What is the relationship between kidneys and cardiovascular disease? As is well known, high blood pressure can harm the cardiovascular system and cause stroke, but many people are not aware that the relationship between high blood pressure and kidney disease is also very close. High blood pressure can cause kidney disease, which can also manifest as hypertension.
Nearly 60% of kidney disease patients exhibit elevated blood pressure. But most patients have never undergone kidney related examinations, and they often try many blood pressure lowering methods but fail to achieve the desired results because they do not know that the cause of the disease is actually in the kidneys.
How can kidney disease cause renal hypertension?
Firstly, it's because renin angiotensin is causing trouble. When the kidneys or renal blood vessels undergo pathological changes, the secretion of angiotensin will suddenly increase, leading to systemic arteriospasm and increased arteriolar resistance, leading to hypertension.
Secondly, the function of excreting water and salt in the human body will be weakened or even lost after the kidney is diseased, resulting in the retention of water and sodium in the body, leading to increased blood volume and renal hypertension. In addition, patients with kidney disease often experience sympathetic nerve stimulation, which is also one of the factors leading to hypertension.
How to prevent heart and kidney diseases
Quitting smoking: There is nothing more important than quitting smoking to prevent heart and kidney diseases. Smoking can cause arteriosclerosis, ultimately leading to coronary heart disease and renal sclerosis. In addition, smoking is also a risk factor for hypertension, which can also lead to heart and kidney diseases.
Controlling blood pressure: High blood pressure increases the burden on the heart, leading to cardiac hypertrophy, myocardial hypertrophy, and ultimately heart failure. High blood pressure damages various sizes of blood vessels up to the capillaries (also known as glomeruli) in the kidneys. Normal people have about 3 million glomeruli metabolizing waste in the body. When high blood pressure causes glomerular damage and the number of normally functioning glomeruli drops to 300000 (10% of normal), dialysis treatment is needed, and heart failure can also bring considerable trouble to dialysis patients.
Reasonable diet: The diet can follow an anti hypertension diet - low salt diet, increasing the intake of vegetables and low-fat milk. This dietary pattern has been proven to lower blood pressure and maintain a healthy weight.
Timely medical attention: Kidney disease can affect heart health, and heart disease can also affect kidney health. Therefore, if you have kidney or heart disease, please seek medical attention and check for another organ in a timely manner. Early prevention and delaying the occurrence of complications are particularly important.
When hypertension is first discovered, it is necessary to check for kidney lesions, especially in young and middle-aged populations. If unexplained hypertension occurs, it is even more important to check the kidneys to avoid delaying the condition.
