Regarding urine color?

Hello, Dr.
Hsu.
I have a history of having kidney stones and have undergone two surgeries.
I have a habit of collecting my urine in a container to observe for any large crystals.
This morning, my urine was a golden yellow color, but by the afternoon, it had turned a tea red color.
Is this a normal phenomenon? Thank you.

More Info

Urine color can vary significantly based on various factors, including hydration levels, diet, medications, and underlying health conditions. In your case, the observation of your urine changing from a bright yellow to a tea-red color after sitting for a few hours raises some important considerations.

Firstly, it is essential to understand that urine can change color due to the concentration of solutes as it sits. When urine is fresh, it may appear lighter in color, but as it stands, particularly if it is concentrated, it can darken. This is often due to the evaporation of water, which leaves behind a higher concentration of waste products, leading to a darker hue. However, a tea-red color is not typical for normal urine and could indicate the presence of blood or other substances.

The fact that you have a history of kidney stones is particularly relevant. Kidney stones can lead to hematuria (the presence of blood in urine), which can cause the urine to appear red or tea-colored. If you are experiencing any pain, discomfort, or changes in urination patterns, it is crucial to consult a healthcare provider. They may recommend a urinalysis to check for blood, crystals, or other abnormalities that could indicate a problem.

Additionally, certain foods and medications can also affect urine color. For example, beets, blackberries, and certain medications can cause red or pink urine. However, tea-red urine is less commonly associated with dietary causes and may warrant further investigation.

In summary, while some changes in urine color can be benign and related to hydration or diet, a persistent tea-red color, especially in someone with a history of kidney stones, should not be ignored. It is advisable to seek medical attention to rule out any underlying issues, such as urinary tract infections, kidney stones, or other renal conditions. A simple urinalysis can provide valuable information and help address any concerns you may have. Remember, it's always better to err on the side of caution when it comes to changes in your health.
