Water fluoridation above a certain level is linked to 30 percent higher than expected rates of underactive thyroid (hypothyroidism) in England, suggests research. Researchers point out that their findings echo those of previous research, and that while they were only able to look at diagnosed hypothyroidism, there might also be other cases of impaired thyroid function that have not yet been diagnosed–and treated.
