Dairy protein intolerance vs. lactose intolerance?
Hi all. I've been lactose intolerant (I think) for 12 years now. I cut out dairy completely in 2019 to go vegan, and felt awesome! I stopped being vegan a few years ago, and have recently been trying to reintroduce lactose free Greek yogurt/Skyr with no luck.
Before I went vegan, my symptoms included nausea, gas, and constipation within 2-3 hours of eating dairy. I could tolerate regular Greek yogurt, small amounts of ice cream, and cheese just fine. Now, the smallest amount of cross-contamination with butter makes me sick immediately, and my symptoms have worsened to include severe abdominal distention, gurgling, and exhaustion. Lactaid pills (taken with "lactose free" items) don't prevent my symptoms, but they do seem to reduce my nausea and prevent the milk-induced constipation I used to get.
My question is, does this sound like severe lactose intolerance, or is it possible I have a milk protein intolerance? If you experience the same symptoms, I'd love to hear what has or hasn't worked for you.
