Common Conditions That Alter Pee Color
Your body goes through many phases in life, and believe it or not, your pee can reflect these changes — almost like a built-in mood ring for your health. Let’s take a closer look.
Pregnancy Pee Color: Does It Change?

Pregnancy changes almost everything in your body, including urine. Some moms-to-be notice their pregnancy pee color looks darker due to increased vitamin intake or mild dehydration from morning sickness. Drinking 8–12 cups of water daily helps restore normal urine color and output by replenishing lost fluids and electrolytes [5].
Hormonal shifts can also make urine appear more concentrated. Pregnancy also increases the risk of UTIs [6]. If your pee is consistently dark or has an unusual odor, check with your doctor to rule out issues like a UTI or gestational diabetes.
Medications and Urine Color
Your medicine cabinet might be the culprit if your urine looks a little off. Here are some common drugs that can affect urine color:
Antibiotics: Some, like metronidazole, can turn pee dark brown [7].
UTI Medications: Drugs like phenazopyridine can give urine a bright orange or reddish tint [7].
Laxatives: Those containing senna may cause a pinkish or reddish hue [3].
Cancer Treatments: Certain chemotherapy drugs can turn urine orange [8].
Antidepressants and Anesthetics: Amitriptyline and propofol can make your pee look blue or green [3].
Always check with your doctor if you’re unsure whether a medication is affecting your urine color.
Ketosis and Urine Color: What Happens When You Burn Fat?
If you’re on a low-carb or keto diet, you might notice your pee taking on a slightly darker appearance or having a stronger smell. This is due to ketones being flushed out of your system. While this is normal, staying hydrated is crucial to help your kidneys process these byproducts efficiently [8].
So, how can you tell whether a change in your pee color is normal or a warning sign of something serious? Here are some tips to help you identify when these changes shouldn't be ignored.
When to See a Doctor
Most urine color changes are harmless, but some warrant a medical check-up. Call your doctor if [3]:
- Your pee is red, brown, or very dark, and you haven’t eaten foods that might cause it.
- You experience pain, burning, or cloudy urine, which may indicate an infection.
- You have foamy or bubbly urine, which can sometimes signal kidney problems.
- Changes in urine color persist without an obvious reason.

Key Takeaways
Urine color is more than just a daily observation—it’s a reflection of your hydration levels, diet, medications, and overall health. A healthy urine color typically ranges from pale yellow to amber, with darker shades often signaling dehydration. But other factors, including pregnancy, certain foods, and medical conditions, can also influence the color of your pee.
During pregnancy, hormonal changes, prenatal vitamins, and increased hydration needs can cause urine to appear darker or more concentrated. Some expectant mothers may notice changes in urine color due to iron supplements or mild dehydration from morning sickness. While most variations are harmless, persistent dark or cloudy urine could indicate an underlying issue like a urinary tract infection (UTI) or gestational diabetes.
Certain foods and medications can also lead to unusual urine colors. Beets and carrots may give urine an orange or reddish tint, while some antibiotics and supplements can cause shades of green or even blue. In rare cases, brown or cola-colored urine may be a sign of liver issues or muscle breakdown.
While occasional changes in urine color are normal, a sudden shift accompanied by pain, blood, or other unusual symptoms warrants medical attention. Paying attention to your urine color can serve as an easy, non-invasive way to monitor your health and detect potential concerns early.
