I'm an intermediate level competitive weightlifter, first diagnosed with hypertension a few years ago in an anatomy lab. I thought it was a mistake. Turns out for a few years I've had high blood pressure of 140-150/90. I'm 24 now. Symptoms probably began when I was 22 or so.
My dad's side of the family have all dealt with it. My dad keeps his blood pressure in normal ranges by eating a low sodium diet.
I'm 5'8" tall and 165 lbs, so BMI would tell you I should lose weight, but my body fat is in the 10-12% range. I eat very well - lots of fruits and vegetables, no salt on anything, little processed food, take my vitamins and omega 3s.
Lab results showed high creatinine and hypokalemia (3.2mEq). My cardiologist told me to go easy on the post workout protein shakes and come back in after a month. I did - the creatinine level dropped, hypokalemia and hypertension didn't improve.
Despite how careful I am about my diet, I think I could use more potassium. I spot checked my diet in Fitday and on that particular day, potassium was the only micronutrient I was low on. I'm hesitant to supplement though because of how serious hyperkalemia can be.
What do I do? My doctor's recommendations seemed pretty clueless. He didn't catch that the high creatinine correlates with being male and muscular and didn't touch on the issue of mild hypokalemia at all. Is there a way for me to supplement potassium in a controlled fashion and stop it if I appear at risk for hyperkalemia?
