1. One of the early signs is the appearance of swelling over the ankles, feet or legs.
If you push on edoema, it will pit, and this is known as pitting edoema. Because of a reduction in renal function, edoema (salt retention) develops in the thighs, legs, and ankles. Finally, anyone who has recently had pedal edema should see with a nephrologist to have their renal function evaluated.
2. Puffiness around the eyes.
Fluid accumulation in cells or tissues causes swelling or puffiness around the eyes, and it is referred to as blepharitis. A change in urine output is one of the earliest signs that something is amiss with the kidneys. A higher level of protein leakage from the kidneys is more visible in this population. Protein loss causes a decrease in intravascular oncotic pressure, which results in extravascular fluid accumulation in areas such as the eyes.
3. Changes in urine frequency.
The volume of urine that is generated must be regularly checked.. It is possible that your urine flow could decrease or that you will feel the urge to pee more frequently, especially at night (termed as nocturia). Symptoms such as these might indicate that the renal filtration units have been damaged or are soon to be damaged. This might be a sign of a urinary tract infection in males or an enlarged prostate in men, respectively.
4. Foamy urine or blood in urine.
Extreme frothiness in the urine indicates the presence of protein in the urine (which under normal circumstances should be negligible). When the kidney’s filtering function has been or is being damaged, protein and blood cells begin to seep out into the urine. In addition to showing renal failure, blood in the urine can be a sign of malignancy, kidney stones, or any other sort of infection.
5. Backache or lower abdomen pain.
Pain in the back, side, or below the ribs is a common early symptom of a kidney illness such as renal calculus or pyelonephritis. It is also possible that lower abdomen pain is the result of a bladder infection or a ureter stone (the tube connecting the kidney and bladder). This type of symptom should not be ignored and should be investigated further with a conventional imaging scan such as an X-ray KUB or an Ultrasound Abdomen
