ABSTRACT
Lactose intolerance is common among Asian children. This paper
studies the incidence of lactose intolerance among healthy children
in Singapore using oral lactose breath hydrogen test and milk breath
hydrogen test.
It was found that 74.6% of the children had evidence of lactose
intolerance and all the races were similarly affected. There was an
increasing incidence with increasing age. Significantly fewer
children were symptomatic when milk was used as a source of lactose.
Key words: breath test, diarrhoea, abdominal pain, flatulence.
