Lactose intolerance is a condition where adults cannot properly digest lactose, a sugar found in milk and dairy products, due to a deficiency in the enzyme lactase. Symptoms typically include diarrhea, bloating, stomach ache, nausea, and dehydration, which can occur shortly after consuming lactose.
There is no cure for lactose intolerance, but most people are able to control their symptoms by making changes to their diet. Some cases of lactose intolerance, such as those caused by gastroenteritis, are only temporary and will improve within a few days or weeks.
what causes lactose intolerance
Lactose, which has a formula C12H22O11, is a sugar that is found in the milk of mammals; it makes up around 2% to 8% of milk. It was discovered by Fabriccio Bartoletti in 1619, and later identified as a sugar by Carl Wilhelm Scheele in 1780.The human body uses the enzyme lactase to break down lactose into galactose and glucose - which is then absorbed into the bloodstream
