What are the signs and symptoms of lactose intolerance?
After consuming dairy, patients with lactose intolerance may develop:
- Abdominal cramping
Symptoms are not immediate, and typically peak in intensity between one to three hours after the meal. People with lactose intolerance have reactions to dairy food that vary in severity. Most patients with lactose intolerance can tolerate one cup of milk at a time, but develop symptoms with larger amounts of dairy consumption. Lactose intolerance does not usually cause weight loss, blood in the stool or persistent vomiting.
