I constantly feel nauseated and bloated and feel sick when I get hungry, what could be wrong with me?

It started about 2 months ago.
First off I felt constant nausea and I also felt bloated every time I ate and just not really hungry at all. I went to the doctor after three weeks of this and he prescribed somac, to reduce gas or something I can’t quite remember. I took this for five days with no improvements so I went back.

The doctor mentioned blood tests and having a look down my esophagus but he first wanted me to try and cut back on white bread and things like that. I was already on soy milk because I thought I’d started to feel sick after having hot drinks with milk in them and cereal with milk in the morning.

So after a while the constant nausea went away and I started getting hungry at the proper times again, but it was when I got hungry that I felt sick and nauseated again. So I was torn between being hungry and wanting to eat and feeling sick and not wanting to eat. Obviously I ate anyway but then after I’d eaten I’d still feel really bloated again.

So I went back to the doctor and had a blood test. I’m waiting on my results now but I was just wondering if anyone had experienced anything like this before and perhaps had any ideas of what could be up?
