Over the last few months I've been feeling really sick and uncomfortably bloated after eating certain types of bread products.
It's gotten worse lately and I'm not sure if I should see a doctor.
I first noticed it after eating Pizza Hut pizza as it was more than just feeling full. I usually eat a bread called Oatilicious by kingsmill which doesn't bother my stomach but then I had some white fresh baked bread from the supermarket which made me feel ill and also bagels that I had a couple of days ago.
Saturday we had pizza for tea and all day Sunday I felt sick (but wasn't sick) and really uncomfortably bloated, I was tearful and felt really low and tired. Also I'm burping allot and have very smelly wind! 
This is the worst it's been which is why I'm asking for advice.
I've never knowingly had food allergies and have looked up IBS, Coeliac and Wheat allergies but are these things someone gets at the age of 40?
I am going to stay off bread this week to see if that helps but does anyone have any other suggestions or know what this might be?
