Can you be partially lactose intolerant or is it one or the other. i don't do well with eggs, pizza, and some other foods, but can eat cheese & other?

Not Lactose: The fact that you don't do well with eggs and pizza, but do ok with cheese would tend to go against lactose intolerance (there is no lactose in eggs). You could definitely have some other food sensitivity. Pay careful attention to the ingredients in your food. If you notice that a certain ingredient shows up in every food you do badly with, that's the culprit. Hope this hleps!
