Lactulose is a synthetic sugar. Doctors prescribe it, and you can also buy it over the counter, to treat constipation.
It works by drawing water into your colon. This softens your stool, making it easier to pass. Here’s how it does that:
- Osmotic effect: Lactulose isn’t digested in your small intestine. It travels to your colon where bacteria break it down, producing acids. Water absorption: These acids attract water into your colon, increasing stool bulk and softening it. Bowel movement stimulation: The increased stool bulk stimulates bowel movements, relieving constipation.
The amount of lactulose you need depends on your individual needs and your doctor’s or pharmacist’s recommendations. Always follow the instructions on the product label.
While generally safe, lactulose may cause side effects such as gas and bloating. These are usually mild and temporary. If you experience severe or persistent side effects, consult your doctor or pharmacist.
Begin with a low dose and gradually increase it as needed, following product instructions. Drink plenty of fluids to help soften stools and prevent dehydration. Consider dietary changes, such as increasing fiber intake, alongside lactulose use for long-term constipation management.
