This is something I've also struggled with as long as I can remember. Don't know if stats will be of interest, but for what it's worth I'm 30, female, more active than your average 30yr old (no desk job either), and of normal BMI. I generally eat healthy with a tendency toward little carbs and higher protein content. Warm water is mostly tolerable in small sips strung throughout the day but not a cureall for sure. Today, I drank two ~16oz bottles of water between 9a-5p and toward 3p with 1/2 bottle left to go I started feeling the nausea building. It wears off after 30-60 minutes if I completely stop fluid intake. I also find that sometimes it is accompanied by a headache (the type that creates a feeling of fullness in the head) and sometimes a dull middle back pain (where you'd expect the kidneys to be - but no infection to speak of). I was reading in class today about the urinary system and the adjustment for water and sodium content. Water often follows sodium as far as reabsorption goes. Also, too little water intake triggers ADH (antidiuretic hormone) which triggers the body to put aquaporins into the lining of the nephron tubules and collecting duct to take more water in to the body. If I recall, there was a syndrome where people are ADH/aquaporin deficient and thus cannot retain water. I wonder if there is a similar dysfunction in which the aquaporins cannot be removed. Thereby causing upset with any large amount of water because it over hydrates a person. I don't know if that's worth considering because I think the majority of us seem to tend toward dehydration rather than overhydration, but it's something to mull over perhaps? I do think the electrolyte concept is worth revisiting as well since that is deeply intertwined with water reabsorption. Regarding the psychosomatic concept, I think it's very possible. Psychosomatic issues are largely (and unfairly) dismissed. However, since I've experienced this since I was a young child and even tried correcting it with behavioral cognitive therapy, it's worth my considering it is purely physical. One thing I have noticed is that I don't drink much in general. I almost never get thirsty despite only drinking maybe 2-3 glasses of any fluid a day. I don't drink sugary beverages. I do drink one cup of half coffee half milk. But I find any short term or continued substantial fluid intake makes me feel unwell throughout the course of the day. (I periodically go on water-conscious healthy binges where I try to get at least 4-5 cups of water/day in me, but it never lasts more than a few weeks to a month because of the nausea/headache/lethargy/general malaise that seems to accompany it.) I will try the addition of 1 Tsp salt and 1 Tsp sugar to see if that helps. Here's to hoping!
