Which doctor will guide my 2.4 creatinine?

Your creatinine level is a bit above normal and your eGFR is a bit below normal. These are not a big deal and can occur due to age or some health problems in the past like angioplasty. It may not be visible in the beginning. Thus, living a healthy lifestyle such as eating well, drinking enough water, and making regular doctor visits can greatly assist your kidneys. 

The report suggests, however, that there seems to be a little issue with the right kidney and ureter. The right kidney is a little bit swollen (hydronephrosis) with fluid which is also a bit widened (hydroureter) in the upper ureter. This may be caused by something blocking the urine from the kidney to the bladder. The positive thing is, there are no stones that are causing the blockage. Further tests will help us in this matter, to know what's the cause of the problem. It's vital to do the follow-up tests, to find out exactly what's happening, and to get the proper treatment.

When getting a blood test, it may show if someone has too much 'NIC' in their system. This happens when people eat too many things with salt or if their kidneys are not working well. If you feel thirsty and tired all the time, or if your feet and legs swell up - those could be signs that something is wrong because of too much 'NIC'.

Creatine is produced by the body and generally excreted by the kidneys. A creatinine level over 2.5 can indicate kidney dysfunction. Symptoms may include fatigue or swelling. Conditions such as hypertension or diabetes can lead to this problem. To support your kidneys, ensure sufficient hydration, consume nutritious meals, and adhere to medical advice.
