High blood pressure in pregnant women belongs to gestational hypertension, and the treatment includes non-pharmacological treatment, oral drug treatment, intravenous or intramuscular drug treatment. 1. Non-pharmacological treatment: suitable for all patients with hypertensive disorders in pregnancy, mainly including strengthening blood pressure monitoring and limiting physical activities, severe patients may need bed rest and moderate dietary salt restriction. 2. Oral medication: Oral methyldopa, labetalol and nifedipine are preferred for severe hypertension (systolic blood pressure ≥160mmHg and/or diastolic blood pressure ≥110mmHg), which reduces the risk of cerebral infarction and complications in the mother. 3. Intravenous or intramuscular drug therapy: injections of labetalol, nicardipine, and uradil, intravenously or intramuscularly, are recommended for severe hypertension. The use of antihypertensive drugs for hypertension in pregnancy may present risks such as inhibition of intrauterine growth of the fetus, so it is recommended that the patient go to the hospital for consultation and standardized treatment under the guidance of the doctor.
