Why Is My Urine Foamy and Should I Worry About It?

Examining your urine for bubbles is a quick, non-invasive way to assess your overall health. Having foamy urine can be an indicator that short-term or long-term health conditions may be present. While some medical conditions are not concerning, others may need medical attention and treatment. If you notice foamy urine regularly, or it is accompanied by additional symptoms, you should seek medical advice.

What is foamy urine?

Foamy urine has bubbles in it and may appear frothy. It may occur because of the speed at which a person is peeing, as the urine mixes with the toilet water and causes bubbles. However, certain medical conditions may also cause foamy urine.

Is foam in urine normal?

Occasionally, having foamy urine is considered normal but should not be persistent. Regularly noticing bubbles in urine is abnormal and should be evaluated by a medical professional, as frequent recurrence can indicate potential kidney problems or underlying health concerns.

What causes foamy urine?

Foamy urine can result from both temporary and long-term medical conditions. Some factors that may lead to foamy urine include dehydration, kidney disease, urinary tract infections, diabetes, having too much protein in your urine, retrograde ejaculation, medication, and other medical conditions.

Dehydration

Dehydration occurs when a person does not drink enough water, and certain medical conditions or medications may further increase this risk. When dehydrated, urine may appear foamy. Other symptoms of dehydration may include dry mouth, less frequent urination, fatigue, confusion, or dark-colored urine.

Kidney disease

Kidney disease is a medical condition in which a person’s kidneys do not function as they should. This limits the body’s ability to filter out waste and fluid from the blood. There are a variety of diagnoses depending on the severity of the kidney disease. These include chronic kidney disease (CKD), acute renal failure (ARF), acute kidney injury (AKI), kidney stones, infections, cysts, or cancer, among others.

Other symptoms of kidney disease may include fatigue, trouble concentrating, difficulty sleeping, dry or itchy skin, feeling the need to urinate more frequently, blood in the urine, puffiness around the eyes, swelling in the feet, ankles, or lower legs, poor appetite, or muscle cramping.

Urinary tract infection (UTI)

A urinary tract infection (UTI) is an infection of the urinary system, which includes the kidneys, ureters, bladder, and urethra. A UTI occurs when bacteria enter the urinary system. When you have a UTI, you may experience symptoms such as a strong urge to urinate, burning during urination, urinating often but only passing a small amount of urine, or urine that appears cloudy or foamy.

Diabetes

Diabetes is another potential cause of foamy urine. It is a chronic condition where the body cannot produce enough insulin, or the body cannot use the insulin it creates correctly. The symptoms of diabetes may include strong thirst, needing to urinate often, blurred vision, fatigue, and unintentional weight loss.

Protein in urine (proteinuria)

Protein in the urine, also known as proteinuria or albuminuria is typically caused by other medical conditions, such as kidney disease. Besides foamy urine, proteinuria symptoms include swelling in the hands, feet, face, or abdomen.

Retrograde ejaculation

Retrograde ejaculation occurs when sperm does not leave the body through the penis but gets pushed back into the bladder where the urine is stored. Individuals may experience retrograde ejaculation if they have had surgery to the prostate or urethra, have diabetes, multiple sclerosis, injury or surgery of the spinal cord, or pelvic or rectal surgery.

Symptoms of retrograde ejaculation include producing little to no semen after an orgasm or cloudy urine after orgasm, fertility issues, as well as foamy urine.

Medications

Various medications may lead to foamy urine. Some medications that cause bubbles in urine include those used to treat prostate concerns, high blood pressure (or hypertension), or depression. It is important to talk to your medical provider about medication side effects to understand if foamy urine is considered normal and when to report to a medical provider if on certain medications.

Symptoms occurring with foamy urine

Certain symptoms may accompany foamy urine, indicating underlying health concerns. Some symptoms to look for include:

  • Dry mouth
  • Less frequent or more frequent urination
  • Fatigue
  • Confusion
  • Dark-colored urine
  • Producing little to no semen with orgasms
  • Cloudy urine
  • Fertility issues
  • Swelling in hands, feet, face, or abdomen
  • Thirst
  • Blurred vision
  • Unintentional weight loss
  • Urgency to urinate, only passing small amounts of urine
  • Burning sensation when urinating
  • Trouble concentrating
  • Difficulty sleeping
  • Dry or itchy skin
  • Blood in urine
  • Puffiness around eyes
  • Poor appetite
  • Muscle cramping

If any of the above symptoms are present in addition to having foamy urine, consult a medical professional.

How to diagnose the cause of foamy urine

When foamy urine and additional symptoms are present, being assessed by a medical provider can help determine if the foamy urine is normal or a health concern. To assess and diagnose, the medical provider may order a urine test called a urine analysis. This urine test looks at various components, including appearance, how much protein or sugar is in the urine sample, and if bacteria is present. Depending on these results, additional tests may be necessary to confirm or rule out other medical conditions.

Treatment

Depending on the cause of the foamy urine, your healthcare provider may recommend certain treatments or changes to your regimen.

  • If the foamy urine is present because of a full bladder, your doctor may encourage more frequent bathroom breaks throughout the day.
  • If the foamy urine is related to a medical condition, treating that medical condition can reduce or resolve the foamy urine.
  • If the foamy urine is related to medications, your provider may consider switching your medication, reducing your current medication dose, or deem foamy urine as normal because of your necessary medication intake. If that occurs, your provider may indicate when to report back for reevaluation. This could be additional symptoms present, current symptoms progressing, or any new symptoms not discussed here.

There is no medication to treat foamy urine. Treating the cause of the foamy urine will be the focus of your medical provider. When the medical condition causing the foamy urine is better managed, the foamy urine should reduce or completely resolve.

Regardless of the underlying reason for foamy urine, lifestyle changes can reduce your risk or frequency of experiencing foamy urine. These include increasing water intake, taking more regular bathroom breaks, and eating a healthy diet, including a low salt diet, avoiding alcohol and tobacco products, and managing blood sugar levels.

If you are experiencing foamy urine, monitoring and reporting symptoms to your medical provider is important. As you monitor your symptoms, if any symptoms are persistent or if you notice changes in your urine, seek medical advice.
