A heterotopic pregnancy is a complication of pregnancy in which both extrauterine pregnancy and intrauterine pregnancy occur simultaneously. [2] It may also be referred to as a combined ectopic pregnancy, multiple‑sited pregnancy, or coincident pregnancy. The most common site of the extrauterine pregnancy is the fallopian tube.
Similarly, many of the risk factors are the same, except that not having been pregnant previously does not seem to be a risk factor for postpartum preeclampsia. [102] There are other risk factors related to the labor and/or delivery that are associated with postpartum preeclampsia like cesarean delivery and higher rates of intravenous fluids. [101]
The greatest risk factors are an abnormal position of the baby within the uterus and a premature or small baby. [2] Other risk factors include a multiple pregnancy, more than one previous delivery, and too much amniotic fluid. [2] [3] Whether medical rupture of the amniotic sac is a risk is controversial.
Pregnancy itself is a factor of hypercoagulability (pregnancy-induced hypercoagulability), as a physiologically adaptive mechanism to prevent postpartum bleeding. [165] However, in combination with an underlying hypercoagulable state, the risk of thrombosis or embolism may become substantial. [165]
Often gets better but may last entire pregnancy [2] Causes: Unknown. [3] New research (late 2023) indicates an elevated level of one specific hormone. Risk factors: First pregnancy, multiple pregnancy, obesity, prior or family history of hyperemesis gravidarum, trophoblastic disorder: Diagnostic method: Based on symptoms [3] Differential diagnosis
Several contributors may result in placental abruption. This includes: pre-existing maternal factors (e.g., smoking, hypertension, advanced age), [51] as well as pregnancy-related factors such as multiple pregnancies or the presence of in-utero infections. Identifying risk factors beforehand in order to take steps and make quick reactions to ...
A multiple pregnancy may be the result of the fertilization of a single egg that then splits to create identical fetuses, or it may be the result of the fertilization of multiple eggs that create fraternal ("non-identical") fetuses, or it may be a combination of these factors. A multiple pregnancy from a single zygote is called monozygotic ...
There is a small amount of evidence that rutosides (a herbal remedy) may relieve symptoms of varicose veins in late pregnancy but it is not yet known if rutosides are safe to take in pregnancy. [25] Risk factors include obesity, lengthy standing or sitting, constrictive clothing and constipation and bearing down with bowel movements. [citation ...
