Body change

In the last couple of weeks I’ve noticed that I’m feeling sick after eating and peeing extra through out the night. Not only that but I have been not wanting to eat as much and now today I had dinner at 6 and at 8 I was starving like I hadn’t eaten all day. This isn’t like me to just not want to eat and feeling sick if I eat or if I don’t in time. Things go from sounding great and then if I don’t eat it within 10 minutes I don’t want it anymore. Has anyone else had this happen?
