Kidney deficiency can also cause heart disease? March 10 is World Kidney Day. This year's theme is' protect the kidney, save the heart '. What is the relationship between kidney and cardiovascular disease? As we all know, high blood pressure can harm the cardiovascular system and cause stroke, but many people do not know that the relationship between high blood pressure and kidney disease is also very close. High blood pressure can lead to kidney disease, kidney disease will also show high blood pressure.
Nearly 60% of patients with kidney disease will show elevated blood pressure. But most of the patients have never had a kidney related examination, they often tried many ways to reduce blood pressure, but can not achieve the desired effect, because they do not know that the source of the disease is actually in the kidney.
How can kidney disease cause renal hypertension?
The first is because renin and angiotensin are at fault. When the kidney or renal vascular lesions, the secretion of angiotensin will increase, leading to systemic arteriolar spasm, arteriolar resistance increases, leading to hypertension.
Secondly, the function of water and salt excreted in the human body will be weakened or even lost after the occurrence of renal diseases, resulting in * retention of water and sodium in the body, resulting in increased blood volume and renal hypertension. In addition, patients with kidney disease often have sympathetic excitement, which is also one of the factors leading to hypertension. How to prevent heart and kidney disease
Quitting smoking: to prevent heart and kidney disease, nothing is more important than quitting smoking. Smoking can cause arteriosclerosis, eventually lead to coronary heart disease and renal sclerosis. In addition, smoking is also a risk factor for hypertension, hypertension can also lead to heart and kidney disease.
Control of blood pressure: hypertension aggravates the heart load, which will make the heart hypertrophy, cardiac hypertrophy, and eventually lead to heart failure. Hypertension damages all kinds of blood vessels, even the capillaries in the kidney (also known as glomeruli). Normal people have about 3 million glomerular metabolic wastes. When hypertension leads to glomerular damage, and the number of glomeruli with normal function drops to 300000 (10% of normal), dialysis or transplantation replacement therapy is needed, and heart failure will bring a lot of trouble to dialysis or transplantation patients.
Reasonable diet: diet can follow the anti hypertensive diet - low salt diet, increase the intake of vegetables and low-fat milk. This diet has been shown to reduce blood pressure and maintain a healthy weight.
Timely treatment: kidney disease can affect heart health, and heart disease can also affect kidney health. Therefore, if you have kidney or heart disease, please check another organ in time. It is very important to prevent early and delay the occurrence of complications.
reminder:
If hypertension is found for the first time, we should check whether the kidney has pathological changes, especially if the young and middle-aged people have unexplained hypertension, we should also check the kidney, so as not to delay the disease.
