If you suffer from chronic pain and are taking narcotic pain medication and/or anti-depressants, then you most likely struggle with chronic constipation.
The following is an excerpt from the book titled ‘The Natural Laxative Cookbook’ by Karin Cadwell, Ph.D., R.N. & Edith White, M. Ed.
Certain medications and dietary supplements, such as narcotic pain-killers, anti-depressants, or aluminum-containing antacids can lead to constipation. People who are immobolized after surgery often become constipated.
There are two different types of fiber - soluble and insoluble. Oat bran which lowers the levels of cholesterol is water-soluble fiber. Wheat and rice bran are insoluble; they are not water soluble. They soften the stool and add bulk to it which helps prevent constipation.
Human beings do not have the enzymes needed to break down fiber. As fiber passes through the intestinal system, it attracts and holds water. The result is that the end product of digestion-feces, or stool-is bulkier and softer and more easily passed when it is higher in fiber.
People who eat high-fiber foods have increased peristalsis. Peristalsis refers to the wavelike motions that move food onwards from the time it is swallowed and as it makes its way down the throat, through the stomach, and all along in the digestive tract. Increased peristalsis means tat waste is moved out of the body faster.
The sensation of needing to have a bowel movement comes from the pressure of the weight of waste building up in the colon. This is a direct result of the amount (especially fiber) in the food that was eaten.
The waste of the person on a low-fiber diet remains in the body for a longer time than that of a person on a high-fiber diet and some of the water is reabsorbed.
