Bulking agents, such as psyllium and methylcellulose, are laxatives that help hold water in the stool and add bulk to it. Osmotic agents are laxatives that keep large amounts of water in the large intestine, making the stool soft and loose. Stimulant laxatives contain substances that directly stimulate the walls of the large intestine (such as senna and bisacodyl), causing them to contract. -- American College of Gastroenterology
