Question: What are the signs and symptoms of lactose intolerance?
Answer: Signs and symptoms of lactose intolerance may include:
1. Bloated stomach.
2. Intestinal gas.
3. Nausea and vomiting.
4. Stomach pain and cramping.
5. Stomach gurgling or rumbling.
6. Diarrhea.
These symptoms come from undigested lactose in your large intestine. It takes between six to 10 hours for food to reach your large intestine after you eat it, and another 24-36 hours after that to travel through your large intestine. So your symptoms might occur up to a day or two after you eat lactose.
