Is appetite a part of ADHD inattentive? We've really been worrying about DS lately (always, but more lately), because he doesn't seem to want to eat. He can just totally not notice that he hasn't eaten anything, and it doesn't even bother him.
I think the issue is that appetite loss is a common side effect of many ADHD meds. We worried about it before starting DD10 on Concerta, but she seems to be fine with it. She may eat a little more at dinner and a little less at lunch, but she's still getting enough calories as far as we can tell.
