I bought a manual machine and it comes back to 130-140, perhaps it was just the machine in my GP office. She used the right cuff on me and she tested it on herself too and got 120. It was a brand popular in Europe, veroval duo or something like that. On a more shitty machine without changing cuff I got 150 too... I don't know. My blood potassium level and sodium are perfect. I'm kind of at a loss on why the bp reading is so high. I walk every day 3-4 km with heavy backpack, I don't do hard cardio tho and I drink quite a lot of liquids, one guy told me I drink too much. 3 liters of milk and water I don't count but more then 2 liters probably
