Firstly if this persists I will talk to a GP and I know nobody here can give medical advice but...
Is it possible to develop an intolerance to something you have tolerated fine for years? I've noticed lately that after eating eggs I get nausea, abdominal discomfort and diarrhoea. Never bothered me up until the last few months.
Earlier in the week I had two eggs on toast for breakfast and since then I have had a persistent griping feeling in my stomach lining. My appetite hasn't gone but whenever I eat it makes it worse. And I'm usually dashing off to the loo shortly after eating too. It's been going on for 2-3 days now and I feel rubbish. Is this typical of a food intolerance? To me it feels like a bug but seems odd that it started after eating the eggs.
Needless to say I'll be avoiding them from now on!
