question: My father is ill. He was very dizzy and disorientated in church yesterday. He had to walk out 1/2 way thru because otherwise he would of fallen over. Mom took him to the Emergency Room and they told him all checked out ok just that his potassium level is slightly low at 3.5 and the doctor added onto his regime an additional two tabs of potassium supplements for two more weeks and then get tested again. He sent him home. Today, my brother tells me that dad is having slurred speech at times.. Whats up??
