Adult constipation is most commonly caused by dehydration. Begin by drinking plenty of clean water.

Stimulant laxatives can be used to relieve temporary constipation. Cascara sagrada, LB Extract, LB-X, LBS-II, Liquid Cleanse, and Senna Combination are examples of stimulant laxative products in order of strength. Gentle Move is an excellent product for promoting normal bowel elimination. It tonifies the colon while hydrating it and can improve bowel function when taken over time. Chlorophyll capsules are also a mild laxative that can gradually restore colon function.

Bulk laxatives are preferable for long-term constipation. These include Nature's Three, Psyllium Hulls Combination, LOCLO and Everybody's Fiber. To work properly, these products must be taken with large glasses of water. When combined with insufficient water, they can actually cause constipation.

Some people suffer from constipation as a result of a spastic colon that "clamps down" under stress. Constipation can also be caused by intestinal inflammation, yeast infections, a sluggish liver and gallbladder, poor digestion, and parasites.
