What Specialty You Choose vs. What Your Body Looks Like After Residency

Welcome to the unspoken truth of medicine — where your specialty doesn’t just shape your schedule, salary, or social life. It shapes your spine, your skin, your cortisol levels, and sometimes your waistline

While most med students obsess over board scores, work-life balance, and passion when choosing a specialty, few pause to ask: “What is this going to do to my body?”

Let’s be honest — residency is physical warfare. You will age in dog years. But not all specialties wear you down the same way. From orthopedic surgeons with rotator cuff tears to pathologists with questionable vitamin D levels, your chosen field may slowly (or rapidly) remodel your body in ways no anatomy textbook warned you about.

So buckle up. This is your no-filter, anatomy-meets-reality tour of what your body might look like depending on the path you take.

1. Internal Medicine: The Slow Burn of Sedentary Suffering

Typical Body Changes:

Rounded shoulders and forward neck from hours hunched over EMRs.

Carpal tunnel flare-ups from chronic documentation and note-taking.

Puffy eyes from back-to-back call nights and pager-induced insomnia.

Central adiposity from vending machine dinners and interrupted workouts.

Despite their mental sharpness, internists often end up with tight hips, weak glutes, and subtly rising HbA1c levels by the end of residency. Their cognitive faculties may remain sharp, but their posture usually takes a hit.

Bonus: The development of a chronic “sitting face” — an expression shaped by caffeine-fueled contemplation and subtle existential fatigue — is not uncommon.

2. General Surgery: Battle Scars and Standing Fatigue

Typical Body Changes:

Varicose veins from hours of standing.

Foot deformities and chronic plantar fasciitis.

Neck stiffness from prolonged downward gazes in the OR.

Callused palms from retractors and endless scrubbing.

Surgeons exit training with muscular upper bodies but battered lumbar spines. Many can lift patients but struggle with flexibility. By PGY-5, walking may resemble post-marathon hobbling — and that’s just a Tuesday.

3. Pediatrics: Germ Exposure, Cute Chaos, and Knee Pain

Typical Body Changes:

Frequent URTIs from constant exposure to sick children.

Knee strain from frequent floor kneeling.

Lower back pain from bending over cribs and toddler-sized exam tables.

Dry hands and eczema from relentless sanitizing.

Pediatric residents may appear youthful due to their child-focused environments, but their joints, skin, and sinuses tell another story. Despite their cheerful demeanor, physical exhaustion sets in early — especially when carrying strollers and immune systems weakened by sleep debt.

Also: There’s a distinct likelihood of developing a gentle, sing-song voice inflection that doesn’t go away.

4. Emergency Medicine: Adrenaline Bodies with a Crash Price

Typical Body Changes:

Disrupted circadian rhythm due to rotating night shifts.

Jaw tension and TMJ issues from constant high-alert responses.

Shoulder tightness from lifting or restraining patients.

Gastrointestinal issues from erratic eating and excessive caffeine.

ED physicians often look physically fit — fast, focused, energetic. But they also live with chronic fatigue, adrenal dysregulation, and borderline dehydration. The “ED shuffle” — fast-paced, semi-chaotic movement between trauma bays — defines their gait and their daily life.

Sleep? Optional. Meals? Opportunistic.

5. Radiology: The Posture Plague

Typical Body Changes:

Cervical and lumbar strain from prolonged seated screen time.

Dry eyes and tension headaches from constant imaging review.

Increased stiffness from sedentary hours.

Variable weight outcomes based on snacking and movement habits.

Radiology residents may avoid sun exposure and chaos, but they often emerge with a hunched posture and the muscle tone of a librarian. Days blur into backlit hours of grayscale and silent rooms. They may know every structure in the body — but lose track of their own physical state.

6. Anesthesiology: The “Still but Stressed” Syndrome

Typical Body Changes:

Postural strain from rigid positioning during surgeries.

Eye fatigue from constant monitoring.

Muscle tension from high-stakes vigilance.

Hand strain from intubations and IV placements.

Anesthesia residents often maintain an outward calm, but the hidden stress of quietly managing emergencies wears them down. Their nervous systems are constantly engaged, despite physical stillness. It’s like meditating on a cliff edge — serene outside, adrenaline inside.

7. Psychiatry: Mentally Tuned, Physically Stiff

Typical Body Changes:

Neck and shoulder tightness from prolonged seated interviews.

Weight variability due to emotional strain and irregular routines.

Facial tension from constant empathic control.

Psychiatry residents carry emotional weight as if it’s a second stethoscope. Long hours of listening — to trauma, grief, and deep suffering — have psychosomatic consequences. Chronic fatigue, poor posture, and emotional depletion manifest quietly, often unnoticed even by the doctors themselves.

8. OB/GYN: A Mix of Surgery and Chaos

Typical Body Changes:

Sciatic discomfort and pelvic strain from prolonged deliveries.

Sleep disruption from erratic night calls.

Upper limb soreness from procedures and physical strain during births.

Chronic fatigue from the intense mix of surgical and emergent duties.

OB/GYNs live in a world of constant unpredictability — babies don’t care about your REM cycles. Between surgeries and births, they build significant core strength and resilience but often carry long-term musculoskeletal strain, menstrual irregularities, and emotional burnout.

Their white coats are usually hiding compression socks, snacks, and sheer determination.

9. Orthopedics: Built Like the Job

Typical Body Changes:

Well-developed upper body from repeated heavy lifting.

Joint strain, particularly wrists and shoulders.

Lower back problems from manipulating large bodies in awkward positions.

Knee strain from long hours standing in heavy lead gear.

Ortho residents start strong and stay strong — until they don’t. Their physical stamina is unparalleled during training, but the very nature of their job leads to orthopedic injuries. It’s not rare for a 40-year-old orthopedic surgeon to require rotator cuff repair, a knee brace, or spinal injections — sometimes all three.

10. Dermatology: Physically Untouched (But Still Stressed)

Typical Body Changes:

Minimal physical wear — primarily outpatient, non-emergency care.

Some hand strain from procedures.

Generally good skin and posture due to low exposure to hospital chaos.

Dermatologists often seem to defy the physical toll of residency. Their skin glows, their joints work, and their stress levels are lower than average — at least physically. But the mental load of spotting melanomas, counseling anxious patients, and balancing cosmetic with medical practice still takes its toll.

Bonus: access to the best skincare on the market certainly helps their outward glow.

11. Pathology: Quiet Bodies, Quiet Damage

Typical Body Changes:

Static positioning and reduced physical activity.

Eye strain from microscope use.

Neck and upper back tightness.

Low vitamin D and reduced cardiovascular activity.

Pathologists avoid the loudest physical stressors of clinical medicine, but they’re not immune to damage. Isolation, darkness, and stillness add up. The body suffers from lack of sunlight, movement, and real-time interaction. Ironically, they may enjoy fewer occupational injuries but risk long-term sedentary health consequences.

12. The Final Truth: The Body Keeps the Score

No matter which specialty you choose, your body will carry the imprint of your training. Your residency will not only shape your knowledge but also sculpt your physical well-being. Years of medical training inevitably alter:

Posture and gait

Hormonal rhythms

Muscle tone

Circadian alignment

Appetite regulation

Spinal health

Chronic pain susceptibility

Skin quality

Fitness engagement

There’s no perfect path — each specialty comes with its unique costs. But being aware of the physical trade-offs can help you plan accordingly. Your medical journey doesn’t have to mean permanent sacrifice. Awareness is your best protection.

13. Self-Defense Tips for Your Body, No Matter the Specialty

Compression gear: Ideal for long surgeries or endless rounds.

Stretching routines: Especially for surgeons, radiologists, and EM physicians.

Scheduled movement: Even 3-5 minute walks every few hours matter.

Hydration reminders: Essential for any specialty with unpredictable schedules.

Blue light glasses: Critical for screen-heavy fields like radiology and pathology.

Meal prep: Reduces reliance on vending machines and fast food.

Physiotherapy consults: For early injury detection and prevention.

Mindful posture checks: Especially important for psychiatry, radiology, and internal medicine.

The best tool in your career won’t be a scalpel, stethoscope, or EHR shortcut. It will be the one thing you carry through every shift, clinic, and call: your physical and mental health.
