The following foods may act as laxatives. They are more effective at preventing constipation than treating it:
Almonds, Aloe Vera, Apples/Apple Juice, Artichokes, Bananas, Basil, Beets, Blueberry, Carob, Chicory, Chios Mastic(gum), Cranberry, Coconut, Coffee, Cornmeal, Dandelion, Dates, Dried apricots, Endive, Fenugreek, Figs, Flaxseed, Grapes, Kale, Liquorice, Mangos, Molasses, Oranges, Papayas, Parsley, Peaches/Apricots, Pears, Persimmons, Pineapple, Plums, Prunes/Prune Juice, Rhubarb, Rutabagas, Soybeans, Strawberry, Tamarind, Tangerine, Tea, Tomato, Tomato Juice, Vanilla, Walnuts, Watercress, Winter Squash, Yams, Olive oil
Bulk-producing agents
These work on the small and large intestine and generally take from 12 to 72 hours to work. They are also known as bulk-forming agents, bulking agents, and roughage. They make the stool become bulkier and retain more water. Examples are: Metamucil (psyllium husk), Citrucel (methylcellulose), dietary fiber, broccoli, apples, and polycarbophil.
Stool-softeners (surfactants)
These work in the small and large intestine and generally take from 12 to 72 hours to work. They cause fats and water to penetrate the stool, making it easier to move down the digestive system. After prolonged use they become much less effective. They are effective for people with occasional constipation. Examples are: Colace, Diocto (docusate)
Lubricants (emollients)
These work in the colon and take from 6 to 8 hours to work. They make the stool slippery so that it moves down the intestine more easily and faster. Example: mineral oil
Stimulants (irritants)
These work in the colon. These work by stimulating the wave of contractions that pass along the colon propelling the stools along. Under certain circumstances they can be dangerous. Castor oil is sometimes more effective in achieving complete evacuation. Example: Cascara, pholphthalein, Dulcolax (bisacodyl), Senna, Aloin (from Aloe Vera), castor oil, bisacodyl suppository, Microlax.
Castor oil زيت الخروع
This work in the small intestine. It works directly on the mucosa in the intestines and alters water and electrolyte secretion.
Hydrating agents (osmotics)
These make the intestines hydrate (concentrate more water within), thus softening the stool. There are two types:
1. Saline laxatives These work on the small and large intestine and take from 30 minutes to 6 hours to work. They attract and retain water in the hollow of the intestine, the tube of the intestine (intestinal lumen), thus softening the stool. They also increase intraluminal pressure.
Examples: Dibasic sodium phosphate(fleet enema), milk of magnesia (magnesium hydroxide), Epsom salt (magnesium sulfate), monobasic sodium phosphate, sodium biphosphate, magnesium citrate.
2. Hyperosmotic agents These work in the colon and take from 30 minutes to 3 hours to work. Glycerin suppositories and Lactulose are examples. The glycerin suppositories work mostly by encouraging bowel movements by drawing water into the bowel from surrounding body tissues (hyperosmotic action).
Examples: Glycerin suppositories, Sobrbitol, Lactulose, PEG (polyethylene glycol)
Sorbitol
Sorbitol is a sugar alcohol naturally found in fruits. Its chemical properties allow it to have multiple actions within the body. Its sweetening properties allow it to be used as a low-calorie sweetener in medicinal solutions. Its hyperosmotic properties allow it to work as a laxative, drawing water into the colon from surrounding body tissues to allow softening of stool and relieve constipation
Have 2.6 calories per gram. The Food and Drug Administration concurs with this caloric value
The commercial source of sorbitol is the dextrose (glucose) produced from cornstarch.
Sorbitol is used in hard and soft candies, flavored jam and jelly spreads, baked goods and baking mixes, chewing gum and cough drops. FDA regulates the maximum amount of sorbitol permitted in each of these products
Unexpected side-effect of some chewing gums(sorbitol)
Some chewing gum sweeteners have a laxative effect. A study published in the British Medical Journal found that many sugar-free chewing gums have sorbitol, a sweetener. Sorbitol is a laxative which is poorly absorbed by the small intestine. Too much sorbitol intake can lead to significant weight loss.
About Senna Tablets and how it works
This medicine helps relieve occasional constipation. It belongs to a group of medicines called laxatives. It contains sennosides which work by making bowel muscles contract more often and with more force. This increased muscle action moves bowel contents to the rectum to be emptied and relieves constipation.
This medicine is available in the form tablets: chewable tablets or tablets that are swallowed directly by mouth.
Do not take this medicine for more than seven days. You should drink plenty of fluids while you are taking this medicine.
