a good afternoon
Good evening, thanks for asking at HealthReplies.com. GFR or glomerular filtration rate is a term used to determine the screening ability of the kidneys. Kidney is one of the heaviest organs in the body because it functions to filter blood all the time. Kidneys that determine which components of the blood must remain in the body, and which must be excreted in the urine.
In this filtering there is a standard filtering rate that one needs to have, and indeed it should be more than 90, exactly 90 mL / minute. With the numbers you have, there is a possibility you are experiencing certain kidney diseases, can kidney failure, kidney infection or something else. Our advice, you should check with your intern doctor first, because it requires a history, physical examination and support, and maybe a recalculation to determine your condition. Only then can the best handling for you be determined. This examination is important, because the drug for kidney disorders can not be redeemed without a doctor's prescription.
Meanwhile, keep a healthy lifestyle by avoiding cigarettes, not taking drugs without doctor's advice, fulfilling fluid needs, and if there are certain symptoms of swelling in the legs and shortness of breath, do not hesitate to check yourself immediately. So, hopefully answering your question.
