My son passed several kidney stones last week, he is 30 yrs old, a type one diabetic, but in generally good health. Last night he vomited and had diarrhea and had to go to e.r. because he was dehydrated. They did blood work, i.v. and sent him home after telling him his potassium level was high. Could the kidney stones have caused this? He had been in the same e.r. the week before because of stones, they did blood work then and said nothing about elevated potassium levels.
