The bloating cramping and the generally sick feelings that come from constipation can make you miserable. The longer you're constipated the worse your symptoms may become. In addition to being uncomfortable it's also not good for you: one of the ways your body eliminates toxins is through stool; if stool remains in your intestines for an excessively long period of time as it does with constipation your body may start to absorb those toxins.
Constipation can be caused by a low-fiber diet low fluid intake certain medications an inactive lifestyle or holding your bowel movements for long periods of time. Changing these factors may help relieve and prevent your constipation. However some people are especially prone to constipation and may need a little extra help to stimulate bowel movements. Stimulant laxatives can cause you to have a bowel movement but they can also cause severe cramping and aren't intended for long-term use because your body can become dependent on them.
