I Have An Elevated White Blood Count Almost 12 Was

I have an elevated white blood count almost 12 was the number. I've been having a hard time eating because once it hits my stomach I'm sick or I throw up and have dry heeves.ive lost 12 lbs in one week. I had the sleeve gastric surgery 2+ years ago and I've gone from 315 to 218 now and about 30lbs excess skin
I had a scope done in June and was told I had a hernia and wonder if that got worse for me to feel sick all the time. It's hard to eat knowing it will make you sick. Any suggestions??
