Your questions about constipation and OsmoLax Relief answered

How do I know if I am constipated?

The main symptom of constipation is a hard, dry stool that is infrequent or difficult to pass.

What causes constipation?

There are many causes of constipation, but the main cause is due to the slow movement of the stools through the bowel. The large bowel absorbs water from the stools when they are not moved regularly and this can result in small or hard, dry stools being formed that are difficult to pass.

How does OsmoLax Relief work?

OsmoLax Relief helps restore the body's natural rhythm. It is virtually unabsorbed so it remains in the bowel increasing the amount of water in the stool. This hydrates and softens the stool, making it easier to pass. The result is a more natural, comfortable and more controlled bowel movement.

When will OsmoLax Relief start to work?

OsmoLax Relief usually takes 1 to 3 days to help restore the body's natural rhythm and produce a bowel movement. It results in a more natural and comfortable bowel movement which allows you to stay in control.
