Clinical Background

Lactose intolerance (hypolactasia) results in the inability to digest lactose, the predominant sugar of milk. This inability results from a shortage of the lactase enzyme in the small intestine. Lactase deficiency is also known as lactase non-persistence.

Lactase enzyme breaks down milk sugar (lactose) into simpler forms (glucose and galactose), which can then be absorbed into the bloodstream.


Lactase activity begins to decrease after weaning due to a natural down regulation of the lactase gene. One-third of the adult population worldwide retains the ability to digest lactose. It is estimated that approximately 15-20% of Western and Northern Europeans, and 90% of Asian, African and native Americans suffer from lactose intolerance. Often the symptoms remain undiagnosed, and, thus lactose intolerance may not be treated for years.


Individuals who suffer from lactae deficiency often present with symptoms similar to IBS which include:


  • nausea

  • flatulence

  • abdominal discomfort, cramps and bloating

  • diarrhoea


Such symptoms can result from intestinal bacteria that hydrolyse ingested lactose to glucose and galactose, which are in turn fermented by the gut flora to produce short chain fatty acids, Hydrogen, and Methane. Lactose itself also has a high osmotic effect which can cause diarrhoea.
