60
Duodenal ulcers have low or high gastric acid?
high gastric acid
61
gastric ulcers have low or high gastric acid?
normal or reduced gastric acid
62
why is there a reduced amount of gastric acid with gastric ulcers?
because the cells atrophy (decrease in size)
63
risk factors for ulcers
male, first degree relatives with duodenal ulcers, stress, smoking, ASA, NSAID use
64
s/s of duodenal ulcers
food and antacids provide relief, awaken in middle of night but NOT before bkfst, melena
65
when does pain occur with duodenal ulcers?
2-3 hours after meal
66
why does food provide relief of duodenal ulcers?
because it coats the stomach
67
does food help with gastric ulcer pain?
no, it aggravates it
68
gold standard for peptic ulcer disease
culture
69
