Yes I have passed out when the dehydration/urination is excessive. I weigh quite a bit less when that happens and appear very pale, cold and with collapsed veins. When I am able to rehydrate, within about an hour my color returns, veins fill out, and I feel warm again, blood pressure and pulse go back to near normal.
It does seem lately that drinking juice for the potassium actually aggravates the excessive urination. Could this be from rapid increases in glucose concentration because of the dehydration, similar to what occurs with dehydrated diabetics that causes excessive urination?
I am not diabetic but I am prone to wide glucose fluctuations. In the past I have seen it over 200 and as low as the 30's several times. Usually it is between 60-110 though and never above 100 fasting.
I do think I am starting to see a pattern emerging. The symptoms do seem to always get worse when I am taking higher amounts of sodium but without increase in water. When I eat higher sodium foods my heart starts beating slower (<60, sometimes <50) and weaker, my blood pressure increases, I feel weaker, more short of breath and dizzy. I also feel worsened muscle cramps, sore muscles/neck/back, muscle spasms and twitching. I also have nausea, reduced appetite, and have continued losing weight unintentionally.
Could a lot of these symptoms, and especially this unusual reaction to sodium, be due to potassium deficiency?
Potassium is the only thing I have not been getting large amounts of because most of the foods high in potassium are too high in sugar or carbohydrates which seem to worsen the urination. I had also been on a low carbohydrate, high protein, high sodium diet during the 2 months prior to when these symptoms began.
The potassium I gave above was from 4 weeks ago and the symptoms are much worse now than at that time. It had been below 3 when I was in the hospital, and was given potassium, so I am certainly am prone to hypokalemia.
