Toxemia of late pregnancy

Japanese: 妊娠中毒 - にんしんちゅうどく（英語表記）toxemia of late pregnancy

Medically, it is called toxemia of pregnancy. It is a pregnancy-related disease that is often seen in the latter half of pregnancy (especially after the 20th week of pregnancy), and its exact cause remains unknown to this day. Although the lesions affect multiple organs, the condition often heals or improves quickly once the pregnancy ends. The three main symptoms of toxemia of pregnancy are edema, high blood pressure, and proteinuria, but eclampsia (sudden convulsive attacks that occur during pregnancy, childbirth, and the puerperium), which is characterized by severe neurological symptoms, is also included as a special type of the disease. Advances in diagnostic methods have led to the exclusion of various incidental pregnancy complications (pregnancies complicated by heart disease and diabetes) that were previously included in toxemia of pregnancy, and improvements in the management of pregnant women, so the incidence rate has now fallen to around 8-12% of total births (previously 10-30%).

医学的には妊娠中毒症という。妊娠後半期(ことに妊娠20週以降)によくみられる妊娠に起因する疾患で，その本態は今日もなお不明である。病変は複数の臓器に及ぶが，妊娠の終了により速やかに治癒あるいは軽快することが多い。浮腫，高血圧，タンパク尿が妊娠中毒症の三大症状であるが，神経症状の著しい子癇(妊娠，分娩，産褥（さんじよく）期に突発する痙攣（けいれん）発作)も特殊型として本症に含まれる。　診断法の進歩により，従来妊娠中毒症のなかに含まれていた各種の妊娠偶発合併症(心疾患や糖尿病合併妊娠)が除外されたり，妊産婦の管理が改善されたために，現在では総分娩数の8～12％前後(以前は10～30％)に発症率は低下している。
