Laxative abuse occurs when a patient overuses laxatives in an attempt to have "normal" bowel movements. It is often seen in patients who do not include enough fibre or water in their diets. It may also result from a false belief that frequent bowel movements are necessary. Patients with eating disorders or binge eaters may abuse laxatives to get rid of large meals.
Laxative abuse can have serious effects. It can damage the muscular function of the bowel. It can also drain the body of water, vitamins, and minerals. Loss of minerals and salts can cause an imbalance in the body's electrolyte system. The elderly are most vulnerable to these types of changes. Laxatives can also affect how other medications work.
There are many types of laxatives. Those most dangerous for long-term use include ingredients called cascara sagrada, bisacodyl, castor oil, senna, and phenolphthalein.
Laxatives with these ingredients work rapidly and can cause severe cramps and diarrhoea. Other laxatives work by drawing water into the colon. Examples are lactulose, milk of magnesia, Epsom salts, and brands such as Colonlytely. Dehydration and body chemical imbalance can still occur even though these are somewhat safer.
The safest laxatives are bulk forming agents that contain a crushed seed called psyllium. They are fairly easy to digest, but may cause gas in some people. Many brands exist, such as Metamucil and Fibyrax.
Check with your doctor if you take laxatives frequently. Tapering off may be better than stopping abruptly. Changing to products containing psyllium may help.
TRY THESE NATURAL ALTERNATIVES TO PREVENT CONSTIPATION:
- drink plenty of water with each meal and throughout the day
- eat more fresh fruits, vegetables, and whole grains to increase dietary fibre
- go to the bathroom when you feel the urge (this may occur right after a meal) and
- exercise regularly to promote bowel movements
