Hygienic-Dietary to Prevention and Control Chronic Constipation
To understand the pathophysiology of constipation and can implement a rational treatment, we must first understand the normal process of digestion of food, how they form the stool and what are the factors that regulate their expulsion.
What is Digestion?
Digestion is defined as a set of mechanical processes (chewing, mixing of food and intestinal motility or peristalsis), chemical (enzymatic hydrolysis) and physical (emulsification of fats by bile salts), by which substances are extracted nutritious food and degrade to smaller particles, can be absorbed easily.
At the mouth, ingested food is crushed and mixed with saliva, then passed to the stomach, where it acquired a consistency softer by the joint action of mechanical contractions of the body and gastric juice. In the stomach, proteins are extracted from food and undergo partial hydrolysis.
