GI- Bulk, osmotic, stimulant laxatives Flashcards
bulk forming laxatives
e.g. ispaghula husk and methylcellulose, which work in the same way as dietary fibre; they increase the bulk of your stools (faeces) by helping them retain fluid, encouraging your bowels to push the stools out
osmotic laxatives
e.g. lactulose and polyethylene glycol, which soften your stools and make them easier to pass by increasing the amount of water in your bowels
stimulant laxatives
e.g. bisacodyl, senna and sodium picosulfate, which speed up the movement of your bowels by stimulating the nerves that control the muscles lining your digestive tract

darker urine, dehydration
