Causes
Main causes
- Flu is caused by influenza viruses, which spread when someone who is sick coughs, sneezes, or talks.
- You can also get the flu by touching surfaces that have the virus and then touching your mouth, nose, or eyes.
Risk factors
- Being near someone who has the flu
- Not getting a yearly flu vaccine
- Being very young or over 65
- Living in a care facility or crowded setting
- Having chronic conditions like asthma, heart disease, or diabetes
- Having a weakened immune system
When to see a doctor
See a doctor urgently if:
- If you have flu-like symptoms and a procedure is scheduled within the next few days, call your doctor or the surgical center immediately.
- If you have severe symptoms like trouble breathing, chest pain, or confusion, get emergency care right away.
Book a routine appointment if:
- If you think you have the flu and do not have an upcoming procedure, consider contacting your doctor for advice, especially if you are in a high-risk group.
Diagnosis
Doctors usually diagnose flu based on your symptoms and a physical exam. Sometimes they use a swab from your nose or throat to confirm it.
Tests that may be done
- Rapid influenza test (nose or throat swab)
- PCR test, which is more accurate and may be done in certain cases
What to expect at your appointment
Your doctor will ask about your symptoms, any recent exposure to flu, and your health history. If you have a scheduled procedure, the care team will also ask about your symptoms to decide if it is safe to proceed.
Treatment
Treatment for flu focuses on relieving symptoms and letting your immune system fight the virus. Antibiotics do not work against flu. Antiviral medicines may be prescribed in some cases, especially for those at higher risk, if started early.
Self-care at home
- Rest as much as possible and stay home from work or school
- Drink plenty of fluids such as water, broth, or clear soups to prevent dehydration
- Use a cool-mist humidifier or take a warm shower to ease cough or congestion
- Sip warm tea with honey for a sore throat
- Avoid close contact with others to stop spreading the virus
Medical treatments
Your healthcare provider may recommend an antiviral medicine if you are at high risk or if you are admitted to the hospital. Pain relievers such as paracetamol or ibuprofen can help with fever and aches, but always ask your doctor or pharmacist which products are safe for you.
When is surgery considered?
If you have the flu, elective (non-urgent) surgeries or procedures are often postponed until you have fully recovered. This reduces risks like breathing problems, pneumonia, and slower healing. Your care team will let you know when it is safe to reschedule.
Living with this condition
While you have flu, take it easy. Stay home, limit visitors, and focus on rest and fluids. Use tissues for coughs and sneezes, throw them away immediately, and wash your hands often.
Lifestyle tips
- Avoid alcohol and tobacco smoke during recovery
- Keep your home warm and comfortable, but ventilate the room regularly
- Use over-the-counter remedies only after checking with a pharmacist or doctor
- Surfaces like doorknobs, phones, and counters should be cleaned frequently
Diet and exercise
You may not feel like eating, but try small meals and clear fluids. Avoid intense exercise until your fever is gone and you feel stronger. Gentle moving around the house is fine.
Mental health and emotional wellbeing
Being sick and missing a procedure can be stressful and disappointing. It is normal to feel anxious or frustrated. Talk to your care team about your worries, and ask for support from family, friends, or a therapist if needed.
Prevention
Yes, you can reduce your risk of getting the flu by washing your hands often, avoiding touching your face, and staying away from sick people. Getting a yearly flu vaccine is the best preventive step.
Vaccines
The seasonal flu vaccine is recommended for nearly everyone aged 6 months and older. It is especially important for adults over 65, young children, pregnant people, and those with chronic health conditions.
Screening programmes
There is no routine screening for flu, but if you have an upcoming procedure, your care team may ask about symptoms and do a quick test if needed.
Complications
If left untreated
- Pneumonia (an infection in the lungs)
- Worsening of existing conditions like asthma or heart failure
- Ear infections in children
- Sinus infections
- Dehydration
Long-term outlook
Most people recover from flu within one to two weeks with rest and fluids. For a scheduled procedure, rescheduling for a later date is safe and common. With the right care, your health and your procedure can get back on track.
