I am pregnant with high blood pressure 144/91 how to treat ah does not affect the baby

Normal human blood pressure value is within 140/90mmhg. At present, the patient's blood pressure is a little high, so weight control is needed to control diet. Usually, diet should be low salt and low fat. High blood pressure in pregnant women will lead to hypertension during pregnancy, and serious cases will cause maternal edema, renal failure, fetal growth restriction, placental abruption, etc.
