What Does a Primary Care Doctor Do? A Complete Guide to Primary Care Services
If you’ve ever wondered “what does a primary care doctor do?” or “what do primary care physicians do?”—you’re not alone. Many people don’t fully understand the scope of care that primary care doctors provide. They’re not just there to treat you when you’re sick. Primary care physicians are comprehensive health advocates who manage everything from preventing illness to coordinating complex medical care.
In this guide, we’ll break down exactly what primary care doctors do, the full range of services they provide, and why having a primary care doctor is one of the best decisions you can make for your health.
What Are Primary Care Doctors?
What are primary care doctors? At their core, primary care doctors are your health’s first line of defense. They serve as your healthcare “home base”—the central point where you manage most of your medical needs and get referrals to specialists when necessary.
Primary care doctors include:
- Family medicine physicians – Care for patients of all ages, from infants to seniors
- Internal medicine doctors (internists) – Specialize in adult care
- Pediatricians – Specialize in children’s health
- Nurse practitioners and physician assistants – Provide comparable primary care services with advanced training
- OB-GYNs – Some women use their gynecologist as their primary care provider
Think of your primary care doctor as the quarterback of your healthcare team. They know your medical history, coordinate your care, manage your medications, and connect you with specialists when you need them.
What Does a Primary Care Physician Do? Core Services Explained
What do primary care doctors do? The answer is: quite a lot. Here are the main services and responsibilities primary care doctors handle:
1. Preventive Care and Health Screenings
Preventive care is perhaps the most important thing a primary care doctor does. Rather than waiting until you’re sick, preventive care focuses on keeping you healthy.
Your primary care physician provides:
Annual wellness visits and physical exams – Comprehensive checkups that establish your baseline health status and identify potential issues early.
Age-appropriate health screenings – Your doctor recommends screenings based on your age, gender, and family history. This includes mammograms, colonoscopies, blood pressure checks, cholesterol screening, diabetes screening, and cancer screenings.
Vaccinations and immunizations – Staying current on vaccines like flu shots, pneumonia vaccines, and other preventive immunizations.
Health counseling – Guidance on nutrition, exercise, weight management, sleep, and lifestyle changes to prevent disease.
Lab work and blood tests – Regular testing to monitor your cholesterol, blood sugar, kidney function, and other important health markers.
The beauty of preventive care? Catching problems early when they’re easier and cheaper to treat. A simple blood test during your annual checkup might reveal high cholesterol or pre-diabetes—conditions you can manage now rather than treating a heart attack later.
2. Diagnosis and Treatment of Common Illnesses
When you get sick, your primary care doctor is your first stop for diagnosis and treatment.
What do primary care physicians do when you’re ill? They treat:
- Respiratory infections – Common cold, flu, bronchitis, pneumonia
- Sore throats and ear infections – Strep throat and other bacterial or viral infections
- Stomach and digestive issues – Nausea, vomiting, diarrhea, constipation, abdominal pain
- Skin conditions – Rashes, infections, eczema, acne
- Minor injuries – Sprains, strains, cuts, bruises
- Headaches and migraines – Both tension and migraine headaches
- Urinary tract infections – UTIs and other urological issues
- Allergies – Seasonal and environmental allergies
Your doctor diagnoses these conditions through physical examination, patient history, and sometimes lab tests or imaging. They then prescribe appropriate treatment, which might include antibiotics, anti-inflammatory medications, or other therapeutics.
3. Chronic Disease Management
For patients with ongoing health conditions, primary care doctors play a crucial role in long-term management.
Common chronic conditions managed by primary care doctors include:
- Diabetes – Both type 1 and type 2 diabetes require regular monitoring, medication adjustments, and lifestyle counseling
- High blood pressure (hypertension) – Monitoring and medication management to prevent heart disease and stroke
- High cholesterol – Managing through medication and lifestyle changes to reduce cardiovascular risk
- Heart disease – Ongoing management and coordination with cardiologists
- Asthma – Monitoring control, adjusting inhalers and medications
- COPD – Managing chronic obstructive pulmonary disease
- Arthritis – Pain management and treatment plans
- Obesity – Weight management and lifestyle modification programs
For chronic conditions, your primary care doctor:
- Monitors your condition through regular appointments
- Orders appropriate tests and screenings
- Prescribes and adjusts medications
- Tracks your progress toward health goals
- Coordinates with specialists if needed
- Ensures you’re following a sustainable treatment plan
4. Medication Management
Managing medications is a critical responsibility of primary care doctors.
Your primary care physician:
Prescribes medications – Based on your diagnosis and health history, your doctor prescribes appropriate medications to treat acute illness or manage chronic conditions.
Monitors medication effectiveness – Your doctor checks whether medications are working as intended and whether side effects are manageable.
Prevents dangerous drug interactions – Since your primary care doctor has a complete list of all your medications (including over-the-counter drugs and supplements), they can identify potentially dangerous interactions before they occur.
Adjusts doses and medications – As your health changes or medications lose effectiveness, your doctor makes appropriate adjustments.
Reviews and deprescribes when necessary – Your doctor periodically reviews whether you still need each medication, discontinuing those that are no longer beneficial or causing harm.
This comprehensive medication management prevents serious adverse events and optimizes your medication regimen for your specific needs.
5. Mental Health Support and Screening
Primary care doctors recognize that mental health is just as important as physical health.
Your primary care physician can:
Screen for depression and anxiety – Many people experience depression or anxiety without realizing it. Your doctor screens for these conditions during visits.
Provide basic counseling and support – Your doctor listens to your concerns, offers perspective, and provides emotional support.
Prescribe mental health medications – Your doctor can prescribe antidepressants, anti-anxiety medications, and other psychiatric medications.
Refer to mental health specialists – For complex mental health conditions, your doctor connects you with psychiatrists, therapists, or counselors.
Address stress and lifestyle factors – Your doctor discusses stress management, sleep problems, and lifestyle changes that affect mental health.
Many people find it easier to discuss mental health concerns with their primary care doctor first, who can then coordinate more specialized care if needed.
6. Specialist Referrals and Care Coordination
Primary care doctors serve as the hub of your healthcare team.
When you need specialized care, your primary care doctor:
Provides referrals – Your doctor refers you to appropriate specialists based on your condition and insurance requirements.
Coordinates care – Your primary care doctor communicates with specialists, ensuring everyone knows your complete medical picture.
Reviews specialist recommendations – Your doctor reviews what specialists recommend and ensures it aligns with your overall healthcare goals.
Manages your overall health – Even when seeing multiple specialists, your primary care doctor ensures that all treatments work together effectively.
Manages specialist-prescribed medications – Your primary care doctor monitors medications prescribed by specialists and watches for interactions with your other medications.
This coordination prevents gaps in care, reduces redundant testing, and ensures your treatment plan is cohesive.
7. Patient Education and Health Coaching
Primary care doctors are educators who help you understand your health and make informed decisions.
Your doctor:
Explains diagnoses – When you’re diagnosed with a condition, your doctor explains what it is, how it develops, and what you can expect.
Discusses treatment options – Your doctor reviews available treatments and helps you understand pros and cons of each option.
Teaches disease self-management – For chronic conditions like diabetes or asthma, your doctor teaches you how to manage your condition daily.
Provides preventive health advice – Your doctor counsels you on nutrition, exercise, smoking cessation, alcohol use, and other lifestyle factors that impact health.
Answers your questions – No topic is off-limits. Your doctor is there to answer any health-related questions.
8. Women’s and Men’s Health Services
Primary care doctors address health concerns specific to different populations.
For women:
- Reproductive health counseling and contraception options
- Prenatal care (in some cases)
- Menopause management
- Breast health screening and counseling
For men:
- Prostate health screening and management

9. Preventive Procedures
Some primary care doctors perform minor procedures in the office:
- Skin biopsies – Removing and testing abnormal skin growths
- Joint injections – Injecting medication into arthritic joints for pain relief
- Wound care – Treating and closing minor lacerations
- Earwax removal – Removing impacted earwax
- Nail removal – Removing ingrown toenails
These in-office procedures save you the cost and hassle of going to a specialist or emergency room.
