Patient's Query

Hi doctor,

Recently I had done with my blood work and some of the numbers were off. My eGFR is down to 63, and my liver function tests were elevated. The whole situation is giving me crippling anxiety and I am not sure what to do about it. I have not had blood work done before this test for a long, and all my numbers came back good. I take the tablet Valsartan 160 mg and Amlodipine 10 mg.

Hi,

Welcome to icliniq.com.

The reports are not alarming. Your blood creatinine level is slightly high as it reflects your higher muscle mass as you are fairly heavy, with a body weight of about 144 kilograms. Creatinine level in the blood reflects muscle mass, so people who are overweight tend to have a slightly higher level of creatinine, and those who are underweight tend to have a lower level of creatinine.

eGFR (estimated glomerular filtration rate) values are not very accurate in overweight or underweight individuals, so there is no need to be alarmed. I would advise doing the urine tests first as you take treatment for high blood pressure.

The liver tests are alright. Do you take any protein supplements?

The Probable causes

The probable causes are high creatinine, likely due to increased muscle mass.

Investigations to be done

The investigations to be done are urine routine, urine spot protein, and urine spot creatinine. Repeat the creatinine level after two months wherever possible to see the trend. I would expect it to show very little change.

Probable diagnosis

The probable diagnosis is high creatinine, likely due to increased muscle mass.

Treatment plan

The treatment plan is to continue with medicines for high blood pressure and ensure that your blood pressure is well controlled.

Preventive measures

Take these preventive measures - 1. Try and lose weight. 2. You should not take any pain relieving medicines or alternative treatment. 3. A regular check of blood pressure.

Regarding follow up

Follow-up repeat blood creatinine level after two months.

Patient's Query

Thank you doctor for the reply,

I do not take any supplements of any kind. I will request these urine tests when I return in about three weeks for a follow up visit.

Thank you.

Hello,

Welcome back to icliniq.com.

It is good that you are not taking any protein supplements. Make sure that you take your BP (blood pressure) medicines regularly. You can let me know once the urine tests are done.

Regarding follow up

Follow up with urine tests as advised.

Same symptoms don't mean you have the same problem. Consult a doctor now!
