Gastritis (Inflammation of gastric musoca)
Type of gastritis
Acute gastritis
often iatrogenic causes (due to medication)
Chronic gastritis
atrophy & association with increase risk of gastric carcinoma
Opportunistic gastritis
caused by infection; mostly on immunocompromised clients
Causes of gastric infections
Type A: Autoimmune Gastritis
Type B: Infections
bacterial: helicobacter pylori
Viral: Cytomegalovirus (CMV)
Clinical manifestations
asymptomatic for most clients
s/s related to peptic ulcer
dyspepsia -> show H pylori infection
Helicobactor pylori (H. pylori)
Spiral; gram-ve bacterium -> colonized human gastric mucosa
directly/ indirectly cause ulceration
Hypochlorhydria
decrease in gastric acid secretion
Urease
a enzyme product that has a protective function
within the gastric lumen
Management
medication
Triple therapy
Proton pump inhibitors (e.g. Pantoprazole - Pantoloc) + Antibiotics X2 (e.g. Amoxicillin, Clarithromycin)
Antacids
[for protecting stomach] Magnesium hydroxide (triact, mucaine)
H2 Receptor Antagonists
monitor & manage GI bleeding if present
promote optimal nutrition & fluid balance
reduce anxiety, relieving pain
Surgery
Pyloroplasty & vagotomy: longitudinal incision is made into the pylorus -> closed transversely to permit the muscle to relax; an enlarged outlet is established to enhance gastric emptying that reduced by vagotomy
Vagotomy: aims to reduce gastric acid production
Subtotal/ total gastrectomy
