Hi folks , had my routine kidney check today and was told my levels all stable apart from my potassium level which is 5.8 . She asked if i had over indulged on Christmas cake and chocolate over the new year . I have had some but don't think I over indulged , anyway that's what she is putting it down to she said . I said well will you take my bloods today to check again which she has . When I have read about high potassium levels when I got home I have discovered that 5.8 is actually very high , 6 is a dangerous level so I am surprised she just put it down to chocolate and left it at that . I have read what foods contain high potassium , milk and salmon are among them which I am suppose to have because of osteoporosis , no mention of chocolate . Another thing I read was that certain drugs can cause it like ibersartan which I have been on for about 9 months , she didn't mention that . Has anyone else with lupus nephritis had this problem , I read this can cause kidney failure .
