LOW systolic, normal diastolic... how can that be?

Hi everyone! I really need to know at what level the systolic is TOO low. Lately, I have had what seem like really low systolic readings. Like 95/80...93/78...91/82.

I take the readings at least 5-10 minutes apart. Then after about an hour or so, the systolic goes normal, around 120/80.

Also, I sometimes have spikes just in the diastolic number. Like 121/90...124/94...117/96. These spikes don't last long.

All these BP readings are 'resting' rates, and seem to have no pattern. My doc thinks I may have a thyroid issue (test showed mild FTI elevation), and is referring me to an endocrinologist to find out for sure. My doc already knows about the spikes, but the systolic drops are something new. For some reason I have always thought the diastolic number was the 'important one' (until now).

Systolic drops and diastolic spikes... though never at the same time. I'm clueless. I know thyroid problems can cause some strange symptoms. I guess what I really wanted to know is what point is systolic TOO low?

Any input anyone can give will be VERY appreciated!

For one, you shouldn't be taking readings 5-10mins apart. It is not a wise thing to do and the readings are probably not accurate because of this. Doctor's recommend taking BP readings only once a day, always at different time of each day to get an idea of what it does at different times of day. Really, you shouldn't be taking it so much. Anyway, yeah, that number is getting a bit low, not life threatening but low none the less. I'd see your doctor abut the spikes, that seems odd although I have no idea what may cause it.
Good luck with it

Those are strange numbers, but you shouldn't be that obsessed with them. Have a thorough check up and then forget about it for a while.
