Lactulose Solution is a natural laxative that helps to gently regulate bowel movements, easing chronic or habitual constipation. It generally begins working in eight to twelve hours but may take up to two days to improve constipation. Constipation can affect anyone at any time, but if left untreated can be serious.

Lactulose solution is an osmotic laxative made up of sugar molecules which are broken down by bacteria in the gut. This increases the acidity of the gut’s contents, which reduces the absorption ammonia. Ammonia in the gut causes water to be drawn into the lower bowel which increases the amount of water in the stools, softening them and making them easier to pass, thus relieving constipation. It can take up to 48 hours for the lactulose to have this effect.

Lactulose does not enter the bloodstream nor is it dissolved by human enzymes. It remains in the digestive bolus, causing retention of water which leads to softer stool. It has a secondary laxative effect in the colon, where it is fermented by the gut flora, producing metabolites which have osmotic properties and peristalsis-stimulating effects.

Lactulose is very sweet and can be diluted if needed. It is not absorbed in to the blood stream and is thus suitable for pregnant women, nursing mothers, the elderly, children and anyone who has recently undergone surgery.

Constipation can occur for a number of reasons including a change of diet, medication, lack of exercise and diseases. Taking Lactulose Solution, increasing your fibre intake, exercising and drinking plenty of fluids can help.
