head, and neck. These doctors treat patients through both medical and surgical means. For instance, an otolaryngologist may treat an obstruction of the nasal passage, caused by malformation of the nose, through rhinoplasty.

An obstetrician & gynecologist, or OB/GYN, is a physician who cares for women throughout their pregnancies, straight through to the delivery of their baby (obstetrician). They also specialize in annual care, as well as the diagnosis and treatment of disorders of the female reproductive system (gynecologist). Many physicians specialize in both of these fields in order to provide complete overall health services to women at every stage of life.

A family practitioner is a doctor who specializes in caring for people of all ages, at all stages of life. Rather than focusing on the treatment of one disease or patient population, family practitioners are often the doctors that people see for their everyday ailments, like cold and flu or respiratory infections, and health screenings. When necessary, family practitioners will provide referrals for conditions that require the expertise of another specialist.
The doctors may also provide physicals, inoculations, prenatal care, treat chronic diseases, like diabetes and asthma, and provide advice on disease prevention.
