1- Foamy Urine
Albuminuria, a condition caused by excessive amounts of the protein albumin in the urine may cause urine to appear bubbly or foamy and may be an indication of kidney disease. Albumin is found in blood and healthy kidneys don’t allow much of this protein to pass from our blood into the urine.
2- Frequent Urination
The urge or need to urinate more often, especially at night, can be a symptom of kidney disease or kidney failure.
3- Dark/Unusual Urine Color
Purple, dark brown, and other dark unusual colored urine, as well as blood in the urine, can be a sign of kidney malfunction.
4- Fatigue
With the kidneys unable to filter properly, higher levels of toxins and other impurities remain in the bloodstream, causing you to feel tired or sluggish. Anemia, a condition resulting in a reduced amount of oxygen supplied to your organs and tissues—caused by a lack of healthy red blood cells in your blood—may also be to blame.
5- Memory or Concentration Issues
Similar to #4 above, anemia can also cause issues with concentration and memory, as your brain may not be receiving enough oxygen.
