Just my own experience here, but a high dose of a common diabetes medication I take normally has me running to the bathroom roughly a dozen times on an average day. This drug class dials that back to something manageable, so between the two things sort of cancel out. My provider says this drug class commonly causes that particular side effect and actually suggests a stool softener for it.
Hair was already thinning before I started, but five weeks in, I haven't noticed any extra shedding or breakage.
Been on continuous birth control for close to five years now. No breakthrough bleeding, so nothing seems to have shifted there.
