Is EFGR Value Of 90 Normal?

I am so worried because I have a history of pvc-induced cardiomyopathy, now resolved after an ablation. When I was sick, a doctor told me I would always be in danger of CHF again, and that I would always need to be careful with fluids. Now heart, kidney, and liver function is normal but I fear all the time that my body won't be able to process fluids. In the hospital, when I was diagnosed, water was taken from my hands and I have been afraid to drink normally ever since.
My concerns:
1. Is urine output variable even when intake is the same and there's not excessive sweating? For example, I may drink 20 oz of water and need to urinate three times in the next two hours but then sometimes only once.
2. Is EFGR of 90 normal? My creatinine is only .7 so it seems low. How quickly can these blood values change without a disease process? Would testing from a month ago still be accurate?
3. Would lowered urine output be an advanced sign of kidney issues and therefore unlikely in someone like me with normal bloodwork?
I have had bladder/kidney ulttasound which was normal. Labwork is attached. Thank you.
Normal Kidney function
Detailed Answer:
Hello
Thanks for the query. I have gone through the reports you have attached and it looks like you have normal kidney function. Now let me answer your doubts one by one
1. Excretion of fluid is not only by urine but also through stools, perspiration and expiration. Apart from the amount of fluids you take it also depends on what type of food and the amount of coffee you are drinking. A better way to monitor fluid status is by measuring your weight everyday
2. eGFR of 90 is subnormal however eGFR is not a very accurate method of measuring the GFR. However a serum creat of 0.7 is normal for your age. There is no need to test creat every month. In absence of any disease I recommend you to get a urine routine and creat checked once a year
3. The first sign of kidney disease is most often presence of protein loss in urine, which you do not have.
I hope I was of help, if you have any further doubts please get back to me.
Regards


Can you explain how kidney function would be compromised if heart issues should return? Is it an advanced stage of heart failure and kidney dysfunction where urine output is actually affected? My weight is stable and no visible edema but even when I was very sick, with EF of just 25/30, my weight was stable and I didn't have noticeable fluid retention so I'm pretty terrified about a return of illness without any symptoms.
I know anxiety is playing the major role in my worrying, rather than symptoms, but I keep thinking understanding from a more clinical side why I'm ok now will help me be able to believe I have fully recovered. Thank you so much.
Left ventricular dysfunction
Detailed Answer:
Hello
Thanks for the query
With ejection fraction of 25% you could sometimes notice issues like shortness of breath especially while doing unaccustomed work. Issues of the heart can lead to renal dysfunction as an eventuality but it is mostly in people who are irregular to follow up. Please don't worry about the functioning of the kidney as it is normal, be on regular follow up with your cardiologist and make sure you take medications prescribed without fail.
To answer your question on how heart affects the kidney is very technical and it will be hard for me to write it. However I will be sending you a link which will explain things in simple terms

I hope I was of help, please get back to me with any doubts.

Monitoring weight
Detailed Answer:
Hello
I recommend that you montior your weight as well. Increase in weight acutely ( > 500 g everyday ) means that the body is retaining fluid

Weight monitoring
Detailed Answer:
Hello
It is not necessary to monitor your weight everyday, I suggested this option as it is less cumbersome than measuring your urine output.
Gain of weight after a salty meal or menstrual cycle is mostly because of retention of salt leading to fluid retention. You will notice swelling of the feet and sometimes puffiness of face.
Medical emergency is only when there is large amount of accumulation of fluid leading to respiratory compromise.
