High urea-creatinine ratio is divided into physiologic and pathologic conditions. Physiological is seen in high protein diet, usually not very serious; pathological is more serious, mainly seen in pre-renal oliguria such as gastrointestinal bleeding, dehydration, shock, etc., and post-renal factors such as obstruction.
1. Physiological: consuming a lot of high protein food, fever, etc., the urea-creatinine ratio may be high, after removing the related factors, it will usually return to normal, usually not very serious.
2. Pathologic: more serious, need timely treatment. Pre-renal oliguria, the azotemia caused by extra-renal factors, urea nitrogen can rise faster, but creatinine does not rise accordingly, at this time, the urea creatinine ratio > 10:1. pre-renal oliguria, including gastrointestinal hemorrhage, shock, dehydration, etc.; post-renal oliguria is seen in the obstruction and so on.
Patients with elevated urea-creatinine ratio should go to the hospital in time and receive standardized treatment under the guidance of a professional physician to avoid delaying their condition.
