The symptoms described are indicative of lactose intolerance, where the body is unable to properly digest lactose, a sugar found in dairy products.  The patient is most likely deficient in intestinal lactase and is thus, lactose intolerant. The signs and symptoms of lactose intolerance usually begin 30 minutes to 2 hours after eating or drinking foods that contain lactose and include nausea, vomiting, diarrhea, bloating, gas, and painful abdominal cramping.
