What is lactose intolerance?
Lactose intolerance is the inability to digest lactose (the primary sugar found in milk and dairy products), due to the shortage/absence of the lactase enzyme.
Lactose intolerance is natural
Most adult animals stop producing lactase post weaning, since milk is naturally only meant to be consumed by infants. Lactose intolerance is perfectly natural, since adult animals / humans are not naturally expected to consume milk products. Certain communities have a higher level of lactose intolerance than others - studies have indicated that lactose intolerance is as high as 90% amongst Asians.
Symptoms of lactose intolerance
Key symptoms of lactose intolerance include bloating, pain or cramps, rumbling sounds in the lower belly, gas, diarrhoea, nausea and vomiting. These symptoms typically develop within 30-120 minutes of consuming dairy products.
