An NHS doctor has weighed in on the long-running debate over whether 'man flu' is a genuine condition or simply an exaggeration of symptoms. According to Dr Jeff Foster, an NHS GP partner and medical director for Men's Health and TRT Specialist at Voy, there is some truth behind the phenomenon.
Biological basis for 'man flu'
Dr Foster explained that research published in the British Medical Journal has suggested men may experience more severe symptoms from respiratory viruses than women, partly due to differences in immune response. He said: "Women tend to have a faster, more aggressive initial immune reaction to viral infections, which may help clear the virus more quickly. Men's immune systems appear to respond differently, which can mean symptoms linger longer and feel more intense."
He added: "Whether that fully explains the man flu mythology is debatable, but it does suggest the biological basis isn't entirely made up."
Other factors at play
However, Dr Foster noted that other biological influences affect how people cope with colds or flu, including age, baseline health, stress levels, sleep quality, and even gut microbiome. As a result, two people exposed to the same bug can have completely different experiences.
When distinguishing between a cold and flu, the speed of onset can be a clue. A common cold may take a couple of days to develop, while flu can hit quickly, potentially leaving someone fine at breakfast and floored by lunchtime.
Symptoms to watch
While many cold and flu symptoms can be treated at home with rest, hydration, and medicines, some require medical attention. Dr Foster outlined five symptoms that should never be ignored:
- Chest pain or tightness
- Difficulty breathing
- Fever above 39.5C
- Confusion
- Symptoms that improve then suddenly get worse
Offering advice ahead of the winter flu season, Dr Foster said: "For most people, the best approach is rest, fluids, and paracetamol or ibuprofen to manage fever and discomfort. Stay home if you can. Autumn and winter viruses spread quickly, and the most effective thing you can do for the people around you is to not share what you've got."
He concluded: "Man flu may be embellished, but the virus underneath it is very much real."
