Man, 60, gave himself rare condition after going to ChatGPT for diet advice
The unnamed man, 60, told doctors he was trying to eliminate table salt from his diet, having read about its negative effects.
Chatting with the artificial intelligence (AI) chatbot, he decided to eliminate salt, also known as sodium chloride, from his diet completely.
He conducted a 'personal experiment' by replacing it with sodium bromide, used in the early 20th century to make sedatives, that he had purchased online.
The man, who had no psychiatric history, was taken to the hospital after becoming convinced his neighbour had poisoned him.
A report of the man's case, detailed in the Annals of Internal Medicine, said the patient developed bromism, caused by overexposure to bromide.
The study said: 'In the first 24 hours of admission, he expressed increasing paranoia and auditory and visual hallucinations, which, after attempting to escape, resulted in an involuntary psychiatric hold for grave disability.'
He also suffered insomnia, fatigue, muscle coordination issues and excessive thirst, his doctors noted.
Medics treated the man's condition and discharged him a few weeks later.
The article authors said it is unclear what advice the virtual assistant gave the man, as they cannot access his chat log.
When they asked the app what salt should be replaced with, bromide was among the recommendations.
The bot did note that 'context matters', though did not provide a health warning 'as we presume a medical professional would do', the authors wrote.
When Metro did the same today, bromide is no longer included and instead includes an 'Important Safety Note: Avoid Toxic Alternatives'.
The advice reads: 'A recent medical case made headlines: a man replaced salt with sodium bromide, based on advice from ChatGPT, which led to bromism – a rare and dangerous condition (causing paranoia, psychosis, insomnia, skin issues). He required hospitalisation.
'Bottom line: Never use unverified, off‑label substances like sodium bromide as salt substitutes. Always rely on safe, reputable options and seek medical guidance when in doubt.'
Sodium chloride has been linked to negative health effects, such as raised blood pressure, but health experts stress it is part of a balanced diet.
According to the UK Health Security Agency, bromide is used in water sanitisers for pools and spas. Low-level exposure is unlikely to cause adverse health effects.
People are increasingly using ChatGPT and other AI-powered chatbots for day-to-day advice, from writing emails to planning their monthly budgets.
About one in six Americans have sought medical advice from ChatGPT, according to a recent survey. In the UK, one in five GPs use AI tools.
Studies have shown that ChatGPT can offer incorrect health advice, sometimes citing medical reports that do not exist.
The report authors concluded: 'While it is a tool with much potential to provide a bridge between scientists and the nonacademic population, AI also carries the risk for promulgating decontextualised information. More Trending
'It is highly unlikely that a medical expert would have mentioned sodium bromide when faced with a patient looking for a viable substitute for sodium chloride.'
The tech start-up, which owns ChatGPT, OpenAI, notes in its service terms that the communication tool is not intended for use in diagnosing or treating a health condition.
The company's terms of use state: 'You should not rely on Output from our Services as a sole source of truth or factual information, or as a substitute for professional advice.'

How many steps you really need to do each day, according to your age
Chloe Johnson Published August 12, 2025 2:15pm Updated August 12, 2025 2:15pm Link is copied Comments Hit your 10,000 steps today? It turns out you might not need to. Originating from a hugely successful pedometer marketing campaign launched ahead of the 1964 Tokyo Olympics, the 10,000 steps a day has been a target for many of us to reach for a while now, but is it actually the gold standard you should be working towards? (Picture: Getty) Walking can be a great way to boost heart health and de-stress. The NHS advises 150 minutes of moderate exercise (meaning at an intensity during which you can still talk comfortably) or 75 minutes of vigorous exercise per week (you shouldn't be able to chat with this one). Walking is a great way to help you achieve this, while also not having to pay for a gym membership. So, how many daily steps are recommended for your age group? (Picture: Getty) According to research, 7,000 steps daily is something of a sweet spot for health benefits and it feels a tad more realistic than 10,000 steps, which can take around an hour and forty minutes to complete. But this sweet spot is of course highly dependent on what you do for work, any physical health conditions and also your age. Metro spoke to Holland & Barrett nutritionist Emily Foster, who revealed the recommended number of steps each age group should be taking on a daily basis (Picture: Getty) Emily said that for children and adolescents the recommended minimum for children is 6,000 steps a day but a higher step count - up to 15,000 - might happen naturally due to running around and playing. However, a child is very different from a teen - who may spend more time sitting at school and doing homework - so there's no magic number of steps, 'especially concerning young people where the body is still growing and developing.' The NHS recommends that children and young people get an average of at least 60 minutes of moderate to vigorous physical activity each day (Picture: Getty) So, how many steps should you be taking in your twenties and beyond? Emily suggests that between 8,000-10,000 steps a day is what you should be aiming for. She says: 'This can be challenging for some, for example office workers, and easier for others, such as keen runners, so it's important not to compare too much. Anyone who is living with a medical condition that could affect their level of activity should always check in with a doctor for a tailored recommendation.' Emily also suggests that you should look at balancing your walking with nutrition, adding: 'For example, someone who is regularly hitting 15,000 steps a day will need to eat more calorie dense food than someone who is less active, to ensure the body is effectively fuelled to function throughout the day' (Picture: Getty Images) Emily explains that for older adults, this sweet spot of steps might be a bit lower. 'At 60, many adults begin to slow down their pace of life,' she says. 'As you get older, bones can become more fragile and your fitness may decline, however lots of people enjoy their retirement by keeping active through various sports. In this stage of life, it's therefore important to understand what feels right for you. I'd recommend aiming for somewhere between 6,000 and 8,000 as a minimum, depending on your current levels of activity and general health' (Picture: Getty) But it's not just about hitting those precious step goals. If you're struggling to find the time to get your steps in, it's better to do a little than aim for a higher goal and lose your motivation completely. What matters most, then, isn't the amount of steps but the consistency. Happy walking!

Chikungunya cases double in UK as expert warns 'all it takes is one mosquito bite'
Cases of Chikungunya, a painful, mosquito-borne disease, have more than doubled in the UK. At least 73 cases were reported in the first six months of the year, up from 27 in the same period last year, according to official figures released today. The UK Health Security Agency (UKHSA) said most infected people had travelled to Sri Lanka, India and Mauritius. In London, 43 travellers reported suffering from chikungunya, the highest in the UK. There were 16 cases in the South East, with five in the West Midlands and four in the East of England. None were flagged in Wales and Northern Ireland. The UKHSA also said the first cases of the oropouche virus had been recorded. Oropouche, transmitted by biting midges, causes symptoms resembling those of dengue: high fever, headaches and joint pain. The chikungunya virus was first detected in Tanzania in the 1950s. It's an RNA virus, the chemical family from which the first forms of life are thought to have emerged, which is behind some epidemics. The origin of its name says it all – a word from the local Makonde people which means 'that which bends up', the way people sickened with it contort in pain. Chikungunya virus symptoms The disease is rarely fatal but can cause fever, severe joint pain, fatigue, nausea and patchy red rashes within a few days after the bite. Most people recover within weeks, but may live with joint pain for months. Older patients, newborns and people with preexisting health conditions are the most at risk. How contagious is the chikungunya virus? People can become infected with chikungunya when mosquitoes feed on a sick person and then bite a healthy person. Unlike conditions such as the common cold or coronavirus, the disease is not spread through coughing, sneezing or touching. Which mosquito causes chikungunya? Chikungunya is carried by the Aedes mosquito, otherwise called the 'flower mosquito', which also transmits dengue and Zika. Howard Carter, a bite prevention expert who founded the bug repellent brand Incognito, told Metro: 'Yes, people should be very wary. 'Whenever Brits go abroad, 64% don't take insect repellent with them and bring mosquito-borne diseases back to the UK.' Carter doubts a major outbreak will happen in the UK and stressed people have a 'low chance' of catching the disease. 'However, all it takes is for a mosquito in the UK to bite someone with chikungunya and then you have an outbreak,' he added. The UKHSA stressed that the Aedes mosquito, which thrives in warm, wet climates, won't be calling the UK home anytime soon. We're too dreary and grey for the insect to survive and breed. 'Therefore, there is currently no risk of onward transmission of chikungunya in the UK,' the agency said, referring to the disease spreading from one person to another. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video The virus, sometimes called CHIKV, has been tearing through Africa and Asia for years and has increasingly leapt borders, affecting millions of people across 110 countries. Cases spreading from Indian Ocean islands to Europe, including France and Italy, prompted the World Health Organization in July to call on countries to act. Carter said the uptick is down to climate change, as planet-warming gases are leading to warmer, wetter weather, which mosquitoes thrive in. China has been especially hard hit by an outbreak of the virus. More than 6,000 cases have been reported in Foshan, a city in southern Guangdong, as of July 31, China Central Television reported. The city of 10million has been asked to take part in a 'patriotic public health campaign' to curb the spread, such as chucking out all stagnant water from flower pots, coffee machines or buckets. Quarantine zones covered in netting, mosquito hunting- drones whizzing overhead and masked soldiers spraying insecticide are now a daily occurrence. 'Everyone is primarily responsible for their own health,' one of the campaign's slogans says. Officials are building 'mosquito factories' to breed hundreds of millions of elephant mosquitoes, whose larvae prey on the virus-carrying mosquitoes. On Weibo, a Chinese social media app, users have described panic-spraying their arms and legs with mosquito repellent, wary as they walk past puddles and rivers. 'I do not dare to wear shorts,' one user who recently returned from Shenzen said. Another added: 'Every day is either a rainstorm warning, a typhoon warning or chikungunya fever.' More Trending One local from Zhejiang, an eastern province, uploaded footage of four frogs nibbling on mosquitoes buzzing around them. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video 'The Four Saints of the Toad Clan guard the Demonic Abyss!' the Weibo user, a technologist blogger, said. 'To prevent chikungunya fever, it is better to use ecological prevention instead of building mosquito factories.' For those wary of a repeat of the coronavirus pandemic, two vaccines for the virus have already been approved for UK use. IXCHIQ and Vimkunya can be purchased privately from travel clinics. Carter recommended to Metro that travellers use his 'CLOAK' method: C – Cover up arms and legs with suitable clothing. L – Light coloured clothes are strongly advisable because mosquitoes are attracted to dark colours. O – Odours, bodily or ordinary scented washing products and perfumes can be strong attractants. So wash with citronella or other repellent shower gels, shampoo and soaps. If you are a mosquito magnet, exfoliate with a loofah. A – Apply an effective, preferably natural, insect repellent containing PMD (or p-Menthane-3,8-diol, a synthesised lemon eucalyptus oil which is a natural repellent). K – Keep away from stagnant water if possible. Get in touch with our news team by emailing us at webnews@ For more stories like this, check our news page. MORE: What is AI psychosis?

The 10 signs of ‘brain swelling' sloth fever which could be spread by sex after cases spotted in UK for the first time
Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) THE UK has reported its first-ever cases of flu-like 'sloth fever'. Three people tested positive for the disease, officially called Oropouche virus, between January and June 2025, new data from the UK Health Security Agency (UKHSA) says. Sign up for Scottish Sun newsletter Sign up 4 Little is known about Oropouche, also called 'sloth fever' Credit: Getty 4 Despite the name, the disease is spread via mosquito Credit: Getty The little-known virus, spread to humans by mosquitoes and biting midges - unlike the name suggests - was also reported in Europe last summer for the first time after it started spreading rapidly in Latin America. Historically, Oropouche was confined to within the Amazon basin in South America, including Brazil, Peru, Argentina, Bolivia, Colombia, and Panama. In 2024, outbreaks also appeared in these regions as well as in Cuba and Barbados, the likely source of some of the 19 cases of sloth fever reported in Europe last year. The first cases of the oropouche in the UK were all linked to travel from Brazil, the UKHSA said. The bug typically circulates between primates, including sloths - hence the nickname - before it is occasionally passed to humans by the critters. Mosquitos and midges found in the UK and wider Europe do not currently spread Oropouche virus disease. Until last year, experts didn't think the virus could spread from person to person. But a study published by Italian scientists in December suggested it could spread in semen, sparking concerns about possible sexual transmission. Scientists are currently investigating whether the infection can be passed on from mothers to babies during pregnancy, after the virus was linked to stillbirths and birth defects. For most people, Oropouche infections are mild, with symptoms typically showing up 4 to 8 days after a bite. I tried the best ways to stop mosquitoes on your summer hols - from sprays, patches & bracelets, one was a dud and stank These can include: Fever Headache Joint pain Muscle aches Chills Nausea and vomiting Rash Sensitivity to light Dizziness Pain behind the eyes UKHSA chiefs have urged anyone who becomes unwell with these symptoms after travel to affected areas. Symptoms typically last less than a week but can occasionally reoccur. In severe cases, the virus can also attack the brain leading to meningitis or encephalitis, which can be fatal. 4 4 It is estimated that fewer than four per cent of patients will develop neurological symptoms. The first ever deaths linked to the virus were reported in Brazil in July 2024, where, sadly, two people died. There are currently no specific antiviral treatments or vaccines available. Treatment for symptoms can include rest, fluids, and the use of medicines to reduce pain and fever.
