Jobs in Healthcare Series: What Is a Doctor?


If you’ve ever stepped foot in a medical office or hospital, then you’ve probably seen lots of different medical professionals – each with their own roles – all working together to deliver patient care. Upon closer observation, you may have noticed some name tags with abbreviations like MD, DO, or PA-C and wondered what they all meant.

Maybe you’re a pre-health student trying to figure out which path you want to pursue as a future career. Or, maybe you’re a curious patient who wants to know what the differences are between each of these positions for the next time you seek medical help. In any case, you’ve come to the right place! In this article, we’ll be discussing doctors – what they do, how to become one, and some of the pros and cons of the profession. Let’s dive into it! 😀

What Is a Doctor?

A doctor – also called a medical doctor or physician – is a healthcare professional with an M.D. or D.O. degree, who is licensed to legally practice medicine and treat patients. Doctors can be generalists, specialists, or subspecialists.

Generalists have a moderate amount of medical knowledge in a broad range of areas, which enables them to provide primary care and oversee chronic conditions. Contrastingly, specialists undergo extensive training in a particular area of medicine and treat patients with conditions that fall under that focus. Finally, subspecialists are doctors who choose to concentrate on an even more narrow area within a certain specialty and cultivate a very high level of expertise in that specific subspecialty.

Here are examples of generalist, specialist, and subspecialist physicians, as well as what types of patients and conditions they treat:

What Does a Doctor Do?

As physicians undergo extensive schooling and training, they have the largest scope of practice and greatest amount of responsibility out of all the jobs in healthcare. The role of a doctor is to use their medical knowledge and training to heal sick or injured patients, as well as provide patient education and advocacy.

Here’s a list of some of the roles and responsibilities of a doctor:

  • Conducting physical examinations
  • Ordering and interpreting labs, scans, and tests
  • Diagnosing and treating patients
  • Developing treatment plans
  • Prescribing medications
  • Performing medical procedures and surgeries
  • Providing health counseling and education

Unlike most other healthcare roles, physicians can practice independentlyOpens in a new tab. – meaning that they can diagnose and treat patients, perform procedures, and prescribe medications without supervision or collaboration. Physicians can make autonomous decisions in emergency situations, and all other medical staff must report to the attending physician.

To help ensure adherence to professional and ethical standards, physicians are bound by strict rules and regulations, as well as a code of ethics. While it isn’t a requirement, many physicians also choose to partake in other professional pursuits in addition to their clinical practice – including research, teaching, and working administrative roles.

What Are the Steps to Become a Doctor?

Education and Training

The path to becoming a doctor is by far the longest in the medical field. Earning an M.D. or D.O. degree is only half of the battle. A physician must successfully complete college, medical school, residency, and oftentimes a fellowship in order to practice. Overall, becoming a fully licensed, Board-Certified physician takes a minimum of ten years (including undergrad) and potentially more than 14 years.

To become a doctor (MD or DO), you must complete the following:

Degree or Certification EarnedDuration
Undergraduate programBachelor’s degree (B.S. or B.A.)4 years
Medical schoolDoctor of Medicine (M.D.) or Doctor of Osteopathic Medicine (D.O.) degree4 years (3 years for accelerated programs)
ResidencyN/A3-7 years
Fellowship (optional)N/A1-3 years

Tests and Exams

Alongside schooling and training, prospective doctors must pass several exams. The tests required to become a doctor are the MCATOpens in a new tab. and either the USMLEOpens in a new tab. or COMLEX-USAOpens in a new tab.. The MCAT is a standardized exam typically taken during undergrad by those who are planning on applying to medical school. Subsequently, the USMLE and COMLEX-USA are three-part exams taken throughout medical school and early residency that are required for medical licensure in the U.S. The USMLE is required for MD students, and the COMLEX-USA is required for DO students.

Becoming Board-Certified

Next is becoming Board-certifiedOpens in a new tab., which is optional but highly recommended. There are slightly more than a million physicians in the U.S.Opens in a new tab., and over 900,000 of them are Board-certifiedOpens in a new tab.. Board certification is a credential that indicates a physician has passed rigorous testing and demonstrated expertise in a particular specialty or subspecialty.

Applying for a State Medical License

The last step to become a practicing doctor is to apply for a state medical licenseOpens in a new tab., which enables a physician to legally practice medicine in a particular state. The physician must provide the required proof (verification of education, test scores, credentials, etc.), and an investigation for approval will follow. It’s important to note that each state has its own set of laws and statutes so a doctor looking to practice in multiple states will have to separately apply for each license.

What Are Some Important Things I Should Know About Becoming a Doctor?

Being a doctor has many benefits, including high impact, compensation, and prestige. It is currently rated #4 in Best Healthcare JobsOpens in a new tab. and #6 in Best Paying Jobs. The average MD and DO salaries are $201,918Opens in a new tab. and $163,908Opens in a new tab., respectively. (The average salary difference between MDs and DOs is mainly attributed to specialties, not degrees. MDs tend to specialize more than DOs, resulting in higher salaries.) In addition to a high salary, physicians enjoy good job security, since there will always be sick and injured people in need of care.

Physicians are highly respected, as being a good doctor requires good problem-solving, technical, and interpersonal skills. The doctor profession is highly altruistic by nature, since helping others is at the core of the work. Additionally, doctors have the largest scope of practice (can provide the largest range of medical services) out of all healthcare jobs. Most importantly, there’s no other profession that makes this level of direct, positive impact on others’ lives and wellbeing.

However, if you’re thinking of becoming a doctor just for the money, think again. There are significant downsides to being a doctor that should be taken into account, especially if this is a field you are seriously considering. Becoming a doctor is a huge commitment, and the biggest downside of being a doctor is the stress. Doctors are responsible for the lives and wellbeing of others so any loss or poor outcome can be demoralizing. Additionally, it can be frustrating when rules and policies – set by administration, the state, insurance companies, etc. – interfere with providing the best possible patient care.

The road to becoming a doctor is also long and difficult. Classes are rigorous, and all the time outside of class goes to studying, doing research, and making work connections. There is little time for your personal life so it’s not uncommon for personal relationships to suffer. Unless you’re getting help from family or have a scholarship, you’ll most likely graduate medical school with a significant amount of debt (on average more than $200,000Opens in a new tab.) due to loans. Once you enter residency, you’ll be working up to 80 hours per weekOpens in a new tab., including overnight shifts and shifts that last more than 24 hours. Although there are more resources now, sleep deprivation, anxiety, depression, and burnout still remain a reality of this profession.

Here’s a table outlining the main pros and cons of being a doctor:

As with any job, being a doctor comes with its benefits and drawbacks. Pursuing this path requires a lot of sacrifices and dedication so you need to be sure and truly love the work. Becoming a doctor is hard work, and while it isn’t for everyone, it can be a wonderful and highly rewarding career for the right person. 🙂
