Medicines Used for Constipation
Constipation means passing stools less often than usual, or having hard, dry stools that are difficult or painful to pass. It is common and usually linked to low fibre, too little fluid or inactivity. Eating more fibre, drinking fluids and moving about help. A laxative may be used for a short time if these do not work.

Common questions
How can constipation be eased without medicine?
Eat more fibre slowly (fruit, vegetables, whole grains, pulses), drink plenty of fluids, stay active and do not ignore the urge to go. These steps are safe for most people, including in pregnancy, but can take days to weeks to help.
When should I see a doctor for constipation?
See a doctor if there is blood in the stool, unexplained weight loss, constant tiredness, pain or bloating, a sudden change in bowel habit, or if constipation keeps coming back or does not improve with treatment.
Is it safe to use a laxative regularly?
Laxatives are meant for short-term use. If you need one often, see a doctor to look for the cause. Some medicines, such as opioid painkillers, cause constipation, so tell your doctor but do not stop them on your own.
