Have you ever wondered what the differences are between an MD and a DO?  A PA and an NP? Whether you’re seeking primary care, specialized treatment, or simply curious about the people behind your health care, we’ve got you covered.

Understanding these unique roles empowers you to make informed decisions about your health care journey, ensuring you receive the best possible care tailored to your needs.

Meet the MDs (Medical Doctors):

Medical Doctors, commonly known as MDs, are often the first professionals that come to mind when we think of health care providers. These highly trained professionals have completed medical school, followed by residencies and fellowships in specialized fields. MDs can diagnose, treat and manage a wide range of health conditions.

Primary care physicians fall under this category, serving as the front line in your health care journey. They offer preventive care, routine check-ups and early detection of potential health issues. MDs in various specialties, such as cardiology, dermatology, and pediatrics, bring their expertise to address specific health concerns.

Understanding NPs (Nurse Practitioners):

Nurse Practitioners, or NPs, are an invaluable addition to the medical field. These highly skilled professionals have advanced nursing degrees and often hold specialized certifications. NPs work closely with MDs and have the authority to diagnose, treat and manage many health conditions independently.

With a focus on patient education and preventive care, NPs emphasize holistic approaches to wellness. They excel in building strong relationships with their patients, offering personalized care and guidance throughout your health care journey.

The World of DOs (Doctors of Osteopathic Medicine):

Doctors of Osteopathic Medicine, or DOs, are another essential part of the medical community. Like MDs, DOs complete medical school and undergo rigorous training in various specialties. However, their approach to patient care is distinctive.

DOs are trained in osteopathic medicine, which emphasizes the interconnection of the body’s systems and the importance of treating the whole person. They use osteopathic manipulative treatment (OMT) to diagnose and treat various conditions, aiming to restore balance and enhance the body’s natural healing abilities.

Embracing PAs (Physician Assistants)

Physician Assistants, or PAs, play a crucial role in supporting medical teams and enhancing patient care. PAs collaborate with MDs and other health care professionals to provide a wide range of services, from diagnosing and treating minor ailments to assisting in surgeries.

PAs bring a wealth of experience to the table, having completed rigorous education and training programs. Their versatility and ability to work across specialties make them a valuable asset in delivering comprehensive health care.

Medical Degrees Earned Outside of the US and Canada

You may notice that your primary care doctor has a degree other than an MD or a DO.  This usually means they earned the US-equivalent of the MD in another country.  For example:

  • MBBS (Bachelor of Medicine, Bachelor of Surgery): The MBBS degree is commonly awarded in many countries following a traditional medical education system. It is a primary medical degree that is equivalent to the MD in countries like the United Kingdom, India, Australia, New Zealand, and various other Commonwealth countries.
  • MBChB (Bachelor of Medicine and Bachelor of Surgery): The MBChB degree is the equivalent of the MD in countries like South Africa, Ghana, and some other African countries.
  • MBBCh (Bachelor of Medicine and Bachelor of Surgery): In Egypt and some other Middle Eastern countries, medical graduates are awarded the MBBCh degree, which is equivalent to the MD in the United States.
  • MDCM (Doctor of Medicine and Master of Surgery): In Canada, particularly in the province of Quebec, medical graduates are awarded the MDCM degree, which is equivalent to the MD degree awarded in the rest of Canada and the United States.

Exploring Beyond: Additional Medical Professionals

In addition to the aforementioned medical professionals, there is a plethora of other specialists contributing to your well-being. From certified nurse midwives (CNMs) delivering exceptional care during pregnancy and childbirth to clinical nurse specialists (CNSs) providing expertise in specific health areas, each role is carefully crafted to meet diverse patient needs.

Furthermore, the medical field continues to evolve, and new roles may emerge to address emerging health challenges and technologies.


Now that you have a better understanding of the diverse world of medical professionals, you are equipped to make informed decisions about your health care journey. Whether you seek primary care from an MD, holistic treatment from a DO, or personalized care from an NP, each professional plays a crucial role in your well-being.

Remember, open communication with your health care provider is key to achieving the best possible outcomes. By actively participating in your health care decisions and understanding the roles of these medical experts, you take charge of your well-being and embark on a journey to optimal health.
