Hi there.
Thank you for choosing HCM for your query.
As you mentioned that your daughter had a stomach bug causing
diarrhea which has resolved and now she is having more urination.
It is common for children especially girls to develop a
urinary tract infection after diarrhea and your daughter is frequently urinating points to the likelihood of a UTI.
That's why it is important that when you wipe your daughter, it is done from front to back to prevent chances of getting UTI.
Also, sometimes the skin around
urethra may get irritated after diarrhea and she may be suffering from a yeast infectioN causing her to have some discomfort and urinate frequently.
I would suggest for her to be seen by her
pediatrician for her to be examined so as to rule out a yeast infection and have a urine analysis if necessary.
Regarding the pelvis being thickened if her
ultrasound was found to be normal, she does not need another ultrasound unless she had frequent urinary tract infections.
HOPE THIS HELPS.
REGARDS,
Dr. Sumeet.
