Causes and Risk Factors of Constipation

The common causes of constipation are:

Not enough fiber in the diet - The American Dietetic Association recommends 20 to 35 grams of fiber each day, but the average American eats about 5 to 20 grams a day. Examples of fiber-rich foods are unprocessed wheat bran, unrefined breakfast cereals, fresh fruits (except bananas), dried fruits, vegetables (except potatoes), grainy breads and legumes.

Not enough liquid - Liquids like water and juice add fluid to the colon and bulk to stools, making movements softer and easier to pass. Recommended daily consumption of liquid is eight, eight-ounce glasses (totaling 64 ounces) per day.

Lack of exercise

Medications - Some medications that can cause constipation are: analgesics (Codeine, Demerol, Perocdan), antacids (Maalox, Mylanta), anticholingerics (Donnatal), anticonvulsants (Dilantin), anti-depressants (Tricyclics), Beta-blockers (Inderal, Tenormin) iron and calcium supplements, pain medications, antispasmodics and diuretics.

Irritable Bowel Syndrome (IBS) - IBS is a common condition marked by chronic or occasional diarrhea, alternating with constipation and accompanied by straining and abdominal cramps. (see Health Profile: IRRITABLE BOWEL SYNDROME)

Lifestyle changes, such as pregnancy, aging and traveling

Laxative abuse - A laxative is a food or chemical substance that acts to loosen the bowels by softening and increasing the bulk of bowel contents, increasing the amount of water in the colon and lubricating the intestinal walls. Over time, laxatives can damage nerve cells in the colon and interfere with the colon's natural ability to contract.

Ignoring the urge to have a bowel movement

Diseases such as multiple sclerosis, Parkinson's disease, chronic idiopathic intestinal pseudo-obstruction, stroke, spinal cord injuries, diabetes, under-active and over-active thyroid gland, uremia (excess urine waste product), amyloidosis (accumulation in the tissues/organs of amyloid), lupus, scleroderma (an autoimmune disorder that affects the tissues/organs), colorectal cancer, depression, colon tumors,diverticulosis and Hirschsprung's disease.
