When you often see foam in your urine, particularly one that resembles a bubble of soap and which does not dissipate easily, it might be an indication of protein leakage. Normal healthy kidneys do not allow any protein to be passed to the urine, and thus constant foaminess can be a sign of initial kidney damage.
2/5
Darker urine, deep yellow, brown or tea-coloured urine, may at times indicate a presence of accumulated waste or even blood. Although dehydration is an obvious reason of dark urine, regular discoloration despite proper dehydration can be indicative of kidney failure or some other underlying conditions that require medical intervention.
3/5
Pink, red, or cola-coloured urine may be frightening. This can be a sign of blood in the urine, hematuria. It may develop when filtering units of the kidneys are damaged and this enables the red blood cells to leak into the urine. Though it may also be occured by infections or kidney stones, it must never be overlooked.
4/5
The initial warning sign could be a noticeable change in the frequency of urination, including more frequent urination at night or much less volume. The damaged kidneys may not be able to filter adequately causing some alterations in urine production.
5/5
Cloudy urine or urine with a strong and abnormal smell may be a sign of infection or excess protein. Although food can occasionally cause urine to have a smell, constant cloudiness or a strong odour can be associated with kidney issues or urinary tract infections which require medical attention.
