Reduces severity of acute gastroenteritis

LACTOGG®’s probiotic strain has extensive research data documenting its specific and direct effect in acute gastroenteritis, especially that caused by rotavirus.

Many clinical studies have demonstrated that taking GG probiotic at the first sign of diarrhoea, together with rehydration salt solutions, reduces the severity of the condition.
In one clinical trial, the duration of diarrhoea in patients who took GG probiotic was found to be shortened by 50%.

In 2001, a clinical trial covering 11 hospitals in 10 European countries confirmed that the addition of GG probiotic in rehydration salt solutions not only shortened the duration and severity of diarrhoea, it also reduced the length of hospital stay.

Nearly every probiotic product claims to be effective in improving diarrhoea. But can all probiotic products improve diarrhoea? Clinical studies tested different brands of probiotic and proved that many brands don’t actually work.

A medical team in Italy compared the effectiveness of 5 different brands of  probiotics.

Their findings, published in the British Medical Journal, were startling. The team found that most of the probiotic brands claiming to be effective in diarrhoea were actually ineffective. LACTOGG®’s probiotic strain however was effective and shortened diarrhoea by more than 1½ days.
The doctors’ conclusion was:

Not all commercially available probiotic preparations are effective in children with acute diarrhoea.”

Their advice was that we

“should choose bacterial preparations based on effectiveness data”

The beneficial effects of GG probiotic in diarrhoea are so well established that major medical bodies have highlighted the use of GG probiotic in their guidelines on the treatment of childhood diarrhoea. The medical bodies include the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN), European Society for Paediatric Infectious Diseases (ESPID), the Iberic-Latin American Guidelines Committee and the Academy of Medicine of Malaysia, College of Paediatrics.

The following table lists a selection of professional bodies and medical societies which recommend the use of the GG probiotic in their guidelines.

Besides supportive treatment for acute gastroenteritis, such as oral rehydration fluids, doctors now use  LACTOGG® to actively build up the intestinal barrier, reduce intestinal leakiness, stimulate the immune system and overcome the bad germs that cause diarrhoea.

Some hospitals, like the Cincinnati Children’s Hospital Medical Center in Ohio, USA, have fully adopted the use of GG probiotic as standard therapy for all children and teenagers admitted for acute diarrhoea.

After a bout of gastroenteritis, GG probiotic’s ability to rapidly re-establish the damaged intestinal ecosystem and re-grow the intestinal surface ensures that nutrition is not interrupted.

How should LACTOGG® be taken?

Babies, children & adults:

At least 1 capsule or 1 sachet a day, at the first sign of diarrhoea.

If there is significant vomiting, you may prefer to dissolve the sachet powder into some rehydration solution or to take the capsule apart and just take the powdered contents with some rehydration solution.

When the frequency of diarrhoea is high, repeated and increased doses of LACTOGG® may be taken, to promote colonisation. Continue LACTOGG® until diarrhoea has settled, and then for at least another one week to rebuild the intestinal surface and re-establish the disturbed intestinal bacteria.

As long as there is diarrhoea, remember to continue taking oral rehydration salt solutions, to prevent dehydration.
