Background
Epidemiology
Epidemiologic overview
Common causes
Helicobacter pylori associated gastritis
NSAID associated gastritis
Presentation spectrum
Dyspepsia predominant
Occult bleeding possible
Coding alignment
ICD-10 gastritis codes
K29.0 acute gastritis
K29.7 gastritis unspecified
Related coding links

Pathophysiology
Mucosal defense and injury balance
Acid and pepsin exposure
Direct epithelial injury
Symptom generation via inflammation
Prostaglandin mediated defense
Mucus and bicarbonate production
Mucosal blood flow support
NSAID mechanism
COX inhibition
Reduced prostaglandins
Increased susceptibility to injury
Platelet function effects
Bleeding risk amplification
Ulcer complication risk
Helicobacter pylori mechanism
Chronic inflammation induction
Antral predominant gastritis pattern
Ulcer risk increase
Malignancy association
Atrophic gastritis progression risk
Gastric cancer risk context
Therapeutic Considerations
Acid suppression rationale
PPI mechanism
Proton pump inhibition
Enhanced mucosal healing
H2 blocker role
Acid reduction
Breakthrough symptom management
H pylori eradication rationale
Ulcer recurrence reduction
Long term benefit after cure
Reduced rebleeding risk in ulcer disease context
Need for test of cure
Persistent infection risk
Resistance driven failure risk
Guideline framing
Test and treat approach for dyspepsia in younger patients without alarm features
Noninvasive H pylori testing first
PPI trial if negative or persistent symptoms
Risk stratification for upper GI bleeding
Very low risk discharge candidates using Glasgow Blatchford score
Transfusion threshold strategy when hospitalized
Patient Discharge Instructions
copy discharge instructions
Symptom care plan
Diet and hydration
Small frequent meals
Avoid alcohol
Trigger avoidance
Avoid NSAIDs
Avoid tobacco and vaping exposure
Medication instructions
PPI or H2 blocker use as prescribed
Daily timing consistency
Do not stop early if improving
Antacid or sucralfate as needed
Separation from other medications
Constipation awareness
Return to ED now criteria
Bleeding signs
Vomiting blood
Black tarry stool
Instability signs
Fainting
New chest pain
Complication signs
Severe worsening abdominal pain
Fever
Follow up plan
Clinician follow up
Within 1 to 2 weeks if persistent symptoms
Earlier if worsening
H pylori testing or results review
Complete prescribed regimen if positive
Test of cure scheduling after therapy
