Blood pressure (BP) refers to the lateral pressure that acts on the vascular wall per unit area when blood flows in the blood vessel, and it is the driving force for the blood to flow in the blood vessel. In different blood vessels, they are called arterial blood pressure, capillary blood pressure and venous blood pressure. Generally speaking, blood pressure refers to the arterial blood pressure of systemic circulation.

Systolic blood pressure: 90-140mmHg; Diastolic blood pressure: 60-90mmHg.

Pregnant women whose blood pressure is higher than 140mmHg and (or) 90mmHg may be hypertension or borderline hypertension. Pay attention to the occurrence of pregnancy-induced hypertension; if the blood pressure is lower than 90mmHg and (or) 60mmHg, it may be hypotension. Pay attention to strengthening nutrition.

1. Mild pregnancy-induced hypertension. Generally, no medication is needed, and attention should be paid to:

(1) Rest: appropriately reduce work and ensure adequate sleep.

(2) Left decubitus position: Take the left decubitus position when resting and sleeping. The left decubitus position can reduce the pressure of the right-handed uterus on the abdominal aorta and inferior vena cava, increase the return heart blood volume, improve renal blood flow, increase urine output, and help maintain normal uterine placental blood circulation.

(3) Diet: You should take in enough protein and vitamins to supplement iron and calcium. Salt does not need to be strictly restricted. Long-term low-salt diet can cause hyponatremia and prone to blood circulation failure after delivery. In addition, low-salt diet affects appetite and reduces protein intake, which is detrimental to mothers and children. People with edema should limit salt.

2. Moderate and severe pregnancy-induced hypertension. Once diagnosed, they should be hospitalized and treated actively to prevent eclampsia and complications. The treatment principles are antispasmodic, lowering blood pressure, sedation, reasonable volume expansion and diuresis if necessary, and termination of pregnancy in a timely manner.

1. Appropriate consumption of salt can increase blood pressure and improve symptoms such as dizziness, drowsiness and weakness. But the salt intake should not be too high; at the same time, drink more water, more water can increase blood volume after entering the blood, which can increase blood pressure.

2. Increase dietary nutrition, eat more foods that warm the spleen and kidney; eat more easily digestible protein foods, such as chicken, eggs, fish, cheese, milk, etc., eat less and more meals. Eat lotus seeds, longan, jujube, mulberry and other fruits. These foods have the power of nourishing the heart and blood, strengthening the spleen and brain.

3. Eating ginger often can promote digestion, invigorate the stomach, and raise blood pressure. You can sprinkle ginger in vegetable soup or use ginger to soak in water instead of tea. Eat less winter melon, watermelon, celery, hawthorn, bitter gourd, mung bean, garlic, kelp, onion, sunflower seeds and other foods that have a blood pressure effect.

4. Choose an appropriate high-sodium, high-cholesterol diet. Daily intake of table salt is 12-15 grams. Foods such as brain, liver, eggs, butter, fish eggs, pork bones, etc. that contain more cholesterol can increase blood pressure if eaten in moderation.

Pregnant women need to measure their blood pressure during each pregnancy check. When the blood pressure readings show abnormalities, and they are abnormal several times in a row, it is a cause for concern. If the blood pressure is higher than 140/90 mmHg twice in a week, and the blood pressure is normal, the doctor will judge whether preeclampsia occurs based on the blood pressure measurement results.
