Constipation may look like a small problem, but anyone who suffers from it daily knows how painful, embarrassing, and frustrating it can be. Many patients live with constipation for months or even years, not because treatment is unavailable, but because of lack of correct knowledge, fear of medicines, and common myths. One such medicine that patients often hear about but hesitate to use is Duphalac syrup. In this article, we will explain Duphalac syrup uses in very simple language, clear doubts, break myths, and help you understand how this medicine can safely improve your quality of life.
Why Many Patients Continue to Suffer from Constipation

- Avoid medicines thinking they are habit forming
- Try home remedies again and again without relief

Over time, constipation worsens and leads to:
- Piles (hemorrhoids)

Duphalac syrup uses, when understood correctly, can prevent all this suffering.

Lactulose
Lactulose is a special type of sugar that:
