Lactose Intolerance Symptoms

Symptoms of lactose intolerance include nausea, bloating, abdominal pain or cramps, abundant gas, and diarrhea. These symptoms usually begin anywhere from 30 minutes to 2 hours after eating a food that contains lactose.

Symptoms of lactose intolerance can be uncomfortable enough to temporarily interfere with daily activities, however, they do not harm the digestive system and lactose intolerance does not progress to any other disease or disorder.

Lactose intolerance is a condition caused by the inability to digest lactose, a sugar found in milk. The lactose intolerance diet is a diet designed to treat the symptoms that result from undigested lactose.

No single person originated the lactose intolerance diet. Physicians treating symptoms of lactose intolerance have developed this diet through observation and trial and error by their patients.
