what can chronic gastritis lead to
Pernicious Anemia
-you need intrinsic factor from the stomach lining to absorb B12 and thus form RBCs
what is another word for Cobalamin
vitamin b12
two meds for gastritis
Ranitidine H2 blocker, Omeprazole PPI
what type of anemia do you develop from a slow bleed
iron deficiency anemia
what is GERD and what can it lead to
relfux of acid and pepsin from the stomach into the esophagus
main cause is an incompetent lower esopohageal sphincter
this can lead to esophagitis (the esophagus is not lined with protective mucosa, unlike the stomach)
and Barretts esophagus (metaplasia of the esophageal cells to a precancerous lesion) can also lead to respiratory issues
treatment of GERD
-dont lie down fro 2-3 hours after eating , maintain apropro weight, stop smoking, stress management ,
small frequent meals, drink fluids between meals but not with meals,
avoid foods that decrease LED pressure: chocolate, peppermint, tomatoes, coffee tea, avoid foods that irritate the esophagus such as tomato based
Drug therapy for GERD
decrease acid secretion: Omeprazole and H2 Blocker
neutralize gastric acid : antacid
cover and protect ulcers: Sucralfate
increase GI motility, prokinetic: Metoclopramide (Reglan)
peptic ulcer umbrella
could be in esophagus, stomach or duodenum,
duodenum is the most common
how would a gastric ulcer be different than a duodenal ulcer
gastric ulcer: anorexia and weight loss, vomiting
duodenal ulcer: pain is relieved by eating , GI bleeding might be first symptom
complications of Peptic ulcer disease
