Bubbles in Urine – Top Causes

Seeing bubbles in urine while at the toilet can cause people to question their health. If you’re worried about the causes, we’re here to help.

Most of the time, this symptom is no big deal. It can be linked to dehydration or chemicals in your toilet. In these cases, a simple change in lifestyle can make all the difference.

There are, however, more serious causes like urinary tract infections or proteinuria. In these cases, you might need to seek help from a medical professional.

We’ll talk about each of these in greater detail below.

Top Benign Causes for Bubbles in Urine

As we mentioned, this symptom is usually not very serious on its own. It’s often associated with the following things:

  • Chemicals in Toilet: When chemicals in your toilet mix with your urine, it can cause bubbles to appear. In this case, there’s nothing to worry about as it has nothing to do with your health. Once you remove the chemicals, the bubbles should disappear as well.
  • Pregnancy: Some women will develop slightly enlarged kidneys when they become pregnant, which can lead to bubbly urine. So, if you’re pregnant and are experiencing this symptom, sit back and relax since you’re most likely okay.
  • Dehydration: Have you been drinking enough water? If not, your urine will become more concentration and this can lead to the formation of bubbles. People with diabetes tend to have more bubbles in urine for the simple fact that they’re at a higher risk for dehydration.
  • Forceful Urination: The last benign reason for why you might have bubbly urine is because you’re urinating too forcefully. This usually happens whenever you hold your urine in too long, causing it to come out faster.

This are the most common benign causes for this symptom. The best recommendation we have is to drink more water. Staying hydrated should make it go away.

Also, pay attention to any chemicals that you’re putting in your toilet since these can also be the cause.

Now that we’ve covered the benign causes, let’s talk about a few that are more serious.

Proteinuria, which means “protein in urine” can cause your urine to develop a foamy appearance.

Top causes include the digestion of protein gaining supplements and drinks.

It’s also possible to eat too much protein (fish, meat, etc.).

Consuming a normal amount of protein per day shouldn’t result in bubbles in urine.

However, once you start overdoing it, don’t be surprised if this symptom manifests itself.

As a rule of thumb, you should be getting about 0.5 grams of protein for every 1 pound of body weight you have.

So, if you weigh 130 pounds, then you should be consuming about 65 grams of protein per day. These are recommendations and not concrete rules.

Bodybuilders, for example, will usually eat double this amount.

Damaged Kidneys

Proteinuria can be caused by damaged kidneys. A healthy kidney will typically remove waste products while keeping proteins within the body.

If your kidneys are damaged, then it’s possible for protein to leak through into urine.

As we just discussed, this can lead to foamy pee. The good news is that checking your urine for protein is quick and easy.

Just visit your doctor and they’ll be able to perform this test for you. If you’re young and healthy, the chances are lower that you’re experiencing kidney problems.

Urinary Tract Infection


Another cause for bubbles in urine is urinary tract infections.

With UTIs, you’ll typically have other symptoms like burning and pain.

The only way to know for sure if this is what you have is to visit a doctor.

If a UTI is the cause for your symptom, then treating it should make your foamy urine disappear.

Your physician will need to perform a urinalysis to know for sure what you have.

If it is a UTI, a round of antibiotics should make it go away.

When Should You See a Doctor?

There’s no absolute rule for when you should see a doctor regarding this symptom. It ultimately boils down to whether you’re experiencing additional symptoms.

Be on the lookout for accompanying symptoms like a sweet taste in mouth or greenish urine.

These could signify something more serious and should be investigated further. If it’s only happening every so often, then you shouldn’t worry about it too much.

However, if it’s happening every day, and you’re having other uncomfortable symptoms, then it’s probably time to see a doctor.

Summary of Causes

To summarize, having bubbles in urine can be the result of dehydration, pregnancy, forceful urination, or chemicals in your toilet.

In more serious cases, it can be the result of damaged kidneys or urinary tract infections, both of which require medical attention.

Above all, don’t stress over it too much as it’s likely not something serious. Consult your primary care physician for reassurance about this.
