Reflux


In a strict sense, reflux can be defined as that which goes against the flow or course of certain objects, people, or even situations. The most widespread meaning of the term, and to which it is primarily related, is that of gastroesophageal reflux: this is a condition in which, for various reasons, gastric juices, together with some of the food ingested, return to the esophagus , which is damaged by the action of the acids present in the substance. This disease represents a significant risk for those who suffer from it, since it increases the risk of esophageal cancer and causes a series of symptoms that generally affect the functioning of the body, such as difficulty swallowing, burning, internal injuries and a long-term cough. duration.

The digestive process begins when you eat food. This, first, must be converted into the food bolus, in the shape of a sphere, with the help of the teeth and the tongue; this, then, would pass through the throat or pharynx, the esophagus and, finally, it reaches the stomach. Once there, it must be broken down with the help of the acids present in the gastric juices, in order to extract all the proteins that they can contribute to the body. An important fact is that, despite the presence of acid substances in the stomach, this organ is not affected, since it produces a mucous substance on its walls that protects it; however, the area closest to it, the esophagus, does not have this property, so it is widely affected when reflux appears, its constitution being injured. This can be detected in time, resorting to esophagogastroduodenoscopy or Ph-metry.
