Constipation is a very common problem in the United States, and has numerous causes. In order to understand them, we need to learn a little more about how our bodies function. You may not know it, but there is an extensive nervous system in your intestines. There are actually more neurons in the intestinal or enteric nervous system, than in the central nervous system, which includes the brain and spinal cord. Certain chemicals in your brain, like serotonin, also play a role in coordinating movement in the intestines. Usually, the intestines have a normal wave-like movement (peristalsis). When this normal movement is interrupted, the bowel can't empty and there may be bloating, pain, spasm or constipation.
Keeping the colon hydrated
One of the main purposes of the colon (section of intestine before the rectum, also know as the large intestine) is to reabsorb water. In order to prevent the stool from becoming too dry (dehydrated) and inhibiting motility, you need to drink a lot of water—approximately 50 ounces (about 6 normal glasses, or 1.5 liters) a day. Take a look at a one liter size bottle of soda for a general idea. If you are exercising, pregnant, or if the weather is very hot, you may need to drink even more. Other beverages, like decaffeinated tea, also work to rehydrate the body, but beverages like alcohol and coffee do not. In fact, they actively dehydrate the body instead of replenishing necessary fluids.
Be conscious that in certain medical conditions—like congestive heart failure, liver disease or kidney disease—too much water can be harmful, so if you suffer from any serious medical problems you should ask your doctor before greatly increasing your water intake.
