Gerd Patho
Gastroesophageal reflux (GER) occurs when stomach acid or bile flows
into the esophagus, leading to the development of esophagitis
What are the typical symptoms of GERD?
Typical symptoms include pyrosis (heartburn) and
regurgitation/vomiting
What is pyrosis?
Pyrosis is a burning sensation or discomfort in the chest, often behind
the sternum, and is the hallmark symptom of GERD. HEARTBURN
What are some atypical symptoms of GERD?
Atypical symptoms include chronic cough, asthma exacerbations,
laryngitis, sinusitis, odynophagia, unintentional weight loss, vomiting
blood or black stools, severe chest pain, severe hoarseness, and early
satiety.
What are the risk factors for developing GERD?
Risk factors include obesity, smoking, and hiatal hernia.
What causes GERD?
,GERD can be caused by abnormalities in lower esophageal sphincter
function, esophageal motility, or gastric emptying.
How can GERD be diagnosed?
Diagnosis may involve esophageal endoscopy, impedance/pH
monitoring, and fundoplication if medical treatment fails.
What are some lifestyle modifications for treating GERD?
Lifestyle modifications include avoiding trigger foods, eating smaller
meals, stopping eating 2-3 hours before lying down, weight reduction,
smoking cessation, and elevating the head of the bed.
What is an esophageal stricture?
An esophageal stricture is the narrowing of the esophagus, which can
lead to difficulty swallowing and other related symptoms.
What are the risk factors for esophageal stricture?
Risk factors include GERD, esophagitis, ingestion of caustic substances,
and radiation therapy.
What are the symptoms of esophageal stricture?
Symptoms include difficulty swallowing, sensation of food sticking in the
throat, pain during swallowing, regurgitation of food, chest pain, choking
while eating, and unintentional weight loss.
How is esophageal stricture diagnosed?
Diagnosis can be made through a barium swallow or endoscopy.
What is appendicitis and what causes it?
Appendicitis is inflammation of the appendix, often caused by luminal
obstruction due to fecaliths, lymphoid hyperplasia, foreign bodies,
tumors, or parasites.
,What are the hallmark symptoms of appendicitis?
The hallmark symptom is abdominal pain that starts around the
umbilicus and migrates to the right lower quadrant (RLQ), along with
nausea/vomiting, loss of appetite, fever, and rebound tenderness.
What are the risk factors for appendicitis?
Risk factors include being between ages 10-19 and having a family
history of appendicitis.
What are the diagnostic tests for appendicitis?
Diagnostic tests include CBC, UA, serum HCG, CRP, and imaging studies
like CT or abdominal ultrasound.
What is a hiatal hernia?
A hiatal hernia occurs when part of the stomach pushes through the
diaphragm into the chest cavity.
What are the risk factors for developing a hiatal hernia?
Risk factors include obesity, pregnancy, and frequent heavy lifting.
What symptoms are associated with a hiatal hernia?
Symptoms include heartburn, chest pain, difficulty swallowing,
regurgitation, shortness of breath, and epigastric pain.
How is a hiatal hernia diagnosed?
Diagnosis can be made through barium swallow, chest X-ray, endoscopy,
esophageal manometry, and pH monitoring.
What are the treatment options for a hiatal hernia?
Treatment options include conservative measures, medications
(antacids, H2 blockers, PPIs), and surgical procedures like Nissen
fundoplication.
, What is Peptic Ulcer Disease?
Peptic Ulcer Disease is characterized by ulceration in the mucosal lining
of the lower esophagus, stomach, or duodenum.
What are the risk factors for Peptic Ulcer Disease?
Risk factors include H. pylori infection, NSAID use, smoking, and
excessive alcohol consumption.
What is the role of the lower esophageal sphincter in GERD?
The lower esophageal sphincter normally acts as a one-way valve to
prevent gastric contents from entering the esophagus; decreased tone
can lead to regurgitation.
What is delayed gastric emptying and how does it relate to GERD?
Delayed gastric emptying can contribute to esophagitis by extending the
period during which reflux occurs and increasing the acid content of
chyme.
What are some medications that should be avoided in GERD patients?
Medications to avoid include NSAIDs, certain sedatives or
antidepressants, and calcium channel blockers.
What bacterium weakens the protective mucus layer of the GI tract?
Helicobacter pylori (H. pylori)
What condition is caused by H. pylori colonizing the stomach lining?
Chronic inflammation and immune responses leading to peptic ulcers.
How does H. pylori infection exacerbate mucosal damage?
By stimulating increased gastric acid production.
What role do cytokines play in H. pylori infection?
