<s>[INST] Hello my name is Bob. A couple of days ago I had blood work done to check again my high potassium level. My previous blood draw was because I was concerned about urinating so often in a day. The potassium level was high and a week later still high. I had been taking Lisinopril so my doctor said to discontinue for three weeks then have another blood draw. My question is I have noticed today (more so today) and yesterday dizziness. Is this an effect from high potassium levels? Should this be a concern? I have been dehydrated from not drinking enough water which I am working at trying to take in more. [/INST] Hi, dear. I have gone through your question. I can understand your concern.  But if you feel dizziness then you should consult your doctor urgently.  Because you have history of high potassium, and it is very sensitive.  Hyper or hypokalemia can lead ti life-threatening complications or arrhythmia. So consult your doctor and check your potassium level and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
