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.

Difference between hypertensive encephalopathy and malignant hypertension

The difference between hypertensive encephalopathy and malignant hypertension can be discerned from their names, indicating they are different conditions. Hypertensive encephalopathy refers to a condition where blood pressure rises sharply in a short period, with diastolic pressure exceeding 120 mmHg and systolic pressure exceeding 200 mmHg. This dramatic increase in blood pressure causes cerebral vasospasm and increased cerebral perfusion pressure, leading to various manifestations of cerebral edema, primarily severe headache, nausea, vomiting, seizures, and even brain herniation. The emphasis is on the rapid rise in blood pressure over a short term and its impact on the brain, specifically cerebral edema. Malignant hypertension also involves a rapid increase in blood pressure to extremely high levels over a short period. However, the focus of malignant hypertension is on the impact on multiple organs throughout the body, including the brain, but also severely affecting the heart, potentially causing acute left heart failure and pulmonary edema. In the kidneys, it can lead to acute renal failure, characterized by reduced urine output or anuria. Thus, malignant hypertension emphasizes the effects on multiple vital organs, whereas hypertensive encephalopathy focuses primarily on the impact on the brain and central nervous system. Hence, there are some distinctions between the two conditions.

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.

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.

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.

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.
