Is high blood pressure during pregnancy dangerous?

Nowadays, more and more people are troubled by high blood pressure, especially the middle-aged and elderly, who are at high risk of high blood pressure. Of course, for pregnant women, once the blood pressure is too high, they also need to be vigilant. After all, this is a sensitive time, which may affect the health and safety of the fetus at any time, so they should not be careless. So, is the harm of high blood pressure during pregnancy serious?

Pregnancy-induced hypertension is very harmful and can cause multiple organ damage such as convulsions, coma, heart failure, and in severe cases even threaten the lives of mother and child, and may also cause sequelae. The most common is placental harm. Pregnancy-induced hypertension can cause uterine vasospasm, vascular wall necrosis, and lumen stenosis, affecting the supply of maternal blood to the fetus, damaging placental function, and leading to intrauterine growth retardation of the fetus. In severe cases, placental abruption occurs, leading to stillbirth, stillbirth, or neonatal death.

The harm to the brain cannot be ignored. Pregnancy-induced hypertension can cause spasm of small arteries in the brain, causing ischemia, hypoxia, and edema of brain tissue, loss of self-regulation function of cerebral blood vessels, causing punctate or localized macular hemorrhages. Patients experience headaches, dizziness, nausea, vomiting, convulsions, and may even cause coma.

Heart damage is also very common. Pregnancy-induced hypertension can cause coronary artery spasm, leading to myocardial ischemia, interstitial edema, punctate hemorrhage and necrosis, increased cardiac burden, and in severe cases can lead to heart failure. The harm to the kidneys is very serious. Pregnancy-induced hypertension can cause sclerosis of renal arterioles, stenosis of the tubular lumen, blood flow blockage, renal ischemia, and thus renal function damage, which can cause oliguria and proteinuria, and in severe cases, renal failure may occur.

The harm to the eyes is obvious. Pregnancy-induced hypertension can cause spasm and ischemia of the retinal arterioles in the fundus. In severe cases, retinal edema, retinal detachment, or cotton-like exudate or bleeding may occur. Patients may experience dizziness and blurred vision, and in severe cases, temporary blindness may occur. There is also harm to the liver. When pregnancy-induced hypertension is severe, it can cause spasm of the small arteries in the liver and then dilation and relaxation. The blood vessels suddenly become congested and the pressure rises suddenly. Localized bleeding occurs around the portal vein of the liver, and liver cells suffer varying degrees of necrosis due to ischemia and hypoxia.

As for whether high blood pressure during pregnancy is harmful, everyone is also very clear. Pregnant women not only need to avoid high blood pressure, but also need to prevent high blood sugar. In short, gestational hypertension and even diabetes are not allowed. You must pay attention to a reasonable diet, get more rest, exercise properly, and it is important to regulate your own health.
