Scientific American Supplement, No. 384, May 12, 1883 Large quantities of fluid may excite violent peristalsis with resulting pain. Maintaining Health Formerly Health and Efficiency It is as well to take simple irritants of this kind as some of the irritant foods that will have a tendency to add to their accumulation of fat, though they may increase peristalsis. Psychotherapy 2011-06-19T02:00:20.053Z It will excite downward peristalsis, will dilute the foul contents of the stomach, and will thus aid the escape of these contents into the intestines, which latter require the washing process as well.

Due to Proctitis and Colitis You will also become aware of peristalsis as the water is evacuated vigorously and discover that sensations from a colon hard at work, though a bit uncomfortable, are not necessarily pain. How and When to Be Your Own Doctor When the inflammation starts causing increased bowel contractions—peristalsis—there is a breaking down of the walls of this fecal ring resulting in complete obstruction. Appendicitis Many patients who oversmoke lose their appetites, have disturbances from inhibition of the gastric digestion, and may have an irregular action of the bowels from overstimulation of the intestines, since nicotin increases peristalsis. Disturbances of the Heart There are various stomach affections, represented by an increase or decrease in stomach secretion, and accompanied by pain, discomfort, and decrease or increase of peristalsis.

Due to Proctitis and Colitis However, reduction of food bulk reduces or completely eliminates peristalsis, thus allowing intestinal contents to sit for extended periods. How and When to Be Your Own Doctor The pain is colicky or spasmodic in character, showing that it is due to peristalsis; food of any kind increases the peristalsis; hence the pain becomes more severe after feeding. Appendicitis And even if it did suspend peristalsis for a few minutes, is it not a fact that other natural functions can be suspended for a much longer period, only to be resumed with unabated vigor? The Royal Road to Health Sugars.—Another food material that is a valuable aid to nature for the stimulation of peristalsis is sugar. Psychotherapy 2011-06-19T02:00:20.053Z The emotions may cause an inhibition of the digestive secretions and of intestinal peristalsis. Origin and Nature of Emotions The result is a great increase in muscle tone, acceleration of peristalsis and eventually, after several dozens of repetitions, a considerable reduction of transit time. How and When to Be Your Own Doctor They make the colon's wall rigid and interfere with peristalsis thus leading to further problems with constipation, and interfere with adsorption of nutrients. How and When to Be Your Own Doctor Bulk is especially necessary in the intestinal canal, to supply a certain amount of irritative stimulation, for the purpose of exciting peristalsis. The Royal Road to Health Various things may interfere with peristalsis, and the disturbance of it will almost surely cause some sensation. Psychotherapy 2011-06-19T02:00:20.053Z |
