What signals suggest that renal function may be impaired in patients with hypertension?2018-01-14 14:12
The kidney is an important organ that produces urine, and when a kidney goes wrong, it can't continue to "work" properly. Therefore, urine changes may be a precursor of renal disease. The typical characteristics of early chronic kidney disease are mainly a series of changes in urine. For example, a large number of urine foam may be typical proteinuria, urine color abnormalities such as hematuria.
In addition, there is a symptom that we can easily ignore, is the changes in urine volume, including polyuria, oliguria and nocturia increase. The first two cases are relatively obvious, for the nocturia increase in many nephrotic patients have no concept. As a result, neglect often leads to exacerbation of the condition. What early signals suggest that renal function may be impaired in patients with hypertension?
Nocturnal urine increase is one of the typical symptoms: normal people have obvious circadian rhythm, compared with the daytime, the number of nocturnal urination is less, generally 0-2, urine volume is also relatively small. It can be determined as nocturnal urination if it is more than 2 times and more than half the amount of urine during the day.
Why to suffer from hypertensive nephropathy can appear the circumstance that night urination increases?
In the early stage of hypertension, renal arterioles are in a contractile state to regulate renal blood flow. With the continuous progression of hypertension, ischemic renal parenchyma will be caused. As renal tubules are more sensitive to ischemia, the renal tubules are more sensitive to ischemia. As a result, renal tubule damage appears earlier, and the ability of heavy absorption (absorbent urine) decreases, which leads to increased nocturia, low specific gravity urine and low osmotic pressure urine.
Long-term hypertension will eventually lead to glomerulosclerosis, renal function decline, kidney atrophy, and develop to uremia. Blood pressure and kidney function must be monitored regularly to avoid further exacerbation.
