Hydrochlorothiazide
"I am a 57 year young woman in relatively good health. I struggled with my weight since my early 30's add anxiety & I developed high blood pressure (BP) by age 40. I have been on 50 mg. of Losartan & 12.5 mg. of hydrochlorathiazide. My BP did not improve much & averaged 150's over 80's to mid 90's. Recently I started on a ketogenic diet which works great for insulin resistant folks & I have lost 30 lbs in 10 weeks & brought my BP down to 116/70 I asked my Dr to adjust my meds she said it's too soon. I began to have severe dehydration, black outs & dizziness upon standing, profuse sweating, heat intolerance  & fatigue so I stopped the hydrochlorathiazide on my own and all the bad symptoms went away & BP still great! Listen to your body!"
