Gastroesophageal Reflux Disease (GERD) Flashcards
Pertinent Physiology
The _________ plays a vital role in the frequency and severity of GERD
Lower Esophageal Sphincter
True/False
Some degree of reflux is physiologic. Physiologic reflux episodes typically occur postprandially, are short-lived, asymptomatic, and rarely occur during sleep.
True
Endoscopy demonstrates abnormalities in what fraction of patients?
one- third
Pathophysiology
Pain associated with GERD is secondary to the
stimulation and activation of mucosal chemoreceptors by acid.
What food exacerbate the symptoms of GERD
Spicy, acidic and salty foods
Alcohol also contribute to the onset of GERD
What issue would you suspect?
(1) Heartburn occurs 30-60 minutes after meals and upon bending over or reclining.
(2) Patients often report relief from taking antacids or baking soda.
(3) Patients may complain of regurgitation (the spontaneous reflux of sour or bitter gastric contents into the mouth).
(4) Dysphagia occurs in one-third of patients and may be due to erosive esophagitis, abnormal esophageal peristalsis, or the development of an esophageal stricture.
(5) “Atypical” or “extraesophageal” manifestations of gastroesophageal disease may occur, including:
(a) Asthma,
(b) Chronic cough,
(c) Chronic laryngitis,
(d) Sore throat,
(e) Non-cardiac chest pain
GERD
Symptoms of GERD may be similar to those of other diseases such as:
(a) Esophageal motility disorders,
(b) Peptic ulcer,
(c) Functional dyspepsia,
(d) Angina pectoris
What are some complications of GERD?
Barrett Esophagus
Peptic Stricture
What complication of GERD?
(a) This is a condition in which the squamous epithelium of the esophagus is replaced by metaplastic columnar epithelium containing goblet and columnar cells (specialized intestinal metaplasia).
(b) Present in up to 10% of patients with chronic reflux, it arises from chronic reflux induced injury to the esophageal squamous epithelium.
(c) does not provoke specific symptoms, but gastroesophageal reflux does.
(d) Most patients have a long history of reflux symptoms, such as heartburn and regurgitation.
(e) The most serious complication of this is esophageal adenocarcinoma.
It is believed that most adenocarcinomas of the esophagus and many such tumors of the gastric cardia arise from dysplastic epithelium.
Barrett Esophagus
What complication of GERD?
(a) Stricture formation occurs in about 5% of patients with esophagitis.
(b) It is manifested by the gradual development of solid food dysphagia progressive over months to years.
(c) Often there is a reduction in heartburn because the stricture acts as a barrier to reflux.
(d) Most strictures are located at the gastroesophageal junction
Peptic Stricture
LABS for GERD
None
RADS for GERD
Endoscopy- used in complicated patients
TX for GERD
Mild, intermittent symptoms
(a) Lifestyle modifications:
1) Eating smaller meals
2) Elimination of acidic foods (citrus, tomatoes, coffee, spicy foods)
3) Elimination of foods that precipitate reflux (fatty foods, chocolate, peppermint, alcohol, cigarettes).
(b) Weight loss should be recommended for overweight patients.
(c) Patients with nocturnal symptoms should be advised to avoid lying down within 3 hours after meals, the period of greatest reflux, and to elevate the head of the bed on 6-inch blocks or a foam wedge to reduce reflux and enhance esophageal clearance.
(d) Antacids
TX for GERD
Mild, intermittent symptoms
Patients with nocturnal symptoms should be advised to avoid lying down within how many hours after meals and why?
3 hours, the period of greatest reflux,
True/False
PTs lower the head of the bed with 6-inch blocks or a foam wedge at the foot to reduce reflux and enhance esophageal clearance.
FALSE
ELIVATE THE HEAD OF THE BED
