What is the most common cause of the creatinine and bun to be in the normal range and the GFR to be a low 51?

What is the most common cause of the creatinine and bun to be in the normal range and the GFR to be a low 51?

Inconsistent: By definition, creatinine is not normal if the GFR is 51. GFR is calculated from serum creatinine value and if the GFR is below 90, that equates to higher creatinine than would be normal for that person. ...Read more

Had bloodwork done. Bun/creatinine ratio, ldh little elevated. Hdlcholesteral a little low. Everything else norm. Can smoking and obese cause this?

Had bloodwork done. Bun/creatinine ratio, ldh little elevated. Hdlcholesteral a little low. Everything else norm. Can smoking and obese cause this?

Yes: Smoking and obesity can cause that cholesterol pattern. The elevated ldh is a little unusual; all labs need to be evaluated further by your physician- depends on many things. These findings do provide objective evidence for lifestyle modifications needed to start now, so that cardiologists or cardiac surgeons are not needed in the future. Stop smoking, start exercise- goal 30-45min 5-6 days/wk. ...Read more

Bun 16.Creatinine 1, 41 with GFR of 43. From >60 to 43 in 2 months. Sle. White female 53yo. Can anything cause a false low gfr? No previ kidney issues.

False low GFR: Yes. Some medications like Bactrim (sulfamethoxazole and trimethoprim) can temporarily increase your creatinine level which could falsely lower your gfr. Another is contrast dye for ct scan. It can temporarily raise your creatinine. But if it is not going back to normal after a few days it means there is contrast induced damage to the kidneys. Lupus is a good reason for kidney damage. ...Read more

Mean fluid intake 2.5L,mean urinary output 700ml.Creatinine,BUN,uroanalysis,proteins all normal.No hot days,no much sweating.What could cause low out?

Staying hydrated: You probably began your experiment dehydrated. There are of course "insensible losses" or volume losses that can't be measured-- mostly this is from the humidified breath. That can amount to 0.5 L right there. You also lose water in the stool... You could account for that. Try the experiment when your urine is clear- when you are not mildly dehydrated. I think you will get better results. ...Read more

What can low bun and creatinine indicate when you 21 yrs old?

Several things: Low cr may be completely normal in a young patient and indicates good kidney function. Other causes of low serum cr are low muscle mass, which can occur in very small stature people, advanced age, bed bound individuals, and in patients with cirrhosis. Low BUN can be caused by poor nutrition or increased fluid intake. ...Read more
