osmosis

osmotically draw water into SI
may cause ab cramping and electrolyte disturbance
Can be dangerous if not overhydrated!!!
Mg Salts
Laxative most likely to decrease absorption of nutrients and fat soluble vitamins
lubricant laxatives- increase water retention in stool by creating a barrier between colon wall and feces to prevent reabsorption
