I was talking to KellyFlyWithHope on facebook the other day, and we both had a similar experience, so I wanted to ask around...
Do you find your blood pressure is abnormally low if you have it taken when the barometric pressure is low?
I had it taken at Dr Youngs once and it was like 98/54, but I had consumed a ton of caffiene that day (I'm caffiene free 90% of the time). I also was in the early stages of a migraine and hadn't taken a triptan yet. My conclusion was that it was because the barometric pressure was low that day (hence the migraine).
Kelly had a similar experience with low BP/low barometric pressure.
That got me thinking.... Does the low pressure over dilate my blood vessels, causing the low blood pressure? And if that is what is causing the low blood pressure, is the over dilation of my vessels triggering the migraine?
So, I'd like to know if anyone else has had similar experiences.
I just had mine taken at the neuro and it was 100/70, according to the weatehr channel it's Barometer:30.11 in and rising. I would think the Inderal would have worn off by now, I stopped it about a week ago. I'm usually @110-115/65-75.
Interesting theory. I check my BP occasionally when I have a migraine because it ususally increases with pain. I don't know the pathophysiology but I am not sure that blood vessels always are dialated with low blood pressure. Such as with tachycardia, heart beating too fast, blood pressure can be low. And when you stand up and blood pressure drops the body responds by increasing the heart rate and narrowing the vessels. Would be a good question for a MD or Ask the Clinician?
But someone remind me. I remember the vascular component of a migraine includes constriction and then dialation of the vessels?
Interesting, I'll have to keep track of this. Right now my resting heart rate is 52bpm (can't take bp right now) and the current barometric pressure is 29.84 and falling.
After a spell of blacking out when my migraines started coming on full blast, we were finally able to get my BP and found it to be 72/40, which casued the blackout and they are ASSUMING may be causing the migraines.
I've been on BP meds for the past 2 months to raise my pressure....no more blackout spells, but the migraines haven't stopped...
My BP's been low all my life, generally around 90/60. I've even been rejected as a blood donor for my low BP.
I think there's more to storms triggering migraines than just low barometric pressures. How many of us have ridden express elevators to the tops of very tall buildings without getting hit? That's a serious drop in atmospheric pressure!

Nope. Mine's on the low side, but it's pretty consistent. I've never noticed any shift down further yet due to barometric pressure.
Actually, caffeine usually has the opposite effect, temporarily increasing blood pressure.
I meant that it was weird that my BP would be so low having had so much caffiene b/c I know it usually raises it.... I just wanted to clarify that so you don't think I'm that much of a ditz
No worries. I don't think you're a ditz in the least.
I don't know about my blood pressure, but whenever the barametic pressure falls, I get a migraine. I can always count on it. My BP is usually low anyway. If it goes much lower, I would be really concerned. I will watch it next time that the barametric pressure falls and I get a migraine. This just happened AGAIN a few days ago. UGGHHH!
I am glad to see that there are others making the connection between migraines and barometric pressure and low blood pressure. I was wondering if there was a connection myself.

Hello and welcome to our forum family! Our goal is to provide everyone with the information and support that we all need to manage our Migraines and/or headaches. To that end, we consider this a “safe harbor,” where nobody tries to sell us anything, and we all use “family-friendly” language so parents are comfortable letting their children read the forum with them.
Please take a few minutes to review our policies and guidelines along with the other information in the START HERE folder. For information about Migraines, a good article to begin with is Learning About Migraines - Where to Start.
Not only do barometric weather changes play a role in triggering a Migraine for some people, see Migraines Often Triggered By Change In the Weatherbut air pollution may too. See Impact of Air Pollution on Migraines and Headaches for more information.
We look forward to hearing more from you.
