Fluoride and hypothryrodism

There's some evidence that the amount of fluoride in tap water and toothpaste is enough to push some people into hypothyrodism.

Could people becoming fatter be related to fluoridated water? I've collected theories about obesity, but I've never seen this one before.

I'll look for links if anyone's interested, but from memory-- hypothyroidism is tricky to diagnose, and fat people frequently have a hard time finding doctors who will do more than tell them to lose weight.

Even if fluoridated water causes hyothyroidism and this is bad for people (being fatter may have little or no effect, but lack of exercise is bad for people, and low thyroid lowers energy levels), I have no idea how to balance that against fewer cavities.

Home filters generally don't remove fluoride. Some brands of bottled water down't have fluoride.

"Even if fluoridated water causes hyothyroidism and this is bad for people (being fatter may have little or no effect, but lack of exercise is bad for people, and low thyroid lowers energy levels), I have no idea how to balance that against fewer cavities."

If cavities are the issue, one could avoid sugar, crunchy/salty snacks and carbonated beverages; use a Sonicare toothbrush, floss and use Listerine after every meal; and see one's dentist twice a year.

If low thyroid function is the issue, one could take iodine and/or kelp supplements, along with Vitamin K.

If obesity is the issue, one could cut out refined carbs, processed oils and carbonated beverages; eat eight servings of vegetables or raw whole fruit per day; drink water or unsweetened tea; use small plates and don't take seconds; stretch every day; walk at least half a mile every day (work up to it slowly if necessary) as briskly as possible; go to the pool at least once or twice a week; get a bike, adult trike or stationary bike and ride it often; get up and dance to one dancey Youtube video for every hour online.

A person who does all of the above will have a lot fewer cavities than average, will be more likely to have a healthy thyroid, and will gradually attain a healthy weight and fitness level. Of course, with or without fluoride, there will always be some cavities and some hypothyroidism. And with or without fluoride, there will always be eating disorders, mood disorders and orthopedic or systemic problems that make leading a healthier lifestyle more difficult than it sounds. Fluoride may have some effect, but it's probably miniscule compared to the already-known causes of obesity - the biggest of which is Bad Habit.

Weight gain is one symptom of hypothyroidism, but it's not the main or only one, and thin people can have low thyroid function too. Even if thyroid function is perfectly healthy, someone who sits too much and eats too much of the wrong kind of food will always get fatter and weaker.

Smokers who come to the doctor with a persistent cough and shortness of breath are invariably told to quit smoking, regardless of anything else that might be causing their symptoms, such as pneumonia, lung cancer or congestive heart failure. None of those can be cured by quitting smoking, but they're all definitely exacerbated by continuing to smoke. Not smoking won't guarantee that a person won't get any of them, but it does improve one's chances by a significant margin.

Hypothyrodism has a bunch of symptoms. As I understand it, neglecting them can add up to a bad impact.

I don't know whether iodine effectively counteracts the effects of too much fluoride. What do you think?

If a smoker is told to quit smoking without having symptoms of what might be a serious problem checked out, the results can be deadly.

I've never heard anything about the interaction of iodine and fluoride. Iodine plus Vitamin K is a 'first thing to try' for sluggish thyroid, before getting into the prescription options - sometimes it works; I don't know the mechanism of action though.

True indeed; as noted, quitting smoking will not necessarily cure the diseases caused by smoking, nor prevent a person from developing them. People with cardio-pulmonary disease do need to quit smoking, but also need proper medical care whether they quit smoking or not.

Eating better and exercising more won't necessarily cure Type 2 diabetes, hypertension or metabolic syndrome, but people with those conditions need to do it anyway. They still deserve medical care even if they won't do it, of course. But have some sympathy for the doctors: it's very hard to keep on caring for/about someone who persists in willfully self-destructive behavior while expecting someone else (viz. the doctor) to take away the consequences of their actions.

Note I say "eating better and exercising more", not 'losing weight'. A person who follows the suggestions I mentioned may lose weight, gain weight or stay about the same - what will happen is that their weight will normalize toward their personal optimum as their metabolism gets back into balance. Unfortunately, most GPs and ARPNs are taught almost nothing about nutrition and metabolism, so they think "lose weight" is useful advice, when it's really almost completely useless.

Quitting smoking is much easier than altering one's eating habits. With tobacco, one can just walk away and never look back; never smoke another cigarette, but one can't just quit eating, or live the rest of one's life on lettuce, yogurt and chia seeds either. Quitting smoking forever is also easier than maintaining an exercise program: nobody ever injured themselves throwing their cigarettes away, nor didn't have enough time or energy to not smoke.

Still, sitting too much, eating too much, and eating the wrong kind of food can be just as lethal as three packs of Camels a day. Certainly there's a lot more research establishing that fact, than there is indicating any problem with fluoridation.

For the record, I'd prefer not to have fluoride added to water supplies, because it does cause problems for some people and (unlike chlorine) can't easily be removed. The problem with fluoridating the water is that there's no way to tell how much fluoride any given person is absorbing from one day to the next. I don't have a problem with fluoride toothpaste, though, and I do think children ought to have fluoride tablets while their teeth are developing.

I drink bottled water. I don't even give tap water to my cats. Of course my toothpaste is fluoridated, but I don't swallow it. . . .
