Suffice it to say the link does have a list of drugs that cause
hyponatremia.

In the olden times...there were fewer drugs, and the only people affected much by hyponatremia, were the elderly and those
who had certain kidney problems. Therefore kidney doctors are best trained to handle this.

But as time passed, drugs came along to share hyponatremia with younger people. So the non-kidney doctors have less understanding of this.

You can see by the link it is not an easy thing to identify or treat.
And the types listed depend on what is causing it.

One rare mental illness causes it, called dipsomania. This is where a mental patient over drinks water, as part of their mental condition...too much water you know can kill you...most of us have heard that... and this is how it happens=hyponatremia. When sodium gets too low, or diluted out by too much water, the nervous system cannot work. Sodium and potassium (and calcium to a lesser extent), are how the nerve electrical potentials are created and messages sent. Too much or too little of any of them result in brain failure, muscle cramping or no muscle relaxation (magnesium is the relaxer and calcium the contracter). All 4 minerals are called electrolytes and that is why they are measured in blood tests.
Calcium and magnesium also work in other places than the nerves, but sodium and potassium are how nerve impulses get sent. They move in and out of the nerve membranes to generate electrical signals.

I had an internist once tell me than only the "smartest" doctors become kidney specialists. This is because the chemistry of our bodies is what the kidneys manage, and the chemistry is tough to understand, and highly inter-related to everything else.

So you need to know this is important, and actually critical.
You need to know that Tegretol can create an imbalance in your body that requires emergency treatment. And that if you need to change it now, it needs to be tapered off carefully. That is what you need to understand at this time.;)

Well gee, Mrs. D... guess what happened. I was at work and drinking lots of THIER water in my wieght loss quest, plus the accupuncurist told me I needed more water. At some point in the day - all of a sudden, I began dying of thirst, drinking water made no difference because the water as it was hitting my throat did nothing to stop the all of a sudden dying of thirst in the Sahara Desert - overwhelming feeling. I went into a complete panic called my boss and told her I needed to go to the ER. Then I realized, I was in some kind of horrible panic and couldn't drive - I had to call an ambulance. Once I got to the hospital the panic subsided and I was ok - then they gave me the IV's. Full of IV, I get up next morning feeling like a million bucks. Go to work. Drink Gatorade most of the day, run out of that, start drinking the office water. Late afternoon, it all happens again, only the second time I could sustain the panic well enough to drive myself to the ER.

I realize you have found a link with tegretal but let me go on.. I am astonished by what you come up with btw.... (dont forget there was a week and a half of loose stool going on here too)

I am disabled bp but still work part time. All week long goes by and nada. Next weekend, I am back at work. I had brought in some of my own water. Still trying to drink lots of water as I had been told. When mine ran out, I started on the office water again. All of a sudden... here it comes - the thirsty feeling, the panic - I thought wait - I was fine all day... and realized - until I started on the office water... So I ran to a co workers off and took one of her bottled waters. Began drinking that... it immediately began easing up. It eased up a lot. It was still all I could do to stay at work the last 45 minutes of that day because "it" had started again.

THE NEXT DAY - back to work - brought all my own water - even my own coffee so would not have so much as one drop of the office water (which I"m sure is City Water, btw- but this building is old and these people are cheap and maintenance is lacking)... Guess What - NOT ONE HINT OF THE PROBLEM. Not even an inkling. Not even the faintest twinge - as if it had never happened.

I will never drink this office water again. And there's probably nothing wrong with it - except for some little thing that is significant only to me.

The dying of thirst drinking thing has never returned since, it's been four weeks I guess. My sodium levels rose back up to the minimum required ten days later. My primary physician after hearing the story said - drink when you need to- but don't OVER drink. (I was over drinking on purpose at the advise of that accupuncturist, mostly)

Honestly, I shudder to think what I would do without my tegretal. It stops the all over itching, it's the only weapon I have, it eases the leg cramps when they are bad. I just dont know what I'd do without it - but isn't it interesting what you said and the parallel in my story.
