Could Light Coloured Stools Be Related To Desmopressin?

I have just begun, in the last 4 days, noticing light colored stools. Each time can have a range of brown to light gray. This just started 4 days ago.
I also have recently been diagnosed with Diabtes Insipidus. I have been taking Desmopressin to help control urine outflow. I've noticed a fixed dosage of Desmopressin may work 12 hours or only 5 hours.
Is this all related? Or is there something else going on?
