Hi, I have/had leaky kidneys too...and have had for about 15 years. Over the past 12 however, I have really stepped up my control, and I am very proud to say, that on my last drs visit, they told me that I no longer have "proteinurea".
I think, but do not know for sure, thatthis is due to 2 things. Much, much better control, and a drug called ACE inhibitors.
Some Drs believe that all diabetics should be on ACE inhibitors, a, as well as helping BP, they also protect the kidneys. I am not a DR, do I am certainly telling you to take some...but if they haven't discussed them wuiith you, it mighht be wiorth asking?
As you have only just been diagnosed, you are probably styill seeing the side effects of not treating your diabetes...but, now that you are, the hope is that these symptoms, like your morning sickness will subside.
All the best
