Lactose intolerance and galactosaemia are both conditions that involve problems with breaking down milk sugar.

However, galactosaemia is far rarer than lactose intolerance and has to be treated very differently.

While an individual with lactose intolerance might be able to tolerate some dairy, those with galactosaemia have to remove all dairy products from their diet.

Lactose, the sugar found in milk, is normally broken down by the body into two simpler sugars that can be easily digested. These two sugars, galactose and glucose, are then broken down even further. However, individuals with galactosaemia cannot break down galactose, which causes it to build up in the body along with other harmful chemicals. This can lead to serious illness.

The symptoms of galactosaemia can vary and if left untreated can lead to cataracts, liver disease and kidney problems. However, with proper dietary management, most individuals can enjoy good health.

Those with galactosaemia have to eliminate all dairy and dairy products from their diet. While those with lactose intolerance can enjoy Lactofree products these still contain galactose making them unsuitable for individuals with galactosaemia.

It is also important to avoid food items containing whey and casein as they are derived from milk. Galactose can also even be found in some medicines, particularly tablets, and also need to be avoided.
