Urine Color Healthy and normal is light yellow. If when you pee you see green urine, you will be surprised.
In most cases, the cause is dye in food or drink. Certain medications can also cause it. However, in rare cases, the cause of green urine is a more serious medical condition.
Urine Color Green Causes Food or drink

The most common cause of green urine is from certain foods or drinks. Vegetables, such as asparagus, can cause green urine in some people.
However, a more common culprit is artificial food coloring added to foods such as candy, popsicles, or icing. According to a report in the Annals of Laboratory Medicine in 2013, if green urine is caused by food, this will be seen within 6 hours after you eat foods that contain dyes and usually will disappear within a day.
Drugs Urine Color Green Causes
Like food, many medicines contain dyes. This can cause urine to appear green as it is filtered out of the body, as explained on the Insider page.
Medications that can make urine green include:
- Elavil or Vanatrip (amitriptyline), which are antidepressants.
- Lipodox or Doxil (doxorubicin), which is a chemotherapy drug used to treat breast cancer.
- Indocin or Tivorbex (indomethacin), which are anti-inflammatory drugs that doctors prescribe to treat pain and arthritis.
- Tagamet (cimetidine), which is used to treat heartburn.
- Phenergan (promethazine), a type of antihistamine to treat allergies, nausea, and motion sickness.
- Dyrenium (triamterene), which is a diuretic used to treat hypertension.
- Rinsapin, a type of antibiotic.
- Diprivan (propofol), which is an anesthetic used during surgical procedures.
- Viagra (sildenafil), a drug to treat erectile dysfunction.
- B vitamins, which are commonly found in multivitamin supplements.
If your urine is green after surgery, this usually only lasts a day or two. However, if you suspect that the cause of green urine is a prescription drug that must be taken long term, talk to your doctor. It’s probably not dangerous, but it’s wise to tell your doctor about any side effects from recently taken medications.
Personal Care Products
Personal care and cosmetic products also contain dyes. If you accidentally swallow it, the color of the urine can turn green.
One example is mouthwash containing thymol. If swallowed, urine can change color. Mint breath fresheners, cosmetics, and products dyed green or blue can also have a similar effect.
No need to worry because the change in urine color in this case is not dangerous. The discoloration will go away once you stop using the product, and it is unlikely that you will have additional symptoms that are worrisome or require medical attention.
Urinary Tract Infection
Reported by Tua Saúde, although most cases of urinary tract infections (UTIs) do not cause changes in urine color, there are some bacteria that can make urine appear green.
Infections caused by the bacterium Pseudomonas aeruginosa, for example, are associated with green urine and are commonly found in hospitalized patients.
In addition to green urine, infected patients may also experience other UTI symptoms, such as pain or a burning sensation when urinating, frequent urination, abdominal and lower back pain, cloudy or foul-smelling urine, and fever.
If you suspect you have a UTI, see a doctor for a urine test and get treatment right away. UTI treatment can vary, depending on the symptoms and bacteria causing the infection.
Liver disease
Bilirubin is a by-product of the breakdown of red blood cells. In healthy people, bilirubin is cleared by the liver. However, if you have liver disease, you may have bilirubin in your urine. This can cause the urine to turn green, reported by MedlinePlus.
If green urine is caused by the presence of bilirubin, you may experience other symptoms of liver disease, such as:
- Jaundice, or jaundice, is yellowing of the skin and eyes.
- Stomach pain, nausea, or vomiting.
- Fatigue.
Immediately see a doctor if you experience the above symptoms because liver disease often requires medical intervention.
Blue Diaper Syndrome
Blue diaper syndrome or blue diaper syndrome is a rare disease that mostly affects babies. This condition occurs when the body is unable to break down tryptophan, a nutrient found in animal-based foods such as milk and eggs. Blue diaper syndrome can cause hypercalcemia, causing blue or green urine.
A child with this syndrome may have difficulty gaining weight, or be diagnosed with failure to thrive, a condition in which the baby does not gain weight or reach developmental milestones. Other symptoms include diarrhea, vomiting and changes in appetite.
Consult with a pediatrician. The doctor may be able to diagnose the disease based on a urine sample. People with blue diaper syndrome need to eat a diet low in calcium, protein and vitamin D.
Test The Image With Contrast Dye
Some medical tests that use contrast, such as methylene blue, can turn urine green. Depending on the type of contrast used, other colors may also be considered, such as blue, red, or pink.
In this case, special treatment is not required. However, you will need to drink plenty of fluids to help remove any remaining contrast quickly.
Familial benign hypercalcemia
According to the Genetic and Rare Diseases Information Center, familial benign hypercalcemia is a condition in which the body is unable to regulate calcium levels. This can cause a lot of calcium in the blood and low amounts in the urine, which may turn green.
This condition is often asymptomatic, but other symptoms can include tiredness and weakness, difficulty concentrating, and excessive thirst.
If you suspect you have this condition, talk to your doctor about the need for a blood test that can diagnose the condition.
When to see a doctor?
While many causes of urine discoloration are harmless and can be caused by food or medication, some urine discoloration requires medical attention.
Red or brown urine can indicate blood in the urine. It’s linked to serious conditions including kidney stones, infections, and even cancer. Even if you only experience this one time change in urine color, see a doctor.
In addition, you should see a doctor if:
- Suddenly have an unusual color of urine that doesn’t go away after about a day.
- Urine that smells bad
- Seeing green or blue urine in a child.
- Accompanied by other symptoms such as fever or weakness.
- Urine is an important indicator of your health.
Generally, the cause of green urine is not a serious condition. However, if you experience it for a long time (at least more than two days), see a doctor so that the underlying condition can be identified immediately.
