Choosing a Medical Specialty in Global Health: Your Ultimate Guide

Why Global Health Belongs in Your Specialty Decision

Choosing a medical specialty is hard enough. Adding a passion for global health can make the question “what specialty should I do?” feel even more complicated.

Do you need to do a global health residency track? Is international medicine only for certain specialties like infectious disease or family medicine? Can you realistically combine a demanding specialty with meaningful work abroad?

The answer: global health is less about one “right” specialty and more about aligning your skills, your values, and your lifestyle with the kinds of global problems you want to help solve.

This guide breaks down:

• How global health actually fits into different specialties
• How to choose specialty pathways that support sustainable international work
• Concrete questions and tools to use when choosing a medical specialty with global health in mind
• Practical training routes, timelines, and example career paths

Whether you are a pre-clinical student, on core rotations, or in the thick of residency applications and wondering how to choose specialty paths that keep your global health options open, this article is designed to be a roadmap.

Understanding Global Health as a Career Lens, Not a Single Path

Before you can decide which specialty fits best, it helps to clarify what “global health” really means for your career.

Global Health vs International Medicine vs “Medical Missions”

These terms are often used interchangeably, but they highlight different emphases:

• Global health

  • Focuses on health equity for all people worldwide, including marginalized groups within high‑income countries
  • Emphasizes systems, policy, social determinants, research, and capacity building
  • Includes clinical care but also public health, advocacy, program design, and implementation science

• International medicine

  • Typically refers to providing clinical care across borders (e.g., working in a hospital in Malawi, a refugee camp in Jordan, or disaster settings)
  • Often short‑ or medium‑term clinical work abroad

• Short‑term “medical missions”

  • Brief trips, often from high‑income to low‑ and middle‑income countries (LMICs)
  • Increasingly critiqued if not well‑integrated with local systems or long‑term partnerships

For your specialty choice, the key question is less “Which specialty is the global health specialty?” and more:

How do I want to contribute to global health—primarily as a clinician, educator, researcher, advocate, program designer, or some blend?

Your answer will shape which specialties and training paths make the most sense.

Step 1: Clarify Your Global Health Goals Before Choosing a Specialty

Before deciding how to choose specialty programs or ranking your residency list, you should identify what you actually want your global health career to look like.

Reflect on These Core Questions

1. What kinds of problems do I want to work on?

   • Infectious diseases (HIV, TB, malaria, emerging infections)
   • Maternal and child health, obstetrics, and reproductive rights
   • Noncommunicable diseases (cardiovascular disease, diabetes, cancer, mental health)
   • Surgical and anesthesia access (global surgery)
   • Emergency response and disaster medicine
   • Health systems strengthening, policy, and financing
   • Refugee and migrant health

2. Where do I imagine myself working most of the time?

   • Primarily in the US (or your home country) with periodic work abroad
   • Living long‑term in a specific country or region
   • Working from a global institution (NGO, WHO, academic center) with regular field travel

3. How clinical do I want my career to be?

   • 80–100% direct patient care
   • A mix of clinical work and research/program work
   • Primarily research, policy, or program leadership with limited clinical practice

4. What kind of daily work energizes me?

   • Longitudinal relationships and primary care
   • Procedures and operative work
   • Acute, high‑intensity environments (ED/ICU)
   • Detailed diagnostic thinking and subspecialty focus
   • Teaching and capacity building
   • Data, research, systems, and strategy

Your answers will help you filter options when choosing medical specialty paths that genuinely fit who you are and how you want to practice global health.

Aligning Personality and Values with Global Health Roles

Some broad tendencies:

• Big‑picture thinkers who like advocacy, writing, policy, and working across disciplines may gravitate toward:

  • Internal medicine, pediatrics, family medicine, psychiatry, OB/GYN, preventive medicine, or combined programs
  • Plus MPH/PhD or global health policy work

• Hands‑on proceduralists who enjoy technical skills and immediate impact might be drawn to:

  • General surgery, OB/GYN, anesthesia, EM, orthopedics, ophthalmology
  • Roles in global surgery, trauma, safe obstetric and anesthesia care

• Educator‑builders who like teaching and system design may find:

  • Generalist or broad specialties (IM, pediatrics, FM, EM, OB/GYN)
  • Academic global health partnerships and capacity building roles

There is no single right answer to “what specialty should I do for global health?” There are multiple viable routes, but not all will fit you equally well.

Step 2: How Different Specialties Fit into Global Health

Below is an overview of how major specialties intersect with global health, including strengths, limitations, and example career paths.

1. Family Medicine

Strengths for Global Health:

• Very broad scope: adult medicine, pediatrics, women’s health, basic procedures, sometimes obstetrics
• Highly useful in rural, resource‑limited, and primary care settings
• Commonly integrated into global health residency track options in the US
• Well aligned with health systems strengthening and community‑based interventions

Limitations:

• In some countries, “family medicine” is not officially recognized as a distinct specialty
• In tertiary urban hospitals abroad, your role may be more like a general practitioner

Example Global Health Roles:

• Longitudinal work with rural district hospitals or health centers
• Leading primary care training programs in LMICs
• Working with NGOs on chronic disease management, HIV, TB, or maternal-child health

2. Internal Medicine (and Subspecialties)

Strengths:

• Strong foundation in adult medicine and complex disease management
• Highly relevant to global burden of disease: HIV, TB, cardiovascular disease, diabetes, chronic lung disease
• Opens paths to subspecialties highly relevant to international medicine:
  • Infectious disease, cardiology, pulmonology/critical care, oncology
• Many large academic centers offer internal medicine global health residency track options or global health pathways

Limitations:

• Less pediatric or obstetric exposure (unless you pursue med‑peds or additional training)
• Some subspecialties may limit flexibility for work in resource‑limited, generalist settings (e.g., advanced electrophysiology)

Example Global Health Roles:

• Running HIV/TB programs and training local clinicians
• Noncommunicable disease policy work and research (hypertension, diabetes, heart failure)
• Academic global health centers combining patient care, implementation science, and system design

3. Pediatrics

Strengths:

• Maternal and child health is central to global health priorities
• High global burden from neonatal conditions, infections, nutrition, and vaccine‑preventable illnesses
• Common global health tracks within pediatric residencies
• Opportunities in refugee camp health, malnutrition programs, and child health systems

Limitations:

• Primarily focused on <18 age group, which may limit flexibility in some environments where you might be expected to see all ages unless you have additional training
• Some settings prioritize adult care due to burden of chronic NCDs

Example Global Health Roles:

• Designing and leading child health and immunization programs for NGOs or governments
• Academic careers in global neonatal care, vaccine implementation, or pediatric infectious disease
• Capacity building in pediatric hospital systems

4. OB/GYN

Strengths:

• Maternal mortality and reproductive health are core global health concerns
• High demand in many low‑resource settings for emergency obstetric and gynecologic care
• Natural fit with family planning, gender equity, and human rights work

Limitations:

• Coupling surgery, emergencies, and call can make flexible travel harder early in career
• Very procedure‑heavy; less emphasis on broad adult internal medicine

Example Global Health Roles:

• Working with ministries of health or NGOs on safe obstetric care programs
• Fistula repair or complex gynecologic surgery in regional centers
• Reproductive rights advocacy and policy work at national or global levels

5. General Surgery and Surgical Subspecialties

Strengths:

• Huge global unmet need for essential and emergency surgery
• Work in trauma, hernia repair, cesarean capabilities, orthopedics, and burn care is extremely impactful
• Growing field of global surgery with active academic and policy communities

Limitations:

• Subspecialties with very high‑tech needs may be less applicable in basic or district hospitals
• Operative schedules and call may complicate long stints abroad unless you design your job for it

Example Global Health Roles:

• Developing district hospital surgical capacity and training nurse‑anesthetists or non‑physician clinicians
• Academic global surgery research on access, outcomes, and cost‑effectiveness
• Policy work on national surgical, obstetric, and anesthesia plans (NSOAPs)

6. Emergency Medicine

Strengths:

• Acute care skills are transferable across settings, including low‑resource environments
• Disaster response, humanitarian emergencies, and conflict zones often rely heavily on EM clinicians
• Flexible schedule can facilitate periodic international deployments

Limitations:

• EM as a distinct specialty doesn’t exist in all countries; role may be less well‑defined
• Work in some regions may default to general practice without clear EM infrastructure

Example Global Health Roles:

• Humanitarian work with NGOs (MSF, ICRC, etc.)
• Building emergency care systems and triage protocols in LMIC hospitals
• Pre‑hospital care and injury prevention policy work

7. Psychiatry

Strengths:

• Enormous global burden of mental health conditions and very limited workforce
• Opportunity to integrate task‑shifting, community health workers, and culturally sensitive models
• Growing research and implementation science in global mental health

Limitations:

• Stigma and cultural differences around mental health may affect roles and acceptance
• In some settings, psychopharmacology options may be limited

Example Global Health Roles:

• Designing and evaluating mental health integration in primary care
• Collaborating with NGOs on trauma‑informed care for conflict‑affected populations
• Academic careers in global mental health research and curriculum development

8. Anesthesiology

Strengths:

• Critical for safe surgery, maternal care, and trauma treatment
• In many LMICs, major shortages of trained anesthesiologists
• Skills in airway management, critical care, and perioperative medicine are highly portable

Limitations:

• Technology and medication availability may be constrained in many settings
• You may shift toward training and system design rather than direct high‑tech practice

Example Global Health Roles:

• Training and supporting non‑physician anesthesia providers
• Working with global surgery teams to improve perioperative safety
• Advocacy for anesthesia access and monitoring equipment

9. Combined and Less Obvious Paths

Several additional paths integrate well with global health:

• Med‑Peds: Highly versatile for child and adult care, ideal for primary care and HIV, TB, or NCD programs.
• Preventive Medicine / Public Health: More policy and systems‑oriented; some programs offer combined IM/FM + Preventive Medicine.
• Pathology, Radiology, Dermatology, Ophthalmology:
  • Pathology: cancer diagnosis, lab systems strengthening
  • Radiology: teleradiology, ultrasound training, imaging protocols
  • Dermatology: neglected tropical diseases, HIV‑associated skin conditions
  • Ophthalmology: cataract surgery and blindness prevention

When choosing medical specialty options, don’t assume only “traditional” global health specialties count. Instead, ask how your skills can fill critical gaps in underserved systems.

Step 3: Understanding Global Health Residency Tracks and Training Pathways

Once you narrow down your specialty interests, the next step is to understand how a global health residency track can shape your training.

What Is a Global Health Residency Track?

These are structured programs within a residency that:

• Offer longitudinal seminars or curricula in global health
• Provide mentored global health or international rotations
• Often include scholarly projects, quality improvement, or research
• Sometimes link with degrees (e.g., MPH) or certificates in global health

Specialties most likely to offer global health tracks include:

• Internal Medicine and Med‑Peds
• Family Medicine
• Pediatrics
• OB/GYN
• Emergency Medicine
• Psychiatry (in fewer locations but growing)

Questions to Ask Programs About Global Health

When evaluating programs for residency applications, you aren’t just asking “What specialty should I do?” but also:

• Global Health Structure

  • Is there a formal track, pathway, or certificate?
  • How many residents participate each year?

• Mentorship and Faculty

  • Are there faculty with active global health projects and regular time abroad?
  • What partnerships exist (universities, mission hospitals, NGOs)?

• Clinical Rotations

  • Are away rotations supported financially or only in name?
  • Are there established, long‑term partnerships versus one‑off trips?

• Scholarly Expectations

  • Are you required or encouraged to do a global health research/QI project?
  • Are there opportunities for presentation and publication?

• Ethical and Equity Focus

  • Do they emphasize ethical guidelines, reciprocity, and capacity building rather than “medical tourism”?
  • Do they host visiting residents/fellows from partner sites (bidirectional exchange)?

When thinking about how to choose specialty programs, a robust global health track can substantially enrich your training, but it should not be your only criterion. A solid core residency experience still matters most.

Dual Degrees and Additional Training

Many global health‑oriented physicians pursue extra training:

• MPH (Master of Public Health) – Common and valuable for:

  • Epidemiology and biostatistics
  • Program evaluation and implementation science
  • Health policy and management

• Tropical Medicine/Diploma in Tropical Medicine (DTM&H) – Useful for:

  • Infectious disease and travel medicine
  • Work in tropical environments and parasite‑heavy settings

• PhD or DrPH – For those aiming at:

  • Academic global health research
  • Long‑term careers in universities, WHO, CDC, or large NGOs

You don’t need to do everything at once. Many physicians work clinically for a few years, then step into degrees or fellowships that align with their evolving interests.

Step 4: Practical Frameworks for Choosing a Specialty with Global Health in Mind

When you are asking “how to choose specialty” or “what specialty should I do,” you’re really balancing three domains:

1. Who You Are
2. How the Specialty Fits Global Health Needs
3. What Lifestyle and Structure You Want

1. Who You Are: Core Reflection Questions

• Which clinical rotations did you actually look forward to (not just enjoy in retrospect)?
• Do you prefer:
  • Continuity vs episodic care?
  • Depth in one area vs breadth across many?
  • Procedures vs cognitive problem‑solving?
• How do you handle uncertainty and long‑term ambiguity?
• How important is work‑life balance, location flexibility, and schedule control?

Global health work is often logistically complicated. If your baseline specialty leaves you exhausted and resentful, even the most meaningful international work will be hard to sustain.

2. Specialty Fit with Global Health Needs

Look at major global burden of disease categories: maternal health, newborn care, infectious disease, injuries, mental health, and noncommunicable diseases. Ask:

• Does this specialty give me skills clearly applicable to large global health problems?
• Can I adapt these skills in low‑resource and non‑ideal environments?
• Are there known examples or mentors who have built global health careers in this specialty?

If you cannot easily find role models in your specialty doing global health, that doesn’t disqualify it—but it means you might be more of a pioneer and will need to build your own path.

3. Lifestyle and Structure for Sustainable Global Health Work

Think long‑term:

• Do you envision short‑term trips, repeating annually?
• Multi‑month sabbaticals?
• Long‑term relocation?

Different specialties (and practice models) vary in:

• Schedule Flexibility – EM, hospitalist medicine, and some locums roles can be more flexible
• Geographic Portability – Generalist skills are often easier to plug into new systems
• Income Stability – Some specialties make it easier to scale hours up or down to accommodate global work

A good test: can you imagine a realistic weekly/monthly and yearly schedule 10 years from now that includes meaningful global health work alongside your primary job, family, and other commitments?

Step 5: Concrete Steps You Can Take Now

Regardless of your training stage, you can start aligning your path with global health.

Pre‑Clinical and Core Clerkship Years

• Seek out global health interest groups and faculty mentors
• Take electives in public health, epidemiology, or health policy
• Engage with local underserved communities: refugee clinics, migrant health, FQHCs
• Use rotations to notice your genuine specialty preferences: energy, curiosity, and fit

Clinical Years and Residency Application Phase

• As you narrow specialties, explicitly consider:
  • How much global health integration exists in that field
  • The presence of a global health track at programs you’re applying to
• Ask targeted questions on interview days about:
  • International partnerships
  • Funding and protected time for global health work
  • Mentorship structures

Early Residency

• Join or apply to the global health pathway, if offered
• Start one long‑term global health project rather than many disconnected short‑term experiences
• Attend global health conferences (e.g., CUGH, ASTMH, global surgery meetings)
• Build relationships with faculty and peers working where you’d like to engage

Post‑Residency and Beyond

• Consider fellowships in:
  • Infectious diseases, global health, maternal-fetal medicine, EM global health, global surgery, etc.
• Negotiate job structures that formally carve out time for global work (e.g., 0.8 FTE clinical + 0.2 FTE global health program role)
• Maintain humility, continuity, and mutual benefit in your partnerships; avoid extractive or one‑sided models

FAQs: Choosing a Medical Specialty in Global Health

1. Is there a “best” specialty for global health?

No single specialty is “best.” Family medicine, internal medicine, pediatrics, OB/GYN, EM, and surgery all have strong global health roles, but psychiatry, anesthesia, radiology, ophthalmology, and others are also needed. The best specialty is the one that matches your interests and strengths, provides skills relevant to major global health needs, and is sustainable for you long‑term.

---

2. Do I have to do a global health residency track to work in international medicine?

A global health residency track is helpful but not essential. You can build a global health career through:

• Elective rotations abroad
• Mentored research or QI projects
• Post‑residency fellowships
• MPH or other graduate training

That said, a structured track can provide mentorship, funding, and a community that accelerates your development and helps you avoid common ethical pitfalls.

---

3. Should I choose a broad specialty (like FM or IM) instead of a narrow subspecialty if I want to work abroad?

Broad specialties are often easier to deploy in low‑resource, generalist settings, which is why family medicine, internal medicine, pediatrics, and EM are very common in global health. However, subspecialists are also needed—especially in infectious disease, maternal-fetal medicine, surgery/anesthesia, oncology, and mental health. If you are deeply drawn to a subspecialty, you can still play a big role in global health, especially in training, research, and system design.

---

4. I care about global health but don’t see myself working abroad long‑term. Is that still “global health”?

Yes. Global health includes:

• Working on research, policy, or implementation from your home institution
• Caring for migrant, refugee, or marginalized populations domestically
• Building telehealth, training, or consultative roles that support colleagues abroad

You can have a meaningful global health career even if you travel only occasionally—or not at all—so long as your work advances health equity and partnerships across settings.

---

Choosing a medical specialty in the context of global health is less about finding a single correct answer and more about intentionally aligning your skills, values, and training with the needs of patients and health systems worldwide. If you keep both your authentic specialty interests and your long‑term global health goals in view, you can design a career that is both impactful and sustainable.
