“Unintentional and unconscious Partial contents of the stomach into the esophagus passes without dividing the stomach and abdominal muscles”
gastroesaofageo reflux is essentially the return of acidity in the esophagus, the long chain of 25 to 30 cm that connects the mouth to the stomach.
If the esophagus room, assisted by gravity and by a series of rhythmic movements, it is able to promote swallowed food. The passage of the bolus into the stomach is controlled by the lower esophageal sphincter, a muscular valve that opens special on the transit of food to allow “burping and vomiting. Close All sphincter prevents acidic juices rise again in the stomach,
Gastroesophageal reflux occurs when the sphincter muscle of the same name was released at the time, should not be the way to the top of the stomach contents, so (see table). Due to its the esophageal mucosa acid material is to release the cause of the typical symptoms of the disease.
This condition is pathological when it happens too often or when the reflux of stomach contents is extremely acidic.
Disease Gastroesophageal reflux disease (GERD)?
Under normal conditions, the reflux of stomach contents into the esophagus and episodic moderate amount. Only when the reflux is important determined by the frequency or severity of symptoms known as disease name of gastroesophageal reflux disease (GERD).
GERD is a mild disease but can cause chronic recurrent disorders that interfere with normal quality of life. Today we can not talk about the disease when symptoms appear (belching and retrosternal burning) at least once a week.
The most common cause of GERD is the same dysfunctional sphincter. As we have seen, when this type of valve can not correct the gastric chyme insurance irritate the work of the esophagus.
If this is the gastro esophageal sphincter, during this movement of stomach contents is pushed by gravity would be free to go up along the esophagus
The second cause in order of importance is delayed gastric emptying. When we eat foods crushing and amalgamate with saliva into the stomach, where they remain for a longer or shorter period. Over the gastric residence time of the food and the likelihood of GERD.
There may also be problems of esophageal motility; in these cases, there is a change in their ability to transport food from the pharynx to the case of the stomach.
Saliva also changes in the individual may predispose to the disease and its complications heated. Remember that saliva is slightly alkaline, which is rich in hydrogen, it is able to absorb small amounts of accidents mounted along the esophageal acid. It is no coincidence that one of the typical symptoms of reflux disease is hypersalivation, a method for the body to defend against acids.
If for any reason, the pH of the saliva is less protection is reduced and makes the esophagus vulnerable to acid attack.
With the saliva of esophageal peristalsis, helps to eliminate the physiological esophageal acid protected.
