I've been Paleo for two months now (No grains, sugar, dairy, legumes). And since day one I've eaten at least one egg a day. I buy cage/hormone free brown eggs from either Trader Joes or Whole Foods.
About a week ago, I noticed a dulling painful belly ache an hour after eating meals with eggs. (It's not a belly ache where it ended in going to the bathroom to feel better, the only thing that helped it go away was time.) I had a cold at the time, so I thought it was just me being sick. But after noticing no tummy problems after meals without eating eggs. I put two and two together. But not before I consumed another carton of eggs first.
I've avoided eggs for a few days now (belly ache free), until yesterday where I was making deviled eggs for Easter and tasted the filling. The belly ache came back not even a few minutes later.
I've never had a problem with eggs in the past and I do love them. They're such a easy go to protein.
Has anyone else had this problem when switching to Paleo?
Try eating just the yolk... you may have a issue with the whites alone (ovo leptins). See if you still have an issue. If that is the case, you may just have to eat something other than eggs, or just egg yolk.
I've had similar symptoms, though in my case it was associated with other pre-ulcer type symptoms. I found that it was the egg white that was the problem and that it was greatly mitigated if I boiled the eggs (how I cook em most of the time) for at least 10 minutes. Also, eating the eggs alone (rather than in a big meal that included starches too) helped (probably due to faster gastric emptying when eating a smaller single-macronutrient meal. Anyway, my problem likely is totally different than yours - just thought I would share in case it sounds similar.
It sounds like you need to change egg brands. Try a dozen Non TJ or WF...just regular supermarket eggs and see what happens.
It is possible that Salmonella enteritidis was in the feed eaten by the chickens and infected the yolk and white of the egg. It is rare but it can happen. The chickens are healthy and the grower doesn't even know there is a problem.
Usually Salmonella is on the shell of the egg if there is any. I have heard of people washing their eggs before cracking to get rid of any exterior salmonella.
I get the stomach issue randomly, it seems. Most of the time, I just make sure the eggs are thoroughly cooked, and that solves the issue. I've noticed that it also seems to occur if I'm eating them in the morning or early afternoon, but never at night.
I have the same issues with eggs. They hurt my belly after eatting them. I can eat eggs when they are cooked in with other things like cake. But after eatting the eggs I feel like I have to run to the bathroom do my thing but my belly still hurts after that and yes I do have to lay down. Found out that after I had my kid I might of got allegoric to eggs so in your case you might be to sorry. Can't eat no part of the egg.
Are you allergic to soy prtein? Do your eggs contain high levels of soy protein? Be advised chickens are not vegetarians by nature; yet many farmers, even the ones that raise free range chickens, feed their chickens strict vegetarian diets that often include high amounts of soy. Some studies indicate soy protein somehow ends up in the eggs. Perhaps your body is challenged to digest soy protein. YMMV.

I have the same problem as well. Noticed it after I did an elimination diet. I have called restaurants to see if it's premixed eggs they use that bother me, but it is actually the reg eggs that are giving me issues. Guaranteed long lasting stomach ache - like 3-6 hours and feels like increased temps in my gut too - when I eat frittatas or omelets. However sunny side up doesn't have the same effect. I'm thinking it's an intolerance brought on by the amount consumed and maybe way they are cooked?
If you ever figure out what it is let me know! Eggs randomly hurt my stomach as well, Long dull pain. I stopped eating them a long time and then tried them again and was able to eat omelets every day for like 3 weeks with no issues. Then suddenly I can't eat them again even after some months. Very annoying!
