Hello and thank you for asking HCM.
I have read the symptoms that you have written above and understand your concern.
Changes in the color of the urine and it's smell (like rotten eggs) is a sign of infection,an
urinary tract infection. She might have other symptoms like:
-the urge to urinate
-pain in her lower abdomen,in pelvic region
-low fever
-passing frequent, small amounts of urine
-urge to urinate
Depending on her immune system and the kind of infection she might have 1 or all the symptoms.
If i was her doctor ,i would start her on antibiotics and do a urine culture for the diagnosis.
Also she needs to have plenty of fluids,2-3 liters each day, fresh fruit juice, chamomile tea or rose tea,1 or 2 cups each day.
Probably she needs to do some blood tests to see the function of her kidneys.
But first,she needs to check up with her family doctor/physician to take the prescription with antibiotics.
If you have any other question,please feel free to contact me.
Dr.Endri Katro
