Hi, thank you for writing to Healthcare Magic.
I have gone through your query and understood your concerns.
With this presentation, I think the cause is probably an infection. This could either be bacterial, viral or parasitic. In the tropics, malaria
would likely be the cause but typhoid fever
is not often associated with black colored urine. Black colored urine is resulting from rapid breakdown or your red blood cells. It could still be possible that you had an infection which is not associated with black colored urine and as a result, you took some antibiotics that are not good to your body (may be a case enzyme deficiency like G6PD) leading to black colored urine. Now as a result of black colored urine, you run the risk of kidney injury
if those black substances are not rapidly removed from the body. In my opinion, I would suggest you rush to the Emergency doctor for proper assessment and management.
I hope that answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us.
I wish you good health.
