If you have a definate intolerance to shellfish, can you develop an intolerance to other fish too?

I developed an intolerance to shellfish years ago (which is a huge shame as I love it). I think it might have been triggered by a lobster food poisoning incident at my sister's wedding (what a nightmare that was!), but it might just be part of a general trend I have noticed that as I get older, I seem to develop more intolerances. I was still able to eat other fish (salmon, white fish, tuna).

Last night we had fish for the first time in a long time (my husband doesn't like fish so we rarely eat it). It was plaice. Today I have had very bad diarreah of the type where you can see last night's dinner pass through you totally undigested. This is what happens if I eat shellfish. Now, the rest of the family (including my 1 year old) are all fine and the fish was bought from a reputable place so I know there was nothing wrong with it.

What I am left wondering is if I have now developed an intolerance to fish of all kinds? (though I eat tuna fish - canned - regularly with no problem)

Any ideas?

sometimes it is only the fish with shells. Did you have an allergy or anaphalactic shock

Not an allergy as such - an intolerance I think. Terrible upset stomach - literally purging the whole meal from my system undigested.

its worth trying other fish as u are probably ok. Normally if its shell fish ,it is literally those with shells and i have known people eat ordinary fish. try some fresh tuna..but try a little bit and keep and open mind so it doesnt affect you psychologically
