Where does your BP baseline (outside of pregnancy and postpartum) fall?
While most obstetric guidelines don't include ranges for what is considered "low," we do see nutritional deficiencies when people fall below optimal guidelines.
What's optimal?
Systolic BP (that's the top number)
Above 100
AND
Diastolic BP (the bottom number)
Below 80
When the systolic (top) OR the diastolic (bottom) falls below, or rises above, this optimal range, you're in a state of imbalance.
I really want you to pay attention to these ACOG guidelines for Elevated, S1, and S1 hypertension... many practitioners, midwives included, routinely tell women that their 124/82 BP is "totally normal."
No... no it is not.
There is likely some form of dehydration, nutritional deficiency, or stress (mental or physical) happening and this is an opportunity to dig a little deeper BEFORE we get into the danger ranges.
Another consideration is the classic line of, "oh, well, your BP is suppose to rise at the end of pregnancy."
Ummm... no...
With a healthy mother that doesn't have any imbalance symptoms, her BP will generally drop as her blood volume expands, reaching its lowest point around the beginning of the third trimester. IF this happens, THEN the blood pressure will begin to increase only reaching back to baseline (pre-conception) levels and NOT rising higher than the optimal range OR above her pre-conception baseline.
Yes, there are normal fluctuations that happen with activity throughout the day, but these are not drastic, and still should remain within optimal levels.
