Is it normal for urine to turn red before menstruation?

Patient's question:

No

Doctor's answer:

Considering it may be a urinary tract infection, urinary tract infections are caused by bacteria (in very few cases, fungi, protozoa, or viruses) directly invading the urinary tract. It is important to maintain good hygiene of the external genitalia. Urinary tract infections often have certain triggers, so it is necessary to carefully examine the patient for conditions such as urinary tract stones, kidney or ureteral abnormalities, etc.
