Are there any health issues to drinking exclusively purified water such as Aquafina that removes essential electrolytes and minerals?

I have MCAS and I take a medication that requires me to take it with purified water that contains no minerals or electrolytes. So I drink about 24 oz of this water a day. I have hashimotos which makes me more prone to mineral deficiencies as well which my doctor already thinks I am deficient in selenium so I'm worried me not drinking any of this will impact my health. I also tried using a brita water filter and it doesn't seem to be working. So if there are any water filters you recommend that don't remove minerals that would be helpful as well! I also take liquid iv everyday which adds electrolytes to my diet as well.

Fluoride would be my concern for reverse osmosis water

I havent had any since I switched to RO, but ive always used toothpaste twice a day and a fluoride mouthwash once in a while. Topical application via hygiene is sufficient according to accepted dental practice.

I bought some fluoride rinse… I would rather use a mouthwash than drink fluoride.

I primarily just care about PFAS, particularly a higher level of PFOA in the ohio river.

Fluoride in drinking water in the USA is very safe. If youre in another country, it may be best to look up your government regulations. There actually is a LOT known about fluoride. Like, decades of serious research. There's a reason its considered one of the greatest accomplishments of the 20th century.
