Few of us can comfortably leave a meeting or classroom to attend to physical urges. This, unfortunately, has become a major contributor to a constipated society. The solution to this problem is elusive, to say the least. As a general rule, it is a good idea to check with your doctor before using a laxative, especially if constipation is an ongoing problem. Avoid using mineral oil because it can block absorption of key vitamins.
Osmotic laxatives increase the water content in the stool.
These agents are safe to use a few times a month. However, they should not be used too often because they can flush valuable minerals out of your body. Stimulant laxatives are the most powerful and should be used only with great caution. Check the label for ingredients like senna, sennoside, and cascara, which are powerful stimulants. It is best not to use these laxatives except as directed by a physician.
