Hypertension present before pregnancy (or up to 20 weeks of pregnancy) is now classified as &#8220;pregnancy complicated by hypertension,&#8221; hypertension alone occurring by the 20th week of pregnancy is classified as &#8220;gestational hypertension syndrome,&#8221; and hypertension and proteinuria are classified as &#8220;preeclampsia.&#8221;<\/p>\n\n\n\n<p>Since 2018, even if there is no proteinuria, conditions such as liver or kidney dysfunction, neurological disorders, blood coagulation disorders, placental insufficiency, and fetal growth restriction are also classified as preeclampsia.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"c1-2\"><span class=\"ez-toc-section\" id=\"%E2%80%9CSwelling%E2%80%9D_is_not_a_symptom_of_pregnancy-induced_hypertension\"><\/span><strong>&#8220;Swelling&#8221; is not a symptom of pregnancy-induced hypertension<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Before pregnancy-induced hypertension, when pregnancy was called toxemia, one of the three major symptoms was &#8220;swelling (edema).&#8221; However, swelling is a symptom that is seen in more than 30% of pregnant women.
