I have general dysautonomia, diabetes insipidus (fluid wasting not blood sugar) and a small pituitary tumour. I've been relatively stable using IV Saline at home, scheduled desmopressin, and as needed I take mitodrine. Unfortunately, I'm struggling a bit keeping my blood pressure up. This weeks readings look something like 84/75, 83/68 etc... More irregular heart beats and chest pain than normal, and so tired with blurred vision. I guess I'm just wondering, how low is to low? My hunch is to just wait and see. My Doc. is amazing really, but don't know that he's actually going to be able to suggest good ideas for increasing pressure. I have a cardiac cocktail from my naturopath that usually helps with the irregular heart rhythm stuff, but it has niacin and am nervous to take it lest it tank my pressure more. I've also been having some trouble with my sodium balance so I'm nervous about IV fluids.. Feel a bit stuck. Ideas? My gut says to ride the wave and wait, but how low for how long is too low, and is there anything else I can/should be doing? FYI: I have had my blood pressure dip very low (like as in 70 systolically), and been hospitalised with a "TIA" that resulted in 8 months of right sided weakness, so this doesn't help with my nervousness about it - not to mention trying to manage 2 little kids (I want them to have a kind, engaged mommy, not one who lays on the couch, who can't see straight :-(. Any ideas? Advice?
