If a patient develops hypertension during pregnancy, blood pressure can be brought down by the following means: 1, oral medication: patients are advised to take oral nifedipine extended-release tablets or labetalol-type antihypertensive drugs, or they can take methyldopa, but the more preferable are nifedipine extended-release tablets and labetalol; 2, control diet: in addition to controlling blood pressure with medication, it is also necessary to combine lifestyle interventions and improvements. For example, we should pay attention to low-salt and low-fat diet, control the rate of weight gain, and eat more fresh fruits and vegetables to help further stabilize blood pressure; 3, timely monitoring of blood pressure: the process of lowering blood pressure is not recommended for patients with hypertension during pregnancy, generally not less than 130/80 mmHg, because if it is too low, the perfusion of the uteroplacental blood flow cannot be guaranteed. Patients should pay attention to monitoring blood pressure and keep their mood happy to help better manage blood pressure.
