A protein in your urine needs further evaluation. This protein could indicate a serious kidney problem when it is found in increasing amounts. Your doctor will recommend a urine test to check for increased levels of this protein.

You will have to take further tests if this one comes back positive. It is an indication that something is wrong, and it is important to find the cause and follow the necessary treatment.
Summary
Most of the time, urine will be some kind of a yellow color that is also flat. Multiple factors can influence its color and composition, such as diets and diseases.

See below, where we will present you with 4 reasons for foamy and bubbly urine when going to the toilet. and also indicate if you should be immediately worried.
Why is my pee foamy?

One of the most common reasons for foamy urine is the increased speed at which it hits the water. This happens as it hits the toilet quickly. This foam is clear and should clear up quickly. But it can also be foamy when it is concentrated.
If you are dehydrated or haven’t had enough water to drink, your urine can also be foamy. It indicates that you have too much protein in the urine, such as albumin. This protein creates foam when it reacts with the air.
The role of your kidney is to filter the excess water and waste from your blood into your urine. But proteins are too big to fit through the filters of your kidney, so they stay in the bloodstream. However, they won’t filter as well as they could once they are damaged.
Too much protein can enter your urine if the kidneys are damaged. It is a sign of chronic kidney disease or even late-stage of kidney damage. Another cause of the foam could be Amyloidosis, a rare condition that causes kidney problems.
Reasons for foamy, bubbly urine

The symptom of bubbles in urine is common for both men and women, and there is almost no difference between the genders. There are many causes why foam is forming, and some of them are:
1. The speed
It is one of the most common reasons. A rapid stream of urine will enter the toilet bowl and cause bubbles and foam to form. This foam will clear up quickly and should not be a cause of concern.
2. Dehydration
Drinking water is essential, and dehydration is a symptom of too little water intake. As a result, it can be foamy and bubbly. It happens because it is now concentrated and can get a spike in protein levels.
3. Kidney problems
A condition known as proteinuria will increase the amount of protein in your urine. It happens due to kidney problems, a serious cause of concern. Protein is present in everyone’s urine, but only large quantities will produce foam. In this case, everyone should seek the help of a doctor.
4. UTI medication
There are some medications intended for relieving pain caused by UTIs. This medicine has an active ingredient that will cause foaming in both women and men.
Foamy vs. bubbly urine

Foamy and bubbly urine are basically the same symptoms of a problem related to your kidneys. There are several reasons why you have foamy or bubbly urine.
A fast stream will make it look bubbly simply because you had a full bladder which released a strong stream. Most of the time, a single layer of foam will form, which disappears naturally. It is normal, and it happens to both men and women.
If you use cleaning products for the toilet bowl, bubbles can appear. It happens only because of the chemical reaction between your urine and the solutions used for the toilet. It is not related to any medical problem or condition.
Foamy | Bubbly |
White | Bubbles are bigger |
Stays in the toilet after flushing | Clear |
Sign of protein in the urine | Flushable |
Could be a kidney issue | |
Potentially caused by lupus or diabetes |
You might get dehydrated if you do not drink enough water. Because of this, you might experience bubbly urine. It happens because it is more concentrated and darker than normal. The kidneys will also have trouble filtering the blood properly if the blood glucose levels are too high.
It happens with people suffering from diabetes. Glucose and protein molecules from the blood will end up in their urine, making it foamy and bubbly. Lastly, kidney diseases can also manifest through this symptom. If you notice foam on a regular basis, it is a good warning sign that something is wrong.
You should see a doctor and tell them about your problem’s frequency. Most likely, they will conduct a test, and you will proceed with specialized treatment after the results come.
What causes it?
Kidney failure is one of the reasons why urine can be foamy. The vital function of your kidneys is to filter the proteins from your blood. To maintain essential functions in the body, these proteins are essential.
Proteins can leak from the kidneys into the urine when a person has kidney damage. A functional kidney will not allow large quantities of proteins to pass into urine. However, if the kidney is damaged, this protein will pass through the filter.
If it is persistently foamy, it might be a good indication of proteinuria. It can be one of the symptoms signifying kidney disease. This disease has many more symptoms, and they can vary from person to person. Some of them are:
- itchy skin
- vomiting
- frequent urination
- swelling
- unexplained fatigue
- shortness of breath
- nausea
If you have at least three of these symptoms, you should contact a doctor and make an appointment for testing. If left untreated, such conditions can get worse with time.
Diabetes

Type 1 and type 2 diabetes can induce high blood sugar. It will harm the kidneys and their blood vessels, making it hard for them to function well. If too much protein ends up in the urine, it clearly indicates a health problem.
Type 1 diabetes | Type 2 diabetes | |
Caused by | Genetic condition | Mainly lifestyle-related |
What happens | Immune system attacks insulin-producing cells | Unable to make enough insulin |
Symptoms | Appear quicker | Easy to miss as they’re progressive. |
Management | Insulin | Insulin and/or lifestyle |
Just like diabetes, if you have high blood pressure, the force on your blood vessels will affect the kidneys over time, making them less effective in their role. High blood glucose levels will make filtering harder for your kidneys.
The glucose and protein molecules will mix together and end up in the urine, causing it to be foamy. Diabetes affects the way your body turns glucose into energy. Our bodies naturally use glucose for fuel, with the help of insulin. It is a hormone that the body releases naturally when it detects glucose in the bloodstream.
The role of insulin is to take the glucose into the cells, where it can be used as energy or stored.
