Understanding Lactulose and its Mechanism

Lactulose is a synthetic disaccharide, meaning it’s a sugar composed of two simpler sugars: galactose and fructose. Your body doesn’t digest lactulose readily. This is key to its function as a laxative.

Instead of being absorbed in your small intestine, lactulose travels to your colon. Here, bacteria ferment it, producing acids (like lactic acid and acetic acid). This increased acidity draws water into your colon.

The increased water softens your stool and increases its bulk, stimulating bowel movements. This process gently relieves constipation.

The amount of water drawn in and the resulting stool consistency directly relate to the dose of lactulose you take. Higher doses generally produce a more significant effect.

Factor Effect on Lactulose Action
Dosage Higher doses lead to more significant osmotic effects and increased bowel movements.
Gut Flora Individual differences in gut bacteria affect the rate and extent of lactulose fermentation.
Fluid Intake Adequate water intake supports lactulose’s function by providing the necessary fluid for stool softening.

Remember to consult your doctor or pharmacist for personalized dosage recommendations and to discuss any potential side effects.
