Are you losing weight unintentionally?

I had my PD surgery. I haven't begun PD, only the flushes.

When my CKD got bad, I didn't want to eat at all. As it worsened, I started becoming nauseous. I even began to immediately vomit when I ate something with too much fat, potassium or phosphor. I have cramping due to my potassium. My nephrologist put me on Valtessa, and I lost my appetite even more. Plus now there's concern about constipation so I'm on stool softener and Miralax now.

At some point I now barely eat a few bites before I'm done. Things I would wolf down, I look at warily wondering if it will stay down.

What are you eating that is helping you?

Apples seem ok, but really getting concerned if I can begin training Monday if I don't have proper bowel movement since I drained so slowly on Monday.
