Pseudomonas infection: Pseudomonas is the germ that lives in soil and water. If your immune system is weakened for some reason Pseudomonas infection may occur.

According to research Pseudomonas infection can cause green-hued urine (2).

Jaundice: Bilirubin count of the body increases abnormally because of jaundice. During oxidation of bilirubin, it creates a compound called biliverdin.

When the biliverdin is released with urine the pigments of it may cause the change of urine color from light yellow to green.

Green Jaundice: A genetic defect in the biliverdin reductase-A (BVR-A) gene may cause green jaundice. Green urine is a common symptom of this disease (3).

Hypothermia: Our body’s heat generation power decreases during hypothermia. Research has shown that hypothermia may promote green urine (4).

Additional causes of ketosis green urine: Furthermore some additional issues may cause green urine during ketosis. These are:
