Today my mum told me I should stop drinking tap water because it contains fluoride which is bad for your thyroid. I have a family history of thyroid problems, perhaps this is why I’ve gained weight? Or is it just wishful thinking/excuse making? I've put on 5lbs since I started actively drinking tap water.

Should I go back to carbonated water or has it got all the same crap as soda in it?

But would fluoridey-tap water be enough to make me gain weight?

I’m just really lost and confused, please help :(

In my nutrition studies I can never say that they have taught me that fluoride causes that. Never even heard of it!

Maybe your body is still adjusting from all the water. Im always drinking tap water, and i havent gained any after the orinional couple pounds. I think its just your body holding onto water until it knows youre going to keep giving it more.

The amount of fluoride in tap water by the time it reaches your house is usually pretty small. I doubt such a dose would have much of an effect on you. You could always buy bottle spring water if you're worried about it.

Fluoride can cause health problems, but I'm not sure about how it impacts the thyroid. I would Google this if I were you, but be wary of your sources. Make sure you're getting information from a reputable site.

I have thyroid problems and am on medication for it now for 10 years and i've never read anything or heard from any of the endocrinologist's I've seen about fluoride and thyroid disease. You definitely should see a doc to check for a thyroid problem if your weight gain is unexplained. I would not think that tap water would make you gain 5 lbs. If you were dehydrated for awhile it could just be that your hydrated self weighs a little more and maybe you are retaining some extra water as your body adjusts to the increased water intake. I wouldn't freak out and just monitor it and if you are eating right (no more than 1200 cals) and you still do not see any loss during the next three weeks consider seeing a doctor.

I don't really think it's a concern...what's your sodium intake like?

If you're worried, get a Brita.

But it's been like 3 months since I started so I'm not sure if my body would hold onto the water for that long?

I've been eating better than I did, though I'm obviously not perfect (today I ate nearly 1800 :/), and I exercise a lot more too so I don't understand :/

My sodium was so low I decided to stop tracking it so I could track protein instead :S

As a nutritional counselor who has thyroid disease, I can say, with almost 100% certainty, that this is completely bogus.

Well thanks, so it almost definitely isn't that then :)

This keeps things simple, I don't have to switch my fluid source now :D

If you're worried about your thyroid, have it checked by your doctor. An under active thyroid can lead to weight gain. There are other symptoms, though, so perhaps read up on it and see if it might apply to you.

I have hypothyroidism, but the cause wasn't too much fluoride in my water . Too much fluoride can cause problems, though I'm unaware of how/if it affects the thyroid.

You can drink filtered water (use a Brita pitcher, etc), to help the quality of your tap water.

I'd say the first thing to work on is hitting your calorie goals. Diet is usually what causes weight gain. *sigh* Also, check how much sodium you're consuming. That's another thing people don't always watch that leads to fluid retention.

The EPA agrees with you:

It could merely be water retention. Weight gain is not enough information to present a clear picture at to what the cause may be.

I have never heard that before and tap water is all I drink.

Hypothyroidism is very treatable. If you are worried about it, it's not hard to get checked and get treated.

I have read the suspicion about the flouride, but honestly, I feel that the benefits far outweigh the risks (if those risks are even legit.)

If you gained 5 lbs, just start tracking to see if you ate too much, or didn't work out enough. Try watching your nutrition and exercise before you come to any conclusions. And honestly, 5lbs isn't much. I'm hypothyroid, and I would say that my hormone problems caused a 20-30lb weight gain, not 5 lbs. Even then, the weight gain was caused by my eating habits and inactivity. The inactivity and excessive hunger may have been caused by the thyroid, but there was an element of discipline in my weight problems. I can't speak for everyone who has an under active thyroid, because many of them did gain weight that they could not control, but I'm pretty sure that if I wanted to, I could have prevented some of my weight gain.
