What is Lactulose?
Lactulose is a synthetic sugar-based medication commonly prescribed to treat chronic constipation and certain liver-related conditions. It works by drawing water into the bowel, making stools softer and easier to pass.
Additionally, Lactulose is used in patients with liver disease to help reduce harmful toxins in the blood, improving overall health and mental function.
How Lactulose Works
Lactulose acts as an osmotic laxative. After consumption:
- It reaches the colon unchanged
- Bacteria break it down into organic acids
- These acids pull water into the bowel
- Stool becomes softer and bowel movements improve
In liver conditions, it helps trap toxins like ammonia and remove them from the body.
