Bulk-Forming Laxatives
Dietary fiber and bulk laxatives with adequate fluid intake are the most physiologic and safest of medical therapies. However, they may be counterproductive in patients with idiopathic slow transit constipation or with constipation associated with irritable bowel syndrome because they often worsen bloating and abdominal distension in these populations.
Dietary Fiber
Dietary fiber in cereals contain cell walls that resist digestion and retain water within their cellular structures, whereas those found in citrus fruits and legumes stimulate the growth of colonic flora and increase fecal mass. Wheat bran is the most effective fiber laxative with a clear dose response on fecal output. Patients with poor dietary habits may add 2 to 4 tablespoons of bran to each meal, followed by a glass of water or another beverage. A laxative effect may not be observed for 3 to 5 days. Patients should be cautioned that large amounts of bran can cause abdominal bloating or flatulence; therefore, they should start with small amounts and titrate slowly to the desired effect.

Constipation on March 15th, 2011
A treatment for constipation is especially relevant for consumers that suffer on a regular basis or cannot bear attendant symptoms. For the overall health it is important to have a regular bowel movement.
If a healthy diet, lots of exercise and common "cures" such as prunes and fluids require several days to take effect and sometimes don't work at all, it might be necessary to take a laxative to restore regularity.
It sometimes might be necessary to visit the doctor to diagnose the cause of constipation.
Diagnosis
If warning signs exist, the doctor should be consulted.
Numerous hormonal disturbances, metabolic disorders and various drugs can cause constipation. Metabolic disorders include diabetes mellitus, an under-active thyroid, reduced potassium or increased calcium levels in the blood. Drugs that can cause constipation include antihypertensive agents, cardiac drugs, iron tablets, antidepressants, hypnotics and diuretics.
If these causes can all be ruled out, so-called functional disturbances of spontaneous intestinal motility are generally responsible in 80 to 90 percent of cases.

Constipation on October 15th, 2010
Constipation is defined as the difficulty of passing stools, incomplete passage, or infrequent passage of hard stools. It can be further defined as having less than three stools per week for women and five for men despite a high residual diet, or a period greater than 3 d without a bowel movement. It can be caused by gastrointestinal disorders, metabolic and endocrine disorders, pregnancy, neurogenic and psychogenic problems, or it could be drug induced.
Laxative Mechanisms of Action
Laxatives promote bowel evacuation by decreasing water and electrolyte absorption, increasing intraluminal osmolarity, or increasing hydrostatic pressure in the gut. Chronic use of laxatives, particularly stimulants, may lead to laxative dependency. Laxative dependency, in turn, may result in fluid and electrolyte imbalances, steatorrhea, osteomalacia, and vitamin and mineral deficiencies. Known as laxative abuse syndrome (LAS), it is difficult to diagnose. Laxative abuse syndrome is often seen in women with anorexia nervosa, depression, and personality disorders and also in elderly patients with quasimedical concerns

Stimulant laxatives are thought to act on the intramural nervous plexus or intestinal smooth muscle. There is some reason to be concerned that prolonged use of any of the stimulant laxatives may damage the myenteric plexus, thereby impairing bowel function. However, at this point there is no direct evidence to
