High diastolic pressure, which is an increase in diastolic pressure, is also considered hypertension when the diastolic pressure exceeds 90mmHg.

If you have hypertension, it is essential to have a formal medical examination at a hospital, such as blood tests for lipids and glucose to check for diabetes and hyperlipidemia. Blood tests are also done to evaluate liver and kidney functions, to see if there are any kidney diseases causing the increase in blood pressure.

Additionally, under the guidance of a doctor, conduct ambulatory blood pressure monitoring to observe the overall situation of blood pressure increase within 24 hours. Based on the results of the blood tests and ambulatory blood pressure monitoring, determine whether antihypertensive medication is needed and which type of medication to use.

Can high blood pressure be hereditary?

Hypertension has a certain level of heritability, and research indicates that if parents have hypertension, their children’s risk of developing this condition significantly increases. Of course, genetic factors are only one of the reasons for the development of hypertension. The presence of genetic factors does not necessarily lead to hypertension; postnatal environmental factors are also very important. Maintaining good lifestyle habits over time, including healthy dietary habits, regular physical exercise, reasonable weight control, and a positive mindset can help prevent hypertension. Moreover, even without a family history of hypertension, poor lifestyle habits can still lead to the development of the condition.

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.

Causes of pregnancy-induced hypertension

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.

Normal blood pressure, high blood pressure, and low blood pressure ranges.

Normal adult systolic blood pressure is between 90-139mmHg, and diastolic pressure is between 60-89mmHg. When the systolic pressure exceeds 140mmHg and the diastolic pressure exceeds 90mmHg, this condition is medically referred to as hypertension. When the systolic pressure is below 90mmHg and the diastolic pressure is below 60mmHg, this condition is medically referred to as hypotension. Regardless of whether it is hypertension or hypotension, it often causes symptoms in patients, such as headache, dizziness, and fatigue. Therefore, whether it is hypertension or hypotension, one should visit the hospital's department of cardiology for a formal examination. The doctor will assess the situation on-site to determine if treatment is necessary and how to administer it.

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.
