High Creatine and low GFR

[LLIRREMy]

70 year old female vegetarian who swims 4 - 5 hours/week. Last 2 Creatine labs were 1.8 and 1.5. Last 2 GFR were 47 and 49. History of kidney stones. 7 years ago I had sepsis and had a kidney stone in my right kidney. A nephrostomy tube was placed for 3 months. Should I see a nephrologist?

Check your vitamin D level. Sometimes high creatine could be because your vitamin D level is either too low or too high. If you see your vitamin D level is too low then start taking vitamin D. If it is too high then you need not get so much sun. I am not sure if you swim outside or inside. If you get alot of sun your vitamin D level could be high and cause creatine level to be high. Also, drink alot of water. It will help big time. Drink like 4-5 bottles a day.  Just out of curiosity, do you dink alot of coffee?
