What Is Flu?

Flu, or Influenza,  is a viral infection that causes a range of symptoms of varying severity, predominantly affecting the upper and lower respiratory tracts. It spreads easily through respiratory droplets created when coughing or sneezing and is common during the colder months. Although many people recover within a week, influenza can be serious for young children, older adults and people with weakened immune systems.

Unlike the common cold, flu symptoms usually appear suddenly. As a result, people often feel much worse and need proper rest and care.

Common Flu Symptoms

Flu symptoms can range from mild to severe, most people experience several symptoms.
  • Fever or chills
  • Sore throat
  • Cough
  • Runny or blocked nose
  • Body aches
  • Headaches
  • Fatigue
  • Occasional vomiting and/or diarrhoea

Flu Treatment

Most cases of flu improve with rest and supportive care. Still, some people may need medical flu treatment to prevent complications.

  • We often recommend:
  • Resting at home
  • Drinking plenty of fluids
  • Taking fever-reducing medication
  • Using pain relief for headaches and body aches
  • Monitoring flu symptoms closely
  • In some cases, antiviral medication may help reduce the severity of flu. This works best when started early.

Home Remedies For Flu

Simple flu home remedies can help ease flu symptoms and support recovery.

These Include:

  • Warm tea with honey for sore throats
  • Warm water mixed with raw ginger, garlic and lemon
  • Steam inhalation for congestion
  • Adequate sleep
  • Staying hydrated
  • Although home remedies may provide relief, ongoing or severe flu symptoms should always be discussed with a doctor.

When To See A Doctor

Some flu symptoms need medical attention. Speak to a doctor if you experience:

  • Difficulty breathing
  • Chest pain
  • Severe dehydration
  • High fever
  • Confusion
  • Symptoms that worsen

Children, elderly patients, and people with chronic conditions should seek advice sooner.
