Fears over fluoridated water have been denied by city health chiefs after a study of Birmingham residents suggested higher levels of thyroid conditions were leading to weight gain and depression.
Researchers investigated GP surgeries in the West Midlands which has the highest levels of water fluoridation in the country.
The team from the Centre for Health Services Studies at the University of Kent found doctors in the region had recorded 30 per cent higher than expected rates of underactive thyroid.
But Birmingham health bosses insisted there were no risks, emphasising this was just ‘one report’ against extensive research over the years – and said the city’s excellent teeth was a key benefit.
Researchers said GPs in the West Midlands were nearly twice as likely to report high hypothyroidism prevalence as Greater Manchester, where it is not added to drinking water.
The report said: “The findings of the study raise particular concerns about the validity of community fluoridation as a safe public health measure.”
Hypothyroidism symptoms can include tiredness, weight gain, mental slowing, and depression.
Nationally, research suggested up to 15,000 people could be suffering needlessly from thyroid problems which can cause depression, weight gain, fatigue and aching muscles.
Lead author Professor Stephen Peckham, from the Centre for Health Service Studies, said: “I think it is concerning for people living in those areas. The difference between the West Midlands, which fluoridates, and Manchester, which doesn’t was particularly striking. There were nearly double the number of cases in Manchester.
“Underactive thyroid is a particularly nasty thing to have and it can lead to other long-term health problems. I do think councils need to think again about putting fluoride in the water. There are far safer ways to improve dental health.”
The thyroid gland, which is found in the neck, regulates the metabolism as well as many other systems in the body. The study, which is published online in the Journal of Epidemiology & Community Health, said the effects of fluoride on the thyroid have long been observed, but there have been no population studies that have examined this.
“The finding of this cross-sectional study has important implications for public health policy in the UK and in other countries where fluoride is added to drinking water or in other forms such as fluoridated milk and salt,” it added................

Why are we still dealing in if's but's and maybe's...Fluoridated water could cause depression surely we have the knowledge and resources to say either it does or does not cause depression...And it's easy to deny something as words are cheap what is needed is the evidence to back the denial up with...Saying this is just one report against extensive research over the years is BS...The York Review was extensive and they found that more high quality study is needed so what research are the health chief's using if the review couldn't find any,that also applies to (PHE) who endorse fluoridation with what must be made up science...
When we know that the fluoridation chemicals have never undergone any toxicological tests proving them safe for human consumption, it is impossible that there could be any credible scientific evidence that fluoridation is safe with no adverse health effects. All PHE's and the pro fluoridation lobby's claims of extensive research is BS, as you observe, Ryan.
