Lactose Intolerance Symptoms
Lactose intolerance is the inability to digest significant amounts of
lactose, the predominant sugar of milk. This inability results from a shortage
of the enzyme lactase, which is normally produced by the cells that line the
small intestine. Lactase breaks down milk sugar into simpler forms that can then
be absorbed into the bloodstream. When there is not enough lactase to digest the
amount of lactose consumed, the results, although not usually dangerous, may be
very distressing. While not all persons deficient in lactase have symptoms,
those who do are considered to be lactose intolerant.
Symptoms of lactose intolerance usually begin 30 minutes to two hours after
eating or drinking foods that contain lactose.
- Bloating
- Nausea
- Abdominal cramps
- Gas
- Diarrhea
Symptoms are usually mild, but may sometimes be severe. The severity of
symptoms doesn't seem to correlate with the degree of lactose malabsorption.
Instead, symptoms seem to be related to a range of factors, including ethnicity,
age and digestion rates.
If you have symptoms of lactose intolerance, talk to your doctor. Too many
people diagnose themselves with lactose intolerance, without considering that
their symptoms could be a sign of a more serious illness. Your doctor can help
determine if you have lactose intolerance or a different condition. Devacor
