Many people see a doctor only when something goes seriously wrong. They wait for a fever to pass, a cough to disappear or pain to ease, and often it does. But some symptoms are warnings that something needs attention, and some conditions, such as high blood pressure, diabetes or early cancer, cause no symptoms at all until they have already done damage. A general physician (GP) or family doctor is the right first point of contact for most health concerns. Knowing when to visit one, and when to go straight to the emergency department, saves time, money and sometimes lives.
This guide explains what a general physician does, which symptoms should prompt a visit, which situations call for emergency care, how to prepare for an appointment and how regular check-ups keep you healthy.
What Does a General Physician Do?
A general physician, also called an internist or family doctor, is trained to diagnose and treat a wide range of illnesses in adults. They are often the first doctor you see, and they:
- Assess new symptoms and find likely causes.
- Treat common infections and everyday conditions such as fever, cough, diarrhoea, urinary infections and skin problems.
- Manage long-term illnesses such as diabetes, hypertension, thyroid disease, asthma and arthritis.
- Order tests and interpret results.
- Provide preventive care including vaccinations, screening and lifestyle advice.
- Coordinate care with specialists when needed, and keep track of your overall health.
- Review medicines to avoid harmful combinations and unnecessary prescriptions.
Having one doctor who knows your history saves time and improves safety, because they see the whole picture rather than a single symptom.

When to Go to the Emergency Department Instead
Do not wait for a doctor's appointment if you or someone else has:
- Chest pain or pressure, especially with sweating, nausea or pain spreading to the arm or jaw.
- Sudden weakness or numbness on one side, drooping face, confusion or speech difficulty.
- Severe difficulty in breathing, or blue lips.
- Heavy bleeding or vomiting blood.
- Fainting or loss of consciousness.
- Seizures.
- Severe abdominal pain that is sudden or comes with a rigid belly.
- Severe allergic reaction with swelling of the face or throat, wheezing or collapse.
- Head injury with vomiting, drowsiness or confusion.
- Suspected poisoning or overdose.
- High fever in a baby under three months.
- Pregnant women with bleeding, severe pain or reduced baby movements.
How to Prepare for Your Appointment
A little preparation makes the visit more productive.
- 1Write down your symptoms: what they are, when they started, how often they happen, what makes them better or worse, and anything you have tried.
- 2List your medicines and supplements, including doses, and bring the strips or a photo of the labels.
- 3Note your medical history, including past illnesses, surgeries, allergies and family history.
- 4Bring previous reports, scans and prescriptions, in date order.
- 5Prepare your questions, and write them down so you do not forget.
- 6Be honest about habits such as smoking, alcohol, diet and sleep. Your doctor is there to help, not judge.
- 7Bring a family member if you are unwell or want help remembering instructions.
- 8Carry your insurance details and ID.
- 9Ask about fasting if blood tests are planned.
Questions to Ask Your Doctor
- What is the likely cause of my symptoms?
- Do I need any tests, and what will they tell us?
- What treatment do you recommend, and are there alternatives?
- What side effects should I watch for?
- How long before I should feel better?
- When should I come back, and what symptoms should make me return sooner?
- Are there lifestyle changes that could help?
The Value of Regular Check-ups
Many serious diseases are silent in the early stages. Regular check-ups catch them when they are easiest to treat. A sensible schedule for most adults includes:
- Blood pressure: at least once a year, more often if it is high or you have risk factors.
- Blood sugar: every one to three years after age 30 to 35, or yearly if at risk.
- Cholesterol: every one to five years, depending on risk.
- Weight, waist and BMI: at every visit.
- Thyroid, liver, kidney and blood count tests: as advised.
- Vision and dental checks: annually.
- Cancer screening and vaccinations: according to age and sex.
- Mental health review: whenever you feel something is off.
Avoid These Common Mistakes
- Self-medicating with antibiotics. Antibiotics do not work against viral infections and can lead to resistance and side effects.
- Stopping medicines once you feel better, for example antibiotics or blood pressure medicines, without medical advice.
- Searching symptoms online and diagnosing yourself, which often increases anxiety or leads to wrong conclusions.
- Doctor hopping, which fragments your records and can lead to repeated tests or conflicting treatments.
- Ignoring "small" symptoms that persist.
- Taking painkillers regularly without finding the cause.
- Believing that "normal" tests mean you can skip follow-up when symptoms persist.
Telephone and Online Consultations
Many follow-up queries, medicine refills and minor concerns can be handled by phone or video, which saves travel. However, new serious symptoms, anything requiring examination or emergencies need an in-person visit.
How to Describe Your Symptoms Clearly
Doctors diagnose largely from what you tell them, so a clear description saves time and improves accuracy. Use a simple structure: where it is, what it feels like (sharp, dull, burning, pressure), when it started and how it has changed, how long each episode lasts, what brings it on or relieves it, and what else happens with it, such as fever, vomiting or breathlessness. Mention whether you have had it before, whether anyone at home has similar symptoms, and any recent travel, new medicines or changes in diet. Photographs of rashes or swellings, and a log of home blood pressure or sugar readings, are very helpful.
Managing Minor Illnesses at Home
Not every symptom needs an immediate visit. For a common cold, mild sore throat or low-grade fever, rest, fluids, steam, warm saline gargles and paracetamol at the correct dose are enough for most adults. For mild diarrhoea, oral rehydration solution and light food help. For minor sprains, rest, ice, compression and elevation are useful. The rule is to watch the trend: if symptoms are getting worse after two to three days instead of better, if new symptoms appear or if you are in a high-risk group such as pregnancy, diabetes, advanced age or heart disease, see a doctor sooner.
