You may blame your hormones – and your chromosomes – for a way your physique reacts to and fights sure infections, illnesses and illnesses
We’re all created equal, after all. However one medical fact we
can’t keep away from is that the intercourse we’re born with can decide the best way we expertise sure sicknesses. The truth is, a rising physique of analysis is exploring the various signs women and men can develop to the identical health problem.
Migraines and complications
A staggering one in 5 British girls experience regular migraines, in contrast with one in 15 males. And whereas we don’t know precisely why, we do know what triggers them is totally different, says Dr Jeff Foster, a London GP and males’s well being specialist. “Males usually tend to expertise migraines after strenuous bodily labour, whereas girls usually tend to develop them in response to nighttime shifts, lack of sleep or irregular sleep patterns,” he says. “Triggers might embody dehydration and caffeine, so not consuming sufficient water whenever you’re doing bodily labour and consuming an excessive amount of coffee on evening shift. However nobody is aware of why for sure.”
Hormones can also play an element, says Dr Colin Michie, deputy head of drugs on the College of Central Lancashire. “A dip in oestrogen can deliver on a headache or migraine, which is why extra girls may expertise them round their menstrual cycles, in the beginning of the menopause [perimenopause] or after a hysterectomy.”
Colds and flu
Scientists have unlocked various potential causes flu generally – together with Covid – impacts women and men in a different way, although they’re nonetheless being researched.
Firstly, males’s lungs have extra of a particular sort of receptor which impacts how the an infection takes maintain. “Extreme Covid an infection happens by binding to a protein in our our bodies referred to as the angiotensin-converting enzyme 2 (ACE2) receptor,” says Michie. “Males have extra of those receptors of their lungs, giving the virus extra of an opportunity to take extreme maintain.”
Secondly, X chromosomes (of which girls have two and males one) comprise numerous genes associated to immune operate. “Girls usually tend to have extra strong expression of those genes and to supply extra immune elements, like what are referred to as ‘interferons’, that are pure antiviral proteins,” says Dr Stathis Giotis, a lecturer in molecular virology on the College of Essex.
Thirdly, hormones. “Girls have oestrogens which have an immunoprotective impact, whereas androgens most likely suppress the immune system,” says Giotis. “That’s why girls might clear the virus extra simply than males.”
Briefly, the dampening impact of testosterone on the immune system might make males extra vulnerable to viral infections like flu and extra critical signs – which suggests “man flu” is prone to be a factor – whereas oestrogen may need a protecting impact, making girls’s signs milder.

Pores and skin issues
“Girls have gotten way more complicated hormonal patterns due to our menstrual cycles, being pregnant, the contraceptive tablet and even menopause, and that’s a set off,” says Dr Anjali Mahto, a guide dermatologist at Self Clinic London. Stress may stimulate the secretion of drugs that activate oil glands in the skin of individuals with zits to supply extra sebum, resulting in pimples. Through the teenage years, males are , however from in regards to the age of 23 onwards, grownup zits is extra widespread in girls, affecting about 40 per cent of ladies and solely 8 per cent of males, says Mahto.
Whereas pores and skin most cancers impacts the identical variety of males as girls, it’s rising sooner within the former, with male instances having tripled for the reason that early Nineties. “Males aren’t pretty much as good with making use of sunscreen,” says Mahto. In males, the commonest website for pores and skin cancers to develop is the again, whereas in girls it’s the decrease legs. “Girls are good at making use of sunscreen to their faces, however most will overlook it on their legs. Likewise, males are much less prone to ask for assist placing sunscreen on their backs. In order that they’re two areas the place high-intensity sunburns can happen – particularly on holidays within the stronger solar.”

Blood strain and coronary heart issues
Males usually have higher blood pressure than girls. “One of many causes is as a result of oestrogen has a protecting impact,” says Foster. “That’s why after menopause when oestrogen ranges drop, girls’s ranges of hypertension [high blood pressure] meet up with males’s.”
Males even have twice as many coronary heart assaults than girls. “The primary way of life elements that put you in danger, together with smoking, alcohol and central obesity, are all better in males,” says Foster. “And whereas their ldl cholesterol can also be increased than girls’s, they’re much less prone to get themselves checked till after one thing goes mistaken, which is commonly the case.”
Males’s and ladies’s hearts are totally different sizes too which might additionally play an element in how they expertise coronary heart issues, says Michie. “The typical weight of a male coronary heart is 331 grams and a feminine’s is round 245g, and so they’re often a unique form,” he says. The truth is, a scientific assessment evaluating female and male hearts in 2022 concluded feminine hearts not solely beat sooner and have decrease blood strain, they’re additionally structured in a different way. But most medical analysis is completed on males’s hearts, as soon as once more emphasising the necessity for sex-specific medical research with the intention to “higher perceive the feminine coronary heart”.
