Causes and Risk Factors of Acid Reflux

Gastro-esophageal reflux, commonly referred to as acid reflux, is a very common disorder, affecting more than 7 percent of the American population. Acid reflux can happen in people of all ages, although it is much more typical in newborns and young children. In contrast to kids, which are rarely confronted with lengthy-term symptoms of acid reflux, adults usually endure from recurrent types of the disorder. The process of diagnosing acid reflux is simple and it generally involves clinical examinations. Patients' reports of symptoms and physical indicators of acid reflux are usually sufficient in diagnosing the illness. However, in unique instances physicians might carry out additional tests in order to confirm presumptive clinical diagnoses.

The causes of acid reflux are numerous and of numerous natures. In most instances, chronic acid reflux disease is brought on by physiological dysfunctions, on the premises of inappropriate activity of the reduce esophageal sphincter or excessive stress inside the stomach. The lower esophageal sphincter is a ring-shaped muscular valve that usually acts as a barrier in between the esophagus and the stomach. In regular circumstances, this valve only opens during the swallowing of food, otherwise remaining closed. If the lower esophageal sphincter is weakened or its integrity is compromised (due to physical trauma), the content of the stomach can be easily regurgitated inside the esophagus and the oral cavity.

An additional common physiological cause of acid reflux is excessive pressure at the level of the abdomen, which pushes the content material of the stomach upwards, in the esophageal lining. This abnormality is more common in overweight people, smokers and pregnant women.

Many cases of acid reflux are related with hiatal hernia. Hiatal hernia generally happens when the upper wall of the stomach moves above the diaphragm. Even though this fact hasn't been confirmed, hiatal hernia is also considered to be a trigger of acid reflux. An interesting fact is that whilst most individuals with acid reflux also suffer from hiatal hernia, extremely few patients with hiatal hernia ultimately create acid reflux.

Medicines are also a cause of acid reflux disease. A wide variety of synthetic drugs can stimulate an overproduction of gastric acid inside the stomach, thus facilitating the occurrence of acid reflux. Other medications produce relaxation of the lower esophageal sphincter or decrease the pressure at the level of the esophagus.

Diet plan is also a significant cause of acid reflux. Acidic, irritant foods significantly contribute to the occurrence of acid reflux by producing an overproduction of stomach acid and by causing relaxation of the esophageal valve. Poor consuming habits (binge consuming, feasting) can also facilitate the occurrence of acid reflux. As a consequence, most symptoms of acid reflux are experienced correct after meals. Smoking and the consumption of alcohol are also recognized to be causes of acid reflux, as they interfere with the regular activity of muscular esophageal valve.
