Welcome to Just Answer and thanks for your question. eGFR stands for Glomerular Filtration Rate. It is a calculated number based on age, race, sex and creatinine level. It is used to track kidney function. A level of 55 is Stage 3 chronic kidney disease. Here is the chart for Chronic Kidney Disease:

Stages of chronic kidney disease



GFR Level

Normal kidney function

Healthy kidneys

90 mL/min or more

Stage 1

Kidney damage with normal or high GFR

90 mL/min or more

Stage 2

Kidney damage and mild decrease in GFR

60 to 89 mL/min

Stage 3

Moderate decrease in GFR

30 to 59 mL/min

Stage 4

Severe decrease in GFR

15 to 29 mL/min

Stage 5

Kidney failure

Less than 15 mL/min or on dialysis

Your treating medical providers will have to determine why your kidneys aren't functioning properly. Some possible reasons are obesity and high blood pressure. Normal weight for your height is 125-168 pounds; overweight is 169-202 pounds and obesity is anything over 202 pounds. Getting these two things under control with a healthy diet and exercise along with blood pressure medication if you have hypertension should improve the numbers.

ok and what do the others mean?
Expert:  A. Schuyler, NP replied 6 years ago.

The creatinine is used to calculate eGFR so one can track the level of kidney failure. ALT is one of the liver enzymes. It is high but not seriously so. One possible cause is non-alcoholic steatohepatitis (NASH) which is fatty liver disease.

should i see a doctor or is this not that serious? and if i dont see a doctor what would you suggest i should do on my own?
Expert:  A. Schuyler, NP replied 6 years ago.

You should be seeing a doctor on a routine basis so you can find out why you have kidney trouble and if the high ALT is from fatty liver or some other disease. You also need to control hypertension if you have it and get on a diet and exercise program. It is a serious matter to have kidney function that low at your age.
