Mineral Water whilst on a Chemo??

Does anyone have any information/advice on the type of water you should or should not drink whilst on chemotherapy?

A friend of mine was told by her oncologist not to drink mineral water, but only to have tap water! I would have thought it would be the other way around?!

Has anyone had any advice from their oncologist regarding this?

Bottled mineral water is supposed to be more likely to contain bacteria whereas tap water does not, I think this is the reason.


What type of water was never mentioned to me, just to drink

Lots yo stop dehydration. I stuck with good old fashioned tap water. Ann xo


It was never mentioned to me and I drank both tap (from filter) and bottled water and don't think I suffered from it. Good luck

It'll be the chance of infection I expect but 'mineral' water also has higher mineral content which varies between makes. I only ever drink tap water but it tastes good where I live anyway. It does vary. Plenty of it is the main thing. I'm on avastin maintenance and I have at least 3 litres a day.


Mineral water is carbonated, that may be the reason for being restricted I will guess.


I would have thought it was because mineral water has a high calcium content which can show up in your bloods. I drink both but not allowed take calcium tablets or any medication with calcium in it. Hope this helps


Thank you everyone for all the replies, I think I may stick to tap water until I see my oncologist next week, then ask him the question, though I am not hopeful of an informed response!!!!

I am amazed at how much water some of you are drinking, I drink as much as possible, but I would be swimming if I drank 3 litres a day!!!!!

Thank you again x


Tap water is better for you apparently, for lots of reasons including the chemicals in the plastic bottles for mineral water and the lack of fluoride etc - cheaper too lol
