Yes: Ibs comes in many "flavors" as it were including variants with nausea, vomiting, diarrhea, sometimes constipation. Cramps and stomach upset can occur. Do consider diet and food intolerance as well. Try a 2 week experiment going gluten-free and dairy-free. Slowly reintroduce only one back to see if symptoms recur. Be the scientist. Also consider probiotics (yogurt or kefir) as well.
