Gastroesophageal Reflux Disease or GERD occurs when the acid in the stomach goes back to the esophagus- this is caused by the weakening of the Lower Esophageal Sphincter, Hiatal Hernia, abnormal esophageal contractions and the slow emptying of the stomach.
GERD is a medical condition that needs proper medical attention because it can cause numerous complications such as ulcer, fluid in the sinuses and middle ears, inflammation and infection of the lungs, cough and asthma, Barrett’s esophagus, strictures - these complications may occur one at a time or all at once. These complications can cause your life so it is really important for GERD to be treated on time. GERD can be diagnosed and evaluated through:
Endoscopy- it is a procedure where a tube that contains optical system is being swallowed. This optical system examines the gastrointestinal tract, the lining of the esophagus, stomach and the duodenum. This is the most common way in diagnosing acid reflux also known as GERD.
X-rays- GERD can be diagnosed through an X-ray of the esophagus called esophagram. This is done by swallowing the barium. The barium will then show the esophagus.
These are just few of the many ways in diagnosing acid reflux. However, you can search the internet for more information.
