There are many reasons that can lead to the occurrence of hypertensive disorders during pregnancy. Normally, due to reasons related to the mother herself or being under the age of 18 or over 35, the risk of developing hypertensive disorders during pregnancy may increase. Additionally, dietary and environmental influences such as a high-salt diet, excessive fatigue, and mental stress can lead to the development of pregnancy-induced hypertension. In some cases, after the development of pregnancy-induced hypertension, it may trigger diseases in other organ systems, leading to severe issues with the placenta, causing complications such as placental abruption, hypoalbuminemia, and cerebrovascular accidents.

What is hypertension?

Hypertension is characterized by elevated arterial blood pressure in the systemic circulation, and may be accompanied by functional or organic damage to organs such as the heart, brain, and kidneys. Hypertension can be divided into primary hypertension and secondary hypertension. Secondary hypertension is due to certain identified causes or etiologies, leading to increased blood pressure, accounting for about 5% of all hypertension cases. Conditions like primary aldosteronism, pheochromocytoma, renovascular hypertension, and renin-secreting tumors are examples, and cases where the cause of increased blood pressure cannot be found are also referred to as primary hypertension and hypertensive disease. Currently, the classification and standard for blood pressure in China mostly use a systolic pressure of greater than or equal to 140 mmHg and/or a diastolic pressure of greater than or equal to 90 mmHg.

Emergency treatment for high blood pressure

Hypertension is currently a common and frequent disease, especially among middle-aged and elderly people. It requires the use of proper antihypertensive drugs to lower blood pressure back to a normal range to ensure the blood supply to the heart and brain. If medication is not taken on time, or due to emotional excitement or excessive fatigue, there can be a sudden increase in blood pressure. Immediate use of effective antihypertensive drugs is necessary to lower the blood pressure to a safe range to prevent accidents. In case of a hypertensive emergency, one should go to the hospital for active treatment to avoid life-threatening risks.

What is the blood pressure for gestational hypertension?

Pregnancy-induced hypertension refers to a series of pathophysiological changes caused by elevated blood pressure in women during pregnancy. It is a severe complication of pregnancy that can have serious effects on both the mother and the fetus. The diagnostic standard for hypertension during pregnancy is the same as in non-pregnant periods, that is, a blood pressure greater than 140/90mmHg can be diagnosed as pregnancy-induced hypertension. However, pregnancy-induced hypertension can be classified based on whether it is combined with other conditions, as well as the severity of the condition. Depending on the severity, pregnancy-induced hypertension can be divided into categories such as gestational hypertension, pre-eclampsia, eclampsia, chronic hypertension, and chronic hypertension with superimposed pre-eclampsia. These classifications are mainly based on the severity of the condition, and it is essential to treat pregnancy-induced hypertension with standardized care.

How should one take medicine for high blood pressure?

Patients with hypertension must use effective medications to keep their blood pressure within the normal range to prevent damage to the cardiovascular and cerebrovascular systems. During medication use, patients should not arbitrarily stop taking their medication or switch to different types. It is necessary to regularly monitor blood pressure and adjust the medication dosage or switch types under the guidance of a doctor as blood pressure fluctuates. Randomly stopping medication and discontinuing antihypertensive drugs can cause blood pressure fluctuations and pose greater risks to the body, especially causing ischemia in the heart and brain.
