GERD Gastroesophageal reflux disease Heartburn MADE EASY
Digestion begins in the mouth, as food is broken down by chewing into smaller pieces. And by saliva releasing digestive enzymes such as; alphaamylase and lingual lipase When food is swallowed, it enters the esophagus A muscular tube, that carries food from the mouth to the stomach for further digestion. Contractions called â€˜peristalsis’ push the food down the esophagus. At the bottom of the esophagus food passes through a muscular valve Called the ‘Lower Esophageal Sphincter’ or ‘LES’ and into the stomach. The digestive juices secreted by the stomach are highly acidic.
When the stomach contracts to move the food into the intestine, The â€˜LES’ closes tightly in order to prevent these acidic juices From moving back into the esophagus where they can cause damage. A breathing muscle called the ‘diaphragm’ separates the chest from the abdomen. To reach the stomach the esophagus passes through the diaphragm, At a point called the â€˜hiatal ring’. If the patient has gastroesophageal reflux disease or GERD, Their LES does not close properly allowing acidic stomach contents,.
To flow backward into the esophagus. If GERD is not treated it can lead to variety of esophageal problems Including; ulcers, bleeding, stricter and narrowings And Barrett’s esophagus, in which the normal Stratified squamous epithelium lining of the esophagus, Is replaced by simple columnar epithelium Which are usually found lower in the GI tract. If the patient has hiatal hernia.
A portion of their stomach Is protruding into their chest cavity Through the opening in their diaphragm. A Hiatal hernia can effect the LES And increase the risk and severity of GERD. Some of the factors that can contribute to GERD are; Hiatal hernia, as we have already mentioned, Obesity.
ZollingerEllison syndrome, which can present with Increase gastric acidity, due to increase ‘gastrin’ production, Hypercalcemia, which can also increase gastrin production Leading to increase acidity. Scleroderma and Systemic sclerosis, which can feature esophageal dysmotility. Signs and symptoms of GERD includes; Epigastric burning pain traveling up into the chest.
Known as ‘heartburn’ Which can sometimes spread to the throat Along with a sour metallic taste in the mouth. Difficulty swallowing Dry cough Sore throat Hoarseness Which is due to the acid damaging the larynx or the voice box.
Regurgitation of food or sour liquids And, a sensation of a lump in the throat. GERD is most often diagnosed based on the patient’s history and symptoms. In some patients in whom the diagnosis is not clear 24 hour pH monitoring is done to confirm the etiology Endoscopy is not routinely needed, if the case is typical and responds to treatment.
