30 weeks of pregnancy is high blood pressure serious?

If the blood pressure of the patient is only slightly elevated and can

be treated in a timely manner, the blood pressure can usually be

controlled at a normal level, generally not serious. However, if the patient's blood pressure has been significantly elevated, or even preeclampsia or eclampsia has occurred, and failure to treat in time, it will cause complications such as HELLP syndrome, premature delivery, placental abruption, etc., which are generally more serious.

Patients should limit sodium intake daily to prevent water and sodium retention, which will cause blood pressure to rise further.
