When Ms. Xing, a 39-year-old mother of two, had her blood pressure measured, the result showed 170/110 mm Hg. In the subsequent examination, the laboratory test showed: urine protein ++++, which should be negative for normal; high urine protein can affect kidney function. ultrasound results showed: reverse diastolic blood flow in the umbilical artery, indicating that the fetus has shown symptoms of hypoxia. Ms. Xing could be diagnosed with gestational hypertension, which made it hard for the doctor not to be anxious for her. Advanced maternal age is often prone to gestational hypertension, so what are the ways to prevent gestational hypertension? 1, regular prenatal checkups This is the best way to detect hypertension early. At each checkup, the doctor will measure blood pressure, urine test and weight, and check for leg edema. These are important indicators to identify hyperemesis, and if there is any abnormality, the doctor will find it immediately and take early symptomatic treatment so that the condition can be controlled and will not develop seriously. 2.Reasonable arrangement of pregnancy diet Hyperemesis is closely related to nutritional factors. Too much intake of animal fat and calories, and not enough intake of protein, various vitamins, inorganic salts and trace elements can trigger or aggravate hyperemesis. Therefore, it is crucial to guide pregnant mothers to arrange their diet properly to prevent and control the development of hyperemesis. 3, regular life and strengthen self-care from the seventh month of pregnancy do not do too heavy, too intense work and exercise, reduce household chores; physical fatigue immediately rest, to ensure that sleep and quiet rest at least 8 hours a day, including a half to one hour break at noon; mentality should be stable, emotional ups and downs, feel sick quickly to see a doctor. Take the left side position when sleeping to avoid the uterus compressing the large blood vessels beside the spine, so that the blood in the large veins of the lower limbs can flow back to the heart normally and reduce or prevent the occurrence of edema in the lower limbs. 4.Adhere to the appropriate amount of exercise Regular walking, swimming or showering to enhance the resistance to disease, but at the same time, we should pay attention to the principle of feeling comfortable after exercise. 5.Control the weight but not too much weight gain. Excessive body weight can easily cause hyperemesis. Generally, the weight gain should be controlled within 500 grams per week after 28 weeks of pregnancy. Excessive weight gain may be combined with gestational edema, and you must see a doctor immediately. Gestational hypertension is very bad for both the pregnant woman and the child, so be sure to take precautions before it happens! If you feel unwell, you need to seek help from your doctor in time.
