Gestational hypertension may be associated with genetic factors, immune maladaptation, and vascular endothelial cell damage, and the presence of multiple chronic diseases and multiple pregnancies are high-risk factors for the development of this disease. Hypertension in pregnancy has a certain genetic predisposition, and people with a family history of gestational hypertension have an increased risk of developing the disease; during pregnancy, the disease may occur due to maternal immune maladaptation, resulting in an imbalance of the body’s immune system; and inflammatory mediators secreted by the placenta and the meconium may damage the endothelium of the vasculature, leading to high blood pressure. If the mother has a gestational age of less than 18 or more than 40 years old, multiple pregnancies, diabetes, chronic kidney disease and other diseases, malnutrition or obesity, etc., these are the high risk factors for the occurrence of gestational hypertension. It is recommended that the relevant groups of people do a good job of checking their blood pressure during pregnancy, so that any abnormalities in blood pressure can be detected and dealt with accordingly.
