Pregnancy induced hypertension, specifically pregnancy induced hypertension syndrome. This symptom usually occurs in pregnant friends. This symptom can also have extremely adverse effects on pregnant friends. So, how is preeclampsia caused? Next, the editor will provide a detailed introduction to this aspect, hoping to be helpful to everyone.
1. Immunity and genetics. Pregnancy induced hypertension in multiparous women is relatively rare in clinical practice. Women with preeclampsia are more likely to suffer from preeclampsia. Some people believe that it is related to maternal recessive genes or recessive immune response genes.
2. Prostaglandin deficiency. Prostaglandins can dilate blood vessels, and generally maintain a balance between vasopressors and antihypertensive substances in the body, keeping blood pressure at a certain level. Prostaglandins, a vasodilator, are reduced, and the responsiveness of blood vessel walls to vasopressors increases, resulting in an increase in blood pressure.
3. Uterine and placental ischemia. Multiple pregnancies, polyhydramnios, primiparous women, excessive uterine enlargement, abdominal wall tension, etc. can all increase uterine pressure, reduce or slow down uterine placental blood flow, cause ischemia and hypoxia, vascular spasm, and increase blood pressure. Some people also believe that after ischemia and hypoxia of the placenta or decidua tissue, a pressor substance can be produced, causing vasospasm and raising blood pressure. In addition, its occurrence is closely related to climate change, and its incidence rate is the highest in winter, spring, autumn and winter; Pregnant women with short stature, anemia, malnutrition, work stress or family history of hypertension have a higher incidence rate of pregnancy induced hypertension.
The above is some content introduced by the editor about how preeclampsia is caused, hoping to be helpful to everyone. The editor believes that congenital causes are unavoidable, while acquired causes can be controlled and treated. The editor suggests that pregnant women should develop good and healthy habits and adjust their sleep schedule.
