Lactose is a kind of a sugar present in dairy products, especially milk. People who are lactose intolerant are unable to digest food that contains lactose. The food is excreted by the body as soon as the patient consumes the offending food.

Symptoms of lactose intolerance

After eating a dairy product, the person experiences one or more of the following symptoms:

  • Diarrhea

  • Abdominal cramps

  • Gas

  • Bloating

  • Gurgling

  • Nausea

Each patient has a different tolerance level. As soon as the tolerance limit is reached, the patient passes the food that he has eaten out.

Lactose and lactase -- the difference

Lactose is, as you know, a sugar present in milk whereas lactase is the enzyme present in the digestive system that helps in the digestion of lactose-rich diets. A lack of this enzyme makes a person lactose intolerant.
