Lactose intolerance becomes evident when an organism has a pathologic response to the sugars found in milk and cannot digest the glucose (lactose).
The signs and symptoms of lactose intolerance usually begin 30 minutes to two hours after drinking milk or having dairy products (yogurt, cheese, cream, etc.) or other products containing lactose (pastries, ice cream, chocolate). Some of the most characteristic symptoms of lactose intolerance are: stomachache, nausea, diarrhea and gas and its effects vary from person to person in intensity.
In only one of the three types of lactose intolerance can this disorder be prevented. This can be done by preventing the mentioned diseases, some of which are also congenital. Patients can improve over time with the proper treatment and diet.
