Foam in urine indicates kidneys stress.
A lot of things can cause it
Having foamy urine can actually be normal in some circumstances if not on a regular basis. Foamy urine can be a sign of protein in your urine (proteinuria) which is something you will want to have evaluated by a physician because it could indicate a serious kidney problem.
Here are some other causes of foamy urine that will interest you:
Rapid Urination:
Rapid urination can cause foamy urine due to the fact of large amounts of urine building in the bladder. This causes you to release at a high rate which can cause foamy urine in the toilet.
Presence of Semen:
The presence of semen in urine can be another cause of foamy urine. This can happen in cases of retrograde ejaculation (bladder sphincter not functioning properly). Where the semen is actually forced into the urinary bladder which will possibly cause foamy urine.
Proteinuria:
Proteinuria or significant amounts of protein in the urine are one of the most common causes of foamy urine.
Vesicocolic Fistula :
This is where there is an abnormal connection between the colon and the urinary tract. An edema is formed at the base of a urinary bladder, which then fluid accumulates under the skin and a foam is produced.
Urinary Tract Infection (UTI):
This happens when you have microorganisms attack your urinary tract. When this happens it causes a urinary tract infection which can be a cause of foamy urine you may be noticing. You will most likely notice the foamy urine and as well a burning sensation that goes along with this.
