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; alpha-amylase 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 ‘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 ‘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 ‘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 Zollinger-Ellison 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 It is however recommended, when people either do not respond well to treatment or have alarming symptoms including; dysphagia, anemia, blood in the stool, wheezing, weight loss or voice changes Some physicians encourage either once in a life time, or 5 to 10 yearly endoscopy for people with long-lasting GERD to evaluate the possible presence of dysplasia or Barrett's esophagus The treatment for GERD includes; lifestyle modification medications and possibly surgery

All patients should lose weight if obese, Avoid alcohol, nicotine, spicy food, caffeine and peppermint They should also avoid eating 3-4 hours before sleeping And of course elevate their head off the bed while sleeping The primary medications used for GERD are; Proton pump inhibitors or PPI's Such as 'Omeprazole' Which is also the first-line medication Others include; H2 receptor blockers such as 'Cimetidine' And antacids For those patients who do not respond to medical therapy Surgery may be required The standard surgical treatment for severe GERD is 'fundoplication' In this procedure, The upper part of the stomach is wrapped around The lower esophageal sphincter To reenforce the sphincter and prevent acid reflux And to repair the hiatal hernia Endocinch can also be done Which, by using a scope a suture is placed around the lower esophageal sphincter to make it tighter
