Characteristics of Hypertension and Kidney Disease and Renal Hypertension

In life, the development of many diseases will cause complications, such as high blood pressure, which is common in life. If it is not handled properly, it will cause kidney diseases. So let us learn about it together!

1. What is hypertension?

Hypertension refers to a series of symptoms caused by increased systolic or diastolic blood pressure. The occurrence of hypertension is related to the heart, kidneys, brain, and blood vessels.

2. Renal hypertension

In some diseases, hypertension is only one of the clinical symptoms. The cause is clear and it is caused by other diseases. This type of hypertension is called secondary hypertension.

Hypertension caused by kidney disease is the most common. Hypertension can affect the kidneys and cause changes in urine. Kidney disease can also cause increased blood pressure. This type of hypertension caused by kidney disease itself is called renal hypertension.

High blood pressure is common in kidney disease.

3. Characteristics of high blood pressure caused by kidney disease

Hypertension caused by kidney disease is symptomatic hypertension, meaning kidney disease occurs first and then hypertension, or abnormal urine is accompanied by symptoms of hypertension. The characteristic manifestations of hypertension are mostly sudden onset and rapid development (renovascular hypertension), and blood pressure is mostly moderately elevated (renal parenchymal hypertension).

These patients have no family history of hypertension and have obvious renal function damage. Moreover, as blood pressure rises, changes in the fundus appear, and kidney lesions can be detected by X-ray and B-ultrasound examinations.

Therefore, hypertension is closely related to kidney disease and can cause a series of kidney damage.

4. Characteristics of kidney diseases caused by high blood pressure

Long-term hypertension can lead to kidney sclerosis, the onset and severity of which are related to the course, severity and treatment effect of hypertension. In the early stage of mild and moderate primary hypertension, there is no obvious change in kidney structure and function for a long period of time. Generally, mild to moderate renal arteriosclerosis will appear after 5 to 10 years, and then affect the renal unit.

However, about 7% of patients with primary hypertension suddenly experience progressive increase in blood pressure within a short period of time and rapidly develop renal failure.

Generally speaking, patients with mild to moderate hypertension suffer from mild kidney damage and rarely develop renal insufficiency. However, patients with malignant hypertension have varying degrees of kidney damage, which can rapidly develop into renal failure if not treated effectively and early.

Therefore, there are many causal and joint relationships between hypertension and kidney disease. Hypertensive patients should have their kidney function checked regularly, and kidney disease patients should also pay attention to changes in blood pressure.
