Hi, a friend of mine had an emergency C-section after 3 Days in labour. She wanted a natural birth as she's brought up vegan and not didn't believe in modern medicine. Anyway, recently she's told me that despite her drinking plenty of water , juicing, etc, her urine is dark in colour. It's been since she gave birth to her daughter a year ago. 

She doesn't believe in doctors and refuses to go and check herself out. She's blaming doctors for that C-section and is thinking that it's because of C_section. 

I'd like to know any other things can cause that dark urine? Or is it due to C-section? Thank you.
