Hello doctor,

My daughter who is just 15 years old has not had her period for the past few months. She got positive for UTI a few months back but never got treated for it. However, she got blood in her urine yesterday. What could it be?

Please help.



Welcome to

Thanks for trusting us about your health care.

I have gone through your history and understood your concern.

Menstrual irregularities in your daughter's case could be due to hormonal imbalance caused by PCOS (polycystic ovary syndrome). PCOS is an endocrinal disorder in which hormonal imbalance will be there due to cysts in the ovary. The symptoms may include facial hair growth and weight gain. As it is a lifestyle disease, she has to change her lifestyle, eat a high-protein diet with lots of vegetables and fruits and exercise regularly.

I also suggest you get her hemoglobin, HbA1c (Glycated hemoglobin), and TSH (thyroid stimulating hormone) level checked and get an ultrasound pelvis to rule out the cause. No need to worry about it and she can take progesterone for withdrawal bleeding. For urinary tract infection, I suggest you get her urine examination and culture and sensitivity test done.

Hope you found this useful, feel free to ask for more information.

Thanks and regards.
