In addition to protein, which can also cause foamy urine

Besides protein, what can cause foamy urine?

Proteinuria: This is a condition in which protein is released in high amounts in the urine. Usually protein is released in small amounts in the urine. When these amounts get high, the urine may appear frothy. This can be a sign of an impending kidney problem because the kidneys are not filtering the urine properly, releasing too much protein. Untreated high blood pressure and diabetes, along with other factors such as toxins, infection, or kidney trauma, can contribute to kidney filtration problems.

Urinary tract infection: If bacteria get into any part of the urinary tract, an infection can occur. In addition to pain, increased urinary frequency and urgency, and a burning sensation when urinating, your urine may also appear frothy. You should see a doctor if you experience symptoms of a urinary tract infection because the earlier treatment starts, the lower the risk of complications.

Kidney disease: Foamy urine can be a sign of kidney disease due to kidney stones or diabetes. A simple urine test will determine if you have kidney disease.

Preeclampsia During Pregnancy: Preeclampsia during pregnancy leads to leg swelling, proteinuria, high blood pressure, and headaches. This can be fatal to both the mother and the fetus, and any symptoms can worsen as the disease progresses.

Bladder fistula: A fistula is an abnormal connection that, when this happens, develops between the bladder and the colon. This allows air, gases and bacteria to enter the bladder. Along with foamy urine, a person with a urinary fistula will often have infections. Symptoms can be similar to those of a urinary tract infection.

Urinating quickly: Urinating too quickly or forcing urine to leak can be responsible for the foamy appearance. This is because air is brought into the stream of urine, which causes the blisters. This type of foam usually disappears within a few minutes.

Concentrated urine: If you are slightly dehydrated, the urine may become more concentrated, making it appear frothy. The easy way to fix this is to drink more fluids.

Toilet cleaner: Sometimes the urine reacts with the toilet cleaner, creating bubbles. If you're not sure if your urine is foaming, or if it's because of the toilet cleaner causing it to foam, you can urinate in a separate container that hasn't been treated with the cleaner and watch for the foam. Semen in the urine: After sex, small amounts of semen remain in the male urethra. This small amount won't cause foamy urine unless the bladder sphincter isn't working properly, allowing the semen to get back into the bladder. In this case, the urine will appear frothy.

Other causes: Other causes of foamy urine include amyloidosis, cancer, chemical poisoning, diabetes, heart disease such as an enlarged heart, high blood pressure, infections, kidney failure, liver disease, lupus, rheumatoid arthritis, sarcoid, and sickle cell anemia.
