Hypertension is a common and frequently occurring disease clinically. Mild hypertension often has no clinical symptoms and is usually detected during physical examinations when measuring blood pressure reveals an increase. In cases of severe hypertension, individuals with long-term high blood pressure may experience dizziness, a feeling of pressure in the head, and headaches. In serious cases, symptoms can include tinnitus and palpitations, requiring the use of effective antihypertensive medications for management. If patients with hypertension do not use medications to manage their condition, long-term high blood pressure can cause significant harm to the body, leading to cardiovascular and cerebrovascular diseases, hypertension-induced heart disease, and stroke. (Please use medications under the guidance of a doctor.)

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.

Symptoms of Hypertension in Pregnant Women

During pregnancy, if a pregnant woman develops high blood pressure, initially there are no symptoms, because at the beginning the blood pressure just slightly exceeds 140/90mmHg. If the high blood pressure is only temporary, it generally does not affect the woman's body and therefore, she may not experience any symptoms. As the condition progresses, the symptoms of high blood pressure can cause physical harm to the woman, likely damaging the kidneys and causing proteinuria. The loss of protein can lead to edema in women, and as a result, many women's initial symptoms will appear as generalized swelling, which does not improve with rest. By measuring blood pressure and urinary protein, symptoms of hypertension in pregnant women can be detected. In the later stages of the disease, hypertension may sometimes be accompanied by dizziness, indigestion, and mild pain in the lower abdomen, which are all symptoms of hypertension in pregnant women.

What should be done at the start of hypertension?

What to do at the onset of hypertension, specifically refers to mild early-stage hypertension. Mild early-stage hypertension can be managed through reasonable dietary adjustments and increased physical activity to lower blood pressure to normal levels. Generally, it is not necessary to use antihypertensive medications. Aerobic exercises such as swimming, skipping rope, square dancing, playing table tennis, volleyball, tennis, can increase vascular elasticity and improve blood circulation, thereby achieving a blood pressure-lowering effect. In terms of diet, it is important to focus on low-fat, low-salt, and low-oil intake to reduce the occurrence of arteriosclerosis and decrease blood viscosity, as well as sodium and water retention which can cause elevated blood pressure. Pay attention to rest, avoid overworking, and do not get overly excited. These are effective treatment and prevention methods for initial mild hypertension.

How to lower high blood pressure?

Hypertension is divided into primary hypertension and secondary hypertension. If it is secondary hypertension, removing the factors that cause high blood pressure can cure it. For example, if the hypertension is caused by an adrenal tumor, removing the tumor can normalize blood pressure. However, if diagnosed with primary hypertension, lifelong medication is required. There are many types of medications available, which need to be specifically analyzed based on the individual situation. If the patient primarily has high systolic pressure, it is recommended to use some calcium channel blockers, which are commonly used for elderly patients who primarily exhibit high systolic pressure. If it is primarily high diastolic pressure, some ACE inhibitors or ARBs are suggested. If sympathetic excitement is predominant, some β-blockers can be used. (Medication should be taken under the guidance of a professional doctor.)

Hypertensive crisis blood pressure values

At any stage of hypertension development and other disease emergencies, severe life-threatening blood pressure increases can occur, requiring emergency treatment. Hypertensive crises include hypertensive emergencies and hypertensive urgencies. Hypertensive emergencies refer to severe blood pressure increases within a short time—hours or days—with diastolic pressure greater than 130 mmHg and/or systolic pressure greater than 180 mmHg, accompanied by severe dysfunction or irreversible damage to critical organs and tissues such as the heart, brain, kidneys, retina, and major arteries. Hypertensive urgencies may present as increased blood pressure but without obvious target organ damage.
