What are the main types of laxative?
There are several types of laxative that you can buy without a prescription. The main types are:
bulk-forming laxatives, such as wheat bran and ispaghula husk
osmotic laxatives, such as lactulose and macrogols
stimulant laxatives, such as senna and glycerol suppositories
faecal softener laxatives, such as arachis oil and liquid paraffin
How do laxatives work?
Each type of laxative works in a different way to help relieve or prevent constipation.
Bulk-forming laxatives work by increasing the amount of faeces you have and softening them - the fibre in the bran or ispaghula husk 'bulks out' the faeces. This then encourages your bowels to move and push the faeces out.
Osmotic laxatives work by increasing the amount of water that stays in your faeces as they pass through your large bowel. This makes them softer and easier to pass.
Stimulant laxatives work by speeding up the movements of your intestines.
Faecal softener laxatives work by lubricating and softening the faeces, which makes them easier to pass.

remember people Who don't have constipation they should use only osmotic laxatives n not bulk forming or stimulant type it will make u addicted.
