Foamy urine can be alarming, but it’s not always a sign of a serious health issue. While occasional foaminess may result from harmless factors like a strong urine stream, persistent foamy urine could indicate an underlying medical condition. In this article, we’ll explore the common causes of foamy urine, including protein-related issues, infections, lifestyle factors, and more.
What Causes Foamy Urine?
Foamy urine occurs when air mixes with urine, creating bubbles. While some causes are harmless, others may require medical attention. Below are the primary causes of foamy urine:
1. Protein in Urine (Proteinuria)
One of the most common medical reasons for foamy urine is excess protein (albumin) in the urine, a condition called proteinuria. This can happen due to:
- Kidney disease (damaged filters allow protein to leak)
- Diabetes (high blood sugar damages kidneys)
- High blood pressure (affects kidney function)
- Preeclampsia (in pregnant women)

2. Urinary Tract Infections (UTIs)
A UTI can cause foamy urine due to bacteria, pus, or white blood cells mixing with urine. Other symptoms include:
- Burning sensation while peeing
- Frequent urination
- Cloudy or foul-smelling urine

3. Dehydration
When you’re dehydrated, urine becomes more concentrated, leading to foamy or bubbly urine. Increasing water intake usually resolves this issue.
4. Sexually Transmitted Diseases (STDs)
Certain STDs like chlamydia or gonorrhea can cause foamy urine due to urethral irritation or discharge mixing with urine.
🔗 Check CDC guidelines on STD symptoms and testing.
5. Medications and Supplements
Some medications can cause foamy urine, including:
- Antibiotics (like penicillin)
- Pain relievers (ibuprofen, NSAIDs)
- Excess vitamin C (increases urine acidity)
🔗 See a list of medications that may cause foamy urine.
6. Kidney Stones or High Creatinine
Kidney stones or high creatinine levels (a waste product filtered by kidneys) can lead to foamy urine due to kidney dysfunction.

Gender-Specific Causes of Foamy Urine
Foamy Urine in Men

- Prostate issues (enlarged prostate can affect urine flow)
Foamy Urine in Women
- Pregnancy-related proteinuria (preeclampsia risk)
- Vaginal discharge mixing with urine
Why Is My Urine Foamy in the Morning?
Morning urine is often more concentrated, leading to temporary foaminess. However, if it happens frequently, it could indicate kidney issues or dehydration.
When Should You See a Doctor?
Seek medical advice if you notice:
✅ Persistent foamy urine (lasts several days)
✅ Swelling in hands/feet (sign of kidney problems)
✅ Blood in urine
✅ Fatigue, nausea, or back pain
