Low Blood Pressure in Third Trimester?

Hello Everyone!  Well I'm 31wks w/baby #6. I've normal BP's from the beginning of Pregnancy. However, starting at about 29wk I started getting Short of Breath and Dizzy. I'm long in the waist and baby is low. No pressure on Lungs or Dia. I drink over 64oz of water a day + other liquids...I've tried Sugar & Salt..Lying of left side...and just sitting down..Nothing helps....It always comes and goes....I could be sitting, ironing, or just walking down the hall and I'll get so SOB and have such hard heart palipations that I have to sit where I once stood before I fall over or pass out. During my last episode my BP was 79/54 with a Pulse of 101 yet sitting here right know my BP is 92/55 with a Pulse of 106....Has anyone had a similar experience? Any tips? Is baby really getting enough blood/oxygen?

I was alittle curious too as to why my blood pressure readings have been lower than my norm.  I read that in the third trimester, your baby starts pressing on a vein.  This causes your feet to swell and causes lower blood pressure readings.  If you doctor is fine with your readings, I wouldn't worry.

It's most likely just your body's unique reaction to pregnancy but it's definitely worth talking to your doctor about....I have REALLY low blood pressure too, but I take a beta-blocker for a heart condition. Usually my BP is so low that it takes 4 or 5 times before they can even get a reading, lol...at one point it was like 67/90. Sometimes if you're dehydrated your blood pressure drops, because it's related to blood volume...so try drinking a LOT of fluids and take the measurement again. dehydration can also cause heart palpitations and dizziness. I also want to say that my pulse averages at about 100-110....before I started taking the beta-blocker it was about 130+ though (resting) because of my valve condition (which was exacerbated by pregnancy...my heart condition (barely noticeable before) definitely got worse after I was pregnant with my daughter...so you may have an undiagnosed valve condition which is easy to treat but does require attention). You may want to have them check your heart by ECG and make sure that the extra strain from pregnancy isn't affecting it...but try the fluids first.

The low BP's started in between my Appt's. I go in next Monday.. I've been charting my BP's and Pulse for him to see. The really low BP's happen every time I have SOB, Dizziness and Heart Palipations.. Which could be 10-20 times a day.....What worries me is the frequency of all the things combined...

Your current BP is 92/55 which is very close to mine 100/60 yesterday and the doctor was very happy with that. My pulse is probably 90-100.   Th 79/54 is pretty low though, does that happen often? if your BP is usually arount 92/55 I wouldnt worry too much. Does the doc check your BP every appointment? Do they seem concerned?
