When the glomerular filtration rate (GFR) is lower than 60 ml/min, serum
creatinine will go up. In another words, if serum creatinine increases,
glomerular filtration rate is bound to be lower than normal level. For those
whose serum creatinine is normal, their GFR can be normal or lower than normal
level.
If the tests of renal function show that only serum creatinine is increased
while other indicators keep nomal, patients will be asked to receive another
examination three days later during which they must take vegetarian diet.
Besides, they should also accept other necessary examinations like routine
urinary test, renal B ultrasound test, routine blood test and others to
determine whether the kidney is diseased or not.
There are some situations which can drive the serum creatinine up.
1. Patients always carry fatigue in daily life without enough rest and pay
little attention to some life details, all of which can cause a transient
increase of serum creatinine.
2. The loss of water in the body due to fever, sweat or less drinking. The
pachemia in diuresis period reduce the blood volume in kidney and the increase
of serum creatinine may appear at this time.
3. Patients who have suffered from kidney disease before wrongly take some
medicines with renal toxicity, which can lead to increased serum creatinine and
some cases are irreversible.
4. If patients with Renal Insufficiency also suffer from infections including
colds, pneumonia, intestinal tract infection or urinary tract infection, serum
creatinine may show increase within a short period of time.
5. For those patients who have suffered from kidney disease, if the disease
reappear, they may present oliguria and even anuric, which can be accompanied by
Acute Renal Insufficiency, thus driving the serum creatinine up.
6. For Hypertension patients, if the blood pressure is not well controlled,
long-term massive proteinuria will appear and the disease may develop silently
and finally result in the increase of serum creatinine.
Serum creatinine is a very important indicator to the diagnosis of kidney
disease. Through the above introduction, we know some factors which can lead to
the increase of serum creatinine. So in the daily life, we must pay much
attention to those details and live a healthy life. For more information, please
