Obesity fuelling UK's sleep problems as apnoea cases soar by 214% in decade
Analysis of NHS data in England and Wales between 2014 and 2024 revealed a sharp rise in diagnosed cases of the condition.
The figures showed there were 114,640 cases reported across NHS trusts in 2014. But by 2024, this had risen to 360,070, marking a 214 per cent increase in diagnoses over the last decade.
The data, obtained by The Odd Company through Freedom of Information requests, showed cases rose on average by 13.69 per cent year-on-year, with over 2 million cases diagnosed overall in the period.
Sleep apnoea is a sleep disorder that causes repeated breathing interruptions during sleep.
As well as resulting in ongoing tiredness, if left untreated, it can potentially cause various health conditions, including heart disease, diabetes and depression.
Dr David Garley, director of The Better Sleep Clinic, explained: 'It's a disorder of the upper airway where it repeatedly closes as you sleep.
'Your upper airway is held open by muscles, so as you fall asleep your airway naturally narrows in on itself. The first thing you find is the airflow gets turbulent, so that makes the soft structures vibrate, which is snoring.
'But with sleep apnoea, it actually closes and you have this period of not breathing. Your body will only tolerate this for a period of time before it actually has to wake you up and pull you back from the deep state of sleep, into a shallow state or completely awake. So you get really fragmented, poor quality sleep.'
He said one of the main factors in sleep apnoea is obesity, which is also on the rise in the UK.
'Anyone can get sleep apnoea, but the biggest risk factors are age and carrying extra weight - and both of these factors are increasing in the UK and that's why obstructive sleep apnoea is on the increase,' he told The Independent.
'What you're looking at is the collapsibility of the upper airway, so this happens because the muscles relax as you fall asleep. If you've got more weight around your neck, it just pushes in a bit more.
'Menopause is another risk factor. That's often to do with the redistribution of weight in the body as you go through that transition, so you tend to get a bit more around that area which pushes in.'
He added that 85 per cent of people who have sleep apnoea are undiagnosed due to the difficulties in knowing whether they are displaying symptoms.
Some of the rise in diagnoses could also be thanks to an increase in awareness of the condition.

He said: 'Hopefully some of it is because we're eating into that 85 per cent, but inevitably it's because more people will have sleep apnoea.
'Some of the increase is because of awareness, and others is because undeniably there are more old people and obesity is a bigger issue.'
According to the NHS, sleep apnoea can sometimes be treated by making lifestyle changes like losing weight, giving up smoking and reducing alcohol consumption.
But many people need to use a device called a CPAP machine, which gently pumps air into a mask worn over the mouth or nose during sleep.
The government is planning a wave of new measures to reduce levels of obesity, after the Office for Health Improvement and Disparities estimated that more than a quarter of the English population is now obese. Rates of obesity have doubled since the 1990s, costing the NHS an estimated £11 billion a year, which is three times the annual budget for the ambulance services.
Health secretary Wes Streeting has warned that, unless the 'rising tide of cost and demand' is curbed, the NHS 'risks becoming unsustainable'.
Ministers are also planning regulations for restaurants to monitor diners' calorie intake and drive it down further.

NHS nurses set to join doctors' miserable 5-day walk out after ‘rejecting latest pay deal'
NURSES are poised to reject a pay rise from the Government- paving the way for fresh NHS strike chaos. The Royal College of Nursing is understood to have 'overwhelmingly' voted down the 3.6 per cent offer in an indicative ballot, warning it will be 'entirely swallowed up by inflation'. 2 2 But while the majority backed action, turnout fell short of the 50 per cent legal threshold needed to trigger a walkout. It means more disruption may still be on the cards if the union pushes for a full vote. A union spokesman said: 'The results will be announced to our members later this week. As the largest part of the NHS workforce, nursing staff do not feel valued and the government must urgently begin to turn that around.' It comes as thousands of resident doctors in England, previously known as junior doctors, kicked off a five-day strike on Friday after pay talks between the Government and the British Medical Association collapsed. Health Secretary Wes Streeting said disruption to the NHS was not possible to eliminate but insisted it was being kept to a minimum. The RCN represents hundreds of thousands of frontline nurses across England, Wales and Northern Ireland. Scotland's nurses have already accepted a separate two-year deal worth 8 per cent, keeping them the best-paid in the UK. Nurses were offered less than almost every other public sector group this year. Doctors, teachers, armed forces and prison officers are all getting more. RCN boss Prof Nicola Ranger has led calls for fairer pay and warned that ministers are ignoring a growing crisis in the profession. She fumed last month: 'Nursing is an incredible career, but despite being the most valued profession by the public we continue to be weighted to the bottom of the NHS pay scale.' Speaking at a global conference in Helsinki, she added: 'I'm with nurses from around the world asking why it is our ministers in the UK who have once again put nursing at the back of the queue when it comes to pay.' More than 26,000 nurse roles are currently vacant, with student recruitment collapsing and resignations 'skyrocketing', the union says. Nurses made history in winter 2022-23 by walking out for the first time ever - holding four separate two-day strikes. But the RCN failed to secure a new strike mandate in 2023 after a re-ballot missed the 50 per cent turnout threshold. Members have now rejected three government offers in a row: 5 per cent in 2023-24, 5.5 per cent last year, and now 3.6 per cent for 2025.

York man with rare blood type makes 100th donation
A man with a rare blood type who made his 100th donation this year is encouraging others to give Boocock, from York, has been donating his rare B-negative blood for 40 years, after being inspired by his uncle, also a long-term 61-year-old is one of fewer than 20,000 B-negative blood donors in England, according to NHS Blood and NHS said it had lost almost 1,000 B-negative donors in the last year - or 5% of the B-negative donor base. When Mr Boocock was 21 and working for his uncle, he asked why he would regularly donate blood."I hadn't realised that when I was quite young, my auntie had an operation that went slightly wrong, and she needed over 20 units of blood to make it through," he said."That got me thinking, that's 20 people that can only donate once every few months."I thought, I've got spare in my body, so why don't I volunteer?" 'Not going to stop' By donating over the years, Mr Boocock found out that his blood was suitable for newborns, who can only be transfused with blood lacking cytomegalovirus (CMV), a mild and common virus that most people catch as a child."Occasionally when I donate, they say this one will be going to the neonatal ward," the donor said."That's quite a nice thought that it's going straight to a little baby perhaps that doesn't know they need it."The NHS has appealed for younger donors to give blood, as up to 200,000 new donors are needed each year to replace those who stop donating. "I liken donating blood to a bank account, basically," Mr Boocock said."Unless you put some in, how could you rely on there being some there when you may need it?"After 73 donations, his uncle had to stop for health reasons - which encouraged Mr Boocock to keep going."Once I passed that, I thought, I'm not going to stop now. Let's see how many I can keep going with, until I no longer can," he said."Hopefully that will be for many years to come."

Is it true that … natural salt is healthier than table salt?
Flaky sea salt, pink rock salt, fleur de sel … Thanks to a generation of TV chefs sprinkling gourmet seasonings on dishes with flair, it feels instinctive that these natural, premium versions of sodium chloride are somehow healthier than humble table salt. And many of them market themselves that way – claiming that lower levels of processing and higher levels of minerals like potassium and magnesium make them the superior choice. But Sonia Pombo, a registered nutritionist and head of research and impact at Action on Salt, disagrees. 'The evidence linking a high intake of salt to raised blood pressure is very well documented,' she says. (Overconsumption is also linked to an increased risk of stomach cancer, osteoporosis and kidney problems.) 'Some of these companies may try to convince the public they're better,' she says. 'But if you look at the tiny amounts of magnesium or potassium in these salts, it's laughable. If you want micronutrients, eat a piece of fruit.' The benefits of electrolytes, too, are often overstated, she says. Saline drinks can be helpful if you're recovering from a stomach bug or training like an elite athlete on a restricted salt diet. But for most of us? 'They're not really necessary – we're already eating too much salt.' In the UK, adults are advised to consume no more than six grams of salt a day. The most recent figures show we eat 40% more than that – but even six grams isn't a target to aim for, Pombo says. 'We can survive and thrive on as little as one gram per day.' If you're worried about how much salt you use, the only 'better' kind is low-sodium salt. The real answer is to gradually reduce consumption – slowly, so you don't notice the difference. Cook at home more often and beware of hidden salt in products like bread and sauces.
