Hi for the third time since my twenties my blood pressure has become very high for no apparent reason.(227/127) even though I was on medication. I have had a series of tests to check no organ damage occurred so far so good. I still have to do a 24 hour urine test to check the function of my adrenal glands Ithink. None of the doctors seem concerned about my history of hypothyroidism and vitamin d deficiency. The vitamin levels are Ok at the moment but my TSH is at 1.5 down from 3.5 when My vitamin d levels were very low. Gp thinks TSH is ok but before the problem with the vitamin d it had been steady at around 0.5 with T3 and T4 in range. ( I take levothyroxine and liothyonine)I feel OK so I'm not going to make a fuss unless this may be tied in with sudden increases in blood pressure. Has anyone come across this?
