Duphalax Laxative Syrup is a treatment for constipation. It works by making the stools softer and easier to move in the bowel. This is done by drawing water to the stools. No water is absorbed by the body.


What causes constipation?

Constipation can be caused by a number of different issues, and the cause is not always obvious. Constipation is the feeling of slow bowel movements or no bowel movements at all. The potential causes of constipation can include:

  • A lack of exercise
  • Stress or anxiety
  • Having to stay in bed for long periods
  • Pregnancy

  • Certain types of medication

The feeling of constipation can make you feel bloated or heavy. It can also cause headaches.
