voiceover okay, so i want to start off with a scale. So this is a scale, a time scale. And on this end is before pregnancy, and on this end is after pregnancy, and then in the middle is the 20week point of pregnancy. And I want to use this scale to show you how different.
Pregnancy related hypertensive disorders are split, because they’re split up according to when the hypertension occurs and also according to how severe it is. So starting on this end, let’s say a woman has had high blood pressure for several years.
Before she became pregnant, or if she’s found out to have high blood pressure before 20 weeks into her pregnancy, then we say that she has chronic, she has chronic or preexisting, chronic or preexisting hypertension.
So, her hypertension has nothing to do with pregnancy, because she either had it before she became pregnant, or before the 20week point into her pregnancy. And this 20week point is important because before it, sort of in the early stages of pregnancy, pregnancy reduces blood pressure.
So if a woman is hypertensive before the 20week point, then the cause of her hypertension has nothing to do with the pregnancy. Now, if instead she’s found to have high blood pressure after the 20week point in her pregnancy, we say that she has gestational,.
She has gestational hypertension. I’m just gonna abbreviate hypertension as HTN throughout this tutorial, I’ll save a lot of time. Or, hypertension related to her pregnancy, that’s what gestational hypertension is. And typically, gestational hypertension, usually,.
Should resolve within 12 weeks of giving birth. If it doesn’t, then chances are that the woman probably had high blood pressure before ever becoming pregnant, but that we didn’t find it in the earlier stages of pregnancy because of that physiologic lowering of blood pressure.
That we were talking about that occurs early on in pregnancy. So, I guess you can say that these two conditions, chronic hypertension and gestational hypertension, are sort of the milder forms of hypertension. So now let’s talk about the more serious.
