Many patients who have suddenly increased their urination amount or their
urination frequency are confused on what the matter is. In fact, hypertension
has some effects on kidney polyuria. Next I will introduce this reason
elaborately.
Maybe you have not thought that hypertension, also called as high blood
pressure, has a relation with kidney polyuria(frequent urination). In fact,
there are many reasons that are responsible for polyuria, such as prostatic
hyperplasia, urinary infection, Diabetes, intake of some medicines, etc.
However, in clinical the most common cause for polyuria, especially nocturia,
is induced by hypertension, namely the high blood pressure. So for the patients
with nocturnal polyuria, they should pay special attention to whether they have
symptom of hypertension.
Then you may ask how the high blood pressure induces the polyuria. In fact,
when the blood pressure increases, on the one hand, it could damage the renal
tubule’s function, which makes the urine’s concentration function decreased; on
the other hand, hypertension could lead to the glomerular atherosclerosis.
As a matter of fact, high blood pressure could lead to the kidney damage, and
the main symptom of this damage is just the increase of night urine. In normal
cases, the normal average times for night urine is 0 to 2 times, so if the
urination number is often over 3 times a night, this phenomenon should be paid
much attention.
As for the treatment of hypertension, especially for the aged people’
hypertension, as well as their symptom of nocturnal polyuria, angiotensin
conerting enzyme inhibitors(ACEIs) and angiotensin convberting enzymereceptor
blocker are both effective.
Besides the clinical manifestations such as nocturnal enuresis and diuresis,
along with the decline of urine concentration, the disease may transform to
azotemia, and even Renal Failure(Uremia).
So now we can see that hypertension is not only has a effect on kidney
polyuria, but also, it could damage the kidneys and make renal function
persistently decline to an irreversible stage. Therefore, hypertension should be
paid attention and needed treated as early as possible.
