At what level creatinine is bad or dangerous? Creatinine is one essential test item in blood, because it can reflect whether kidneys are working normally. For healthy adults, their creatinine level ranges from 0.5 mg/dl to 1.2 mg/dl, while people with one kidney usually relatively higher normal creatinine level. If creatinine level increases abnormally, it may be bad or dangerous. Given below is our detailed explanation about this issue. Prefer to talking directly?

Generally speaking, transient High Creatinine Level isn’t dangerous.
Creatinine is generated from creatine during muscle metabolism. Therefore, if people do strenuous exercise or increase their exercise amount suddenly, their creatinine level may be tested out higher than the normal. Besides, nearly all meat contains certain amount of creatine. Therefore, if one person eats too much meat, it may cause more production of creatinine. In these cases, patients don’t need to be worried, because diet and lifestyle modifications are enough to make their high creatinine level come down.
However, if serum creatinine stays in high level persistently, people need to pay highly attention.
Regardless of unhealthy diet or lifestyle habits, creatinine level usually won’t be higher than 1.5mg/dl until more than 50% of kidney function is damaged. According to GFR and creatinine level, kidney disease is divided into five stages.
Stage 1 kidney disease, GFR is above 90ml/min, normal creatinine level;
Stage 2 kidney disease, GFR 60~89ml/min, creatinine level 1.5-2.0mg/dl;
Stage 3 kidney disease, GFR 30~59ml/min, creatinine level 2.1~5.0mg/dl;
Stage 4 kidney disease, GFR 15~29ml/min, creatinine level 5.1~7.9 mg/dl;
Stage 5 kidney disease, GFR less than 15ml/min, creatinine level higher than 8mg/dl.
In stage 1-2 kidney disease, patients usually have no obvious symptoms and problems. However, with the progression of patients’ illness condition, creatinine level increases and patients have more and more problems. From this point, creatine 2.0 or higher is bad.
Of course, for different patients, the answer is different. If your creatinine level is above 2.0mg/dl or you have had some symptoms such as fatigue, kidney pain, swelling, proteinuria, blood urine, etc, you should contact doctor immediately to take some medications or treatment for lowering your High Creatinine Level. please Email us at email@example.com to get free evaluation from our kidney experts.
