The body's blood vessels are closed, and heart and kidney connected, inside
the blood, the more pressure (BP) is higher. And how much blood volume and blood
on water and sodium, they are controlled by the kidneys, therefore, extremely
important in the kidneys in blood pressure regulation.
We usually eat salt, drinking water, most generate urine through the kidneys.
If too much salt, the kidneys excrete more than ability, salt and water will
accumulate in the body too much, resulting in an increase in blood volume,
leading to high blood pressure. If the kidney is a problem, even if just some
very slight kidney damage, it may also cause its ability to decrease drainage
natriuresis. Thus, kidney disease is a major cause of high blood pressure.
In fact, we usually say hypertension or essential hypertension, the incidence
of very important reason is because the kidneys can not be completely discharged
eat sodium and water, resulting in increased blood volume. So, how by regulating
salt intake and excretion to treat high blood pressure do?
First, we must strictly control the salt intake, daily intake of sodium
chloride controlled at 5 to 6 grams, the equivalent of 2 to 3 coffee spoons.
According to our research, the majority of normal subjects and patients with
hypertension usually eat salt exceed this limit. Therefore, in order to strictly
control the salt intake is actually not an easy task. Because of the salt in the
diet, except when cooking to put salt in many foods already contain salt,
especially pickled foods. So, how do you know that salt intake is appropriate?
Very simple, just check the content of sodium and chloride in the urine of 24
hours a day, 24-hour urinary sodium or chlorine 80 ~ 100mmol, equivalent to 5 to
6 grams of sodium chloride ʱ?? Thus, for high blood pressure and kidney disease,
you should periodically check urine sodium and chlorine, to check whether the
target sodium intake.
Secondly, if the strict control of sodium intake are still not effectively
control blood pressure, and even edema, then rely on diuretics to help. Diuretic
treatment of hypertension is one of the most important of the six
antihypertensive drugs, through the promotion of renal natriuresis and drainage,
reduce blood volume and lower blood pressure.
But for patients who have kidney damage, diuretics should note the following:
① renal response to diuretics may have declined, so often need to increase the
dose. Glomerular filtration rate at 30ml / min or less, commonly used thiazide
diuretics basically no effect, while a new loop diuretics should be used. ②
renal excretion of potassium corresponding decline in capacity, using
potassium-sparing diuretics need to guard against the occurrence of
hyperkalemia. ③ when the glomerular filtration rate, decreased excretion of uric
acid, we need to guard against diuretics cause hyperuricemia.
Salt, high blood pressure and kidney disease! In short, salt is very
important for high blood pressure, and kidney is the mastermind behind both.
Control salt intake, regulate renal excretion of salt, it is an important means
of treatment of hypertension. In addition, any new diagnosis of hypertension,
renal system check aspects must be made to determine whether the blood pressure
caused by kidney disease. At the same time, high blood pressure and often cause
kidney disease, and therefore patients with hypertension should be regular
system checks the kidney area.
