The kidneys play a vital role in maintaining our overall health by filtering waste products and excess fluids from the blood. When the kidneys are functioning properly, they produce urine that is typically pale yellow in color. However, when the kidneys are failing, the color of urine can change, indicating a potential problem. In this article, we will explore the different colors of urine that may occur when the kidneys are failing and what they can indicate.
Normal Urine Color
Before we dive into the colors of urine that may indicate kidney failure, it’s essential to understand what normal urine color looks like. Normal urine is typically pale yellow or amber in color due to the presence of a pigment called urobilin. Urobilin is a byproduct of the breakdown of hemoglobin in the blood, which is then excreted by the kidneys into the urine.
Factors That Can Affect Urine Color
There are several factors that can affect the color of urine, including:
- Hydration levels: If you are not drinking enough water, your urine may become more concentrated and darker in color.
- Diet: Certain foods, such as beets, rhubarb, and carrots, can change the color of urine.
- Medications: Some medications, such as certain antibiotics and painkillers, can alter the color of urine.
- Medical conditions: Certain medical conditions, such as liver disease, kidney disease, and urinary tract infections, can also affect the color of urine.
Colors of Urine That May Indicate Kidney Failure
When the kidneys are failing, the color of urine can change, indicating a potential problem. Here are some colors of urine that may indicate kidney failure:
Dark Yellow or Amber Urine
Dark yellow or amber urine can indicate that the kidneys are not functioning properly. This color change can occur when the kidneys are not able to remove waste products from the blood effectively, causing a buildup of toxins in the body.
Brown or Tea-Colored Urine
Brown or tea-colored urine can indicate that there is blood in the urine, which can be a sign of kidney disease or kidney failure. This color change can occur when the kidneys are damaged, causing them to leak blood into the urine.
Pink or Red Urine
Pink or red urine can indicate that there is a significant amount of blood in the urine, which can be a sign of kidney disease or kidney failure. This color change can occur when the kidneys are severely damaged, causing them to leak large amounts of blood into the urine.
Cloudy or Foamy Urine
Cloudy or foamy urine can indicate that there is an excess of protein in the urine, which can be a sign of kidney disease or kidney failure. This color change can occur when the kidneys are not able to filter waste products from the blood effectively, causing a buildup of protein in the urine.
Other Signs of Kidney Failure
In addition to changes in urine color, there are several other signs of kidney failure that you should be aware of. These include:
- Swelling in the legs, ankles, and feet: This can occur when the kidneys are not able to remove excess fluids from the body.
- Fatigue and weakness: This can occur when the kidneys are not able to remove waste products from the blood effectively, causing a buildup of toxins in the body.
- Nausea and vomiting: This can occur when the kidneys are not able to remove waste products from the blood effectively, causing a buildup of toxins in the body.
- Shortness of breath: This can occur when the kidneys are not able to remove excess fluids from the body, causing a buildup of fluid in the lungs.
What to Do If You Suspect Kidney Failure
If you suspect that you or a loved one may be experiencing kidney failure, it’s essential to seek medical attention immediately. Here are some steps you can take:
- See a doctor: If you are experiencing any of the signs of kidney failure, it’s essential to see a doctor as soon as possible.

What is the normal color of urine, and how does it change when kidneys are failing?
The normal color of urine is pale yellow or amber, which is due to the presence of a pigment called urobilin. This pigment is a byproduct of the breakdown of hemoglobin in the blood. When kidneys are failing, the color of urine can change due to the buildup of waste products in the blood. The kidneys are responsible for filtering waste and excess fluids from the blood, and when they are not functioning properly, these waste products can accumulate and cause changes in the color of urine.
In the early stages of kidney failure, the color of urine may not change significantly. However, as the condition progresses, the urine may become darker or more concentrated, taking on a brown or tea-colored appearance. This is because the kidneys are not able to filter waste products effectively, causing them to build up in the blood and change the color of the urine.
What does it mean if my urine is dark yellow or amber-colored?
If your urine is dark yellow or amber-colored, it may be a sign that your kidneys are not functioning properly. This color change can be due to a buildup of waste products in the blood, which can occur when the kidneys are not able to filter waste effectively. Dark yellow or amber-colored urine can also be a sign of dehydration, as the body is not producing enough urine to dilute the waste products.
However, it’s essential to note that dark yellow or amber-colored urine can also be caused by other factors, such as certain medications or foods. For example, some medications, such as certain antibiotics, can change the color of urine. Additionally, foods like beets or rhubarb can cause urine to take on a reddish or brownish hue. If you’re concerned about the color of your urine, it’s best to speak with a healthcare professional to determine the underlying cause.
What does it mean if my urine is brown or tea-colored?
If your urine is brown or tea-colored, it may be a sign of advanced kidney disease or kidney failure. This color change is often due to the buildup of waste products in the blood, which can occur when the kidneys are not able to filter waste effectively. Brown or tea-colored urine can also be a sign of blood in the urine, which can be a symptom of kidney disease or other underlying medical conditions.
It’s essential to seek medical attention if you notice a significant change in the color of your urine, especially if it’s accompanied by other symptoms like pain or difficulty urinating.
