Causes of Foamy Urine
Urine is produced by the kidney and it contains several substances, among which toxins from the body. By urinating the body actually flushes away harmful toxins which can become dangerous if retained in the body cells. It is not normal for urine to be foamy, but it sometimes happens. Foamy urine might signalize a serious medical condition or it can have less severe causes. In case it is nothing serious, foamy urine will probably be just an isolated incident. If it persists, medical investigations and urine laboratory tests are needed.
Causes of Foamy Urine
- Forceful urination or concentrated urine - foamy urine can appear in case the liquid intake is reduced and the urine produced by the kidneys is very concentrated. It can also occur when emptying the bladder is delayed. When finally getting to the toilet, urination is forceful and foam might become visible in the toilet. It is advisable to increase liquid intake and to go to the toilet without any delay. If the problem persists, foamy urine is probably caused by something else.
- Proteinuria - it is a term for describing the presence of proteins in the urine. These normally exist in urine in a small amount, but when they go above a certain level, foamy urine might occur. Proteins might reach the urine in case they are not broken down completely in the body or in case the kidneys are unable to filter them. Proteinuria can affect people who take protein supplements or who consume high protein foods. If this is the case, protein intake should be reduced and if foamy urine does not go away it might mean that it has other causes.
- Urinary tract infections - in this case foamy urine is accompanied by other symptoms like frequent urination or burning sensation when passing urine.
- Vesiscocolic fistula - it is a condition implying that the colon and the urinary tract are connected in an abnormal way. As a result, fluid accumulates at the base of the bladder and when urinating, goes out and produces foam. Foamy urine caused by vesiscocolic fistula needs to be medically investigated because it can signalize a more serious problem.
- Semen in urine - although semen might reach the urethra during intercourse, it is improbable to cause foamy urine. This is most likely to appear in case of retrograde ejaculation, a condition in which the sperm reaches the urinary bladder.
Persistent foamy urine needs to be medically investigated. Simple urine or dipsticks tests can reveal the causes of the problem.
