Hello,
Normally
urine is colorless or pale yellow in color. If you are having dark yellow to
orange urine, then it can be due to many causes. It can be due to dehydration and less intake of fluids, hematuria (blood in urine), biliary tract obstruction, hemolytic anemia, liver diseases such as hepatitis and taking of some medications.
If the darkness of urine remains even after increasing your fluid intake, then these causes need to be investigated.
