At the early stage of high blood creatinine, there are usually no obvious symptoms, or only mild discomfort such as fatigue, back pain, increased nocturia, loss of appetite and so on.
The renal function is not seriously impaired in the early stage of high blood creatinine, at this time the kidneys can still metabolize most of the toxins and water, so there will be no obvious symptoms.
When blood creatinine continues to rise and the kidney continues to progress to stage 5 of chronic kidney disease, the kidney’s function of excreting toxins is affected and the toxins as well as water in the body cannot be excreted in time. In addition to the initial symptoms, such as acute left heart failure, severe hyperkalemia, gastrointestinal bleeding, central nervous system disorders, and even life-threatening may occur.
Therefore, even if the patient has no symptoms, it is still recommended to go to the hospital in time, follow the doctor’s instructions to complete the relevant examinations, with the help of the doctor to clarify the cause and choose the appropriate treatment plan.
