As winter tightens its grip, the NHS is issuing urgent guidance about flu symptoms that should never be ignored. While most people recover from influenza with rest and fluids, certain warning signs indicate potentially serious complications requiring immediate medical intervention.
The Three Red Flags You Must Recognise
Healthcare professionals emphasise that these three symptoms in particular warrant prompt medical assessment:
1. Sudden Chest Pain or Breathing Difficulties
If you experience sharp chest pains, struggle to catch your breath, or find yourself gasping for air after minimal exertion, don't dismiss it as 'just part of the flu'. These could be signs of pneumonia or other respiratory complications that need urgent treatment.
2. Confusion or Disorientation
Feeling suddenly confused, disoriented, or experiencing significant changes in mental state isn't normal with flu. This could indicate your body is fighting a severe infection or experiencing complications that affect brain function.
3. Inability to Keep Fluids Down
While nausea can accompany flu, being completely unable to keep water or other fluids down for more than a few hours is dangerous. Dehydration can rapidly worsen your condition and requires medical attention.
Why These Symptoms Demand Action
"These particular symptoms often indicate the flu is developing into something more serious," explains Dr Sarah Jenkins, an NHS GP with over 15 years' experience. "Chest issues might suggest pneumonia, confusion can signal sepsis, and dehydration weakens your body's ability to fight infection."
The NHS advises that vulnerable groups—including elderly individuals, pregnant women, young children, and those with pre-existing conditions like asthma, diabetes, or heart problems—should be particularly vigilant about these warning signs.
When to Seek Emergency Help
Medical professionals recommend calling NHS 111 or visiting urgent care if you experience any of these symptoms. For severe breathing difficulties, intense chest pain, or significant confusion, dial 999 immediately.
"It's always better to be cautious with flu," Dr Jenkins emphasises. "What starts as manageable symptoms can sometimes escalate quickly, especially during peak flu season when viruses are particularly aggressive."
Remember that flu is highly contagious, so if you need medical attention, alert healthcare staff to your symptoms immediately upon arrival to prevent spreading the virus to other vulnerable patients.
