What Kind of Doctor Do I Need? Find a Specialist

Finding the Right Doctor for You

MedicineNet can help you find the right doctor for your condition.

Finding the right doctor can be a frustrating challenge. Our bodies’ systems are connected in complicated ways. Knowing which specialist is right for which ailment often requires time, research, and expertise. In the following slides, our experts will show you who treats what medical need, introducing many of the common—and surprising—types of doctors, including cardiologists, gynecologists, and bariatricians.

Do You Need a Specialist?

Your primary physician can refer you to see a specialist.

For many, the decision to bring in a medical specialist is determined by one’s health care plan. HMOs require patients to first see a primary care physician, who may then refer them to a specialist. On the other hand, PPO health plans require no referral, allowing patients to choose their own specialist.

Family Physician, Internist, or General Practitioner?

Learn the difference between the three types of general care physicians.

Most people first bring their medical concerns to a primary care physician. There are three main types of primary care physician:

Family Physician

Family physicians treat patients of any age and gender. They often specialize in treating children, women, or the elderly.

Internist

Internists typically treat adults, and are usually found in clinics and hospitals. They are trained in treating all of the body’s major organ systems.

General Practitioner

General practitioners often decide whether patients can be treated generally, or whether they need a specialist. General practitioners treat patients of all ages and genders.
