Ketone's in urine - twice in a week, should I be worried?

Hi girls

Just after some advice...

I have now been signed off sick for the rest of the week, as I have a UTI - and on my second course of anti biotics, because the first one havent touched it.

(Bit annoyed as the week I had my midwife I wasnt feeling well - but I think she was running late and didnt check my sample, and wondering if it would have been picked up then!).



Anyway, I saw Dr last week, she said I had an infection. She also asked if I was being sick... anyway, I said no, thought nothing of it.



Yesterday I got a call, saying the sample sent to the lab was bad, and prob needed more anti biotics. So, I dropped in a sample. The Dr asked again if I was being sick, then said I have Ketones in my urine, and she told me to eat more and eat more carbs.



I am confused though - I am eating lots of carbs (in fact, its the only thing I can eat).



Has anyone had this, and do they know what it means?



Thanks
