Some patients experience redness in their urine after chemotherapy, which makes them very nervous and afraid of blood in their urine. So what are the causes of red urine? Why does my urine become red after chemotherapy?
First of all, the urine is red, and the most important thing to be wary of is hematuria, urinary calculi and urinary tumors can directly cause urinary tract damage, which can then lead to hematuria. Secondly, some hemolytic anemia, because after the destruction of red blood cells, a large amount of hemoglobin is released from red blood cells, resulting in hemoglobinuria, and urine can also be darkened and red. In addition, some foods, such as red heart dragon fruit, are rich in anthocyanins, and eating too much of them can also cause red urine.
In the case of red urine after chemotherapy, in addition to the above conditions, it should also be considered whether it is related to chemotherapy drugs. Some chemotherapy drugs can cause mucosal damage, bone marrow suppression, thrombocytopenia and lead to urinary bleeding, while some drugs such as doxorubicin, epirubicin, and other anthracyclines can also cause redness of urine due to the excretion of the original drug in the urine.
Redness of urine is not uncommon in clinical practice, and it is most important to find the problem, communicate it in time, and find out the cause.
