Hypertension is clinically divided into primary hypertension and secondary hypertension.

Primary hypertension is characterized by elevated blood pressure without other symptoms, and the current clinical diagnostic methods cannot determine the cause of the blood pressure rise, which is referred to as primary hypertension.

Secondary hypertension occurs as a result of other diseases, with the most common being hyperthyroidism, glomerulonephritis, arteritis, atherosclerosis, and other diseases causing high blood pressure.

After the onset of hypertension, effective antihypertensive drugs must be used for treatment. Hypertension is not to be feared, but the damage it causes to the body is.

(Specific medications should be used under the guidance of a physician)

What is the difference between hypertensive nephropathy and renal hypertension?

There are fundamental differences between hypertensive nephropathy and nephrogenic hypertension. Firstly, hypertensive nephropathy occurs due to long-term high blood pressure, leading to complications in the kidneys. Generally, the history of hypertension exceeds ten years, and routine urine tests reveal a relatively small amount of protein in the urine. The main damage lies in the renal tubules, whose reabsorption and concentration functions are impaired. The primary treatment is to control the blood pressure well, possibly in conjunction with medication to protect the kidneys. On the other hand, nephrogenic hypertension originates from nephritis causing high blood pressure and is a form of secondary hypertension. In this condition, controlling blood pressure is particularly challenging. Usually, a significant amount of antihypertensive medication is required. Dietary considerations include a low salt and low fat diet, with daily salt intake limited to about three grams, maintaining regular schedules, and avoiding catching colds.

How to Read a Blood Pressure Monitor for High Blood Pressure

As living standards improve, a blood pressure monitor has become an essential medical device in households. Electronic blood pressure monitors are very convenient for measuring blood pressure, especially for patients with hypertension. They allow patients to measure their blood pressure timely and adjust medication dosages accordingly. How to read a blood pressure monitor varies with different models. Typically, on an electronic blood pressure monitor, the first line displays the systolic pressure, also known as high blood pressure; the second line displays the diastolic pressure, also known as low blood pressure; and the third line displays the heart rate. These readings can help you know your systolic and diastolic pressures.

How to prevent high blood pressure

The main methods to prevent hypertension are as follows: 1. Maintain a balanced diet, avoid long-term excessive intake of sodium salt, and make sure to consume plenty of fresh vegetables and fruits to supplement adequate amounts of potassium salt and dietary fiber; 2. Regularly participate in sports and physical labor, maintain an active lifestyle, avoid a sedentary lifestyle, and prevent significant weight gain; 3. Combine work with rest to avoid repeated fatigue and staying up late; work should be flexible, and ensure sufficient sleep at night; 4. Maintain a good mood, avoid frequent emotional fluctuations, and also avoid long-term mental overstrain; 5. Do not smoke and avoid excessive drinking.

What is the standard for high blood pressure?

The standard for hypertension is a systolic pressure of 140 mmHg or higher and a diastolic pressure of 90 mmHg or higher. Whether it is systolic or diastolic pressure, if either exceeds the normal range, it is considered hypertension. People with hypertension need to actively undergo antihypertensive treatment. Long-term effective control of blood pressure to meet standards is necessary to reduce the harm caused by elevated blood pressure to the body. If high blood pressure is not effectively controlled, long-term elevated blood pressure can cause damage to the heart, brain, and kidney target organs, and even lead to severe cardiovascular and cerebrovascular complications, thus severely affecting the patient's health and even endangering the patient's life.

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.
