Q

what causes PUD

A
  • when there is an imbalance between acid secretion and mucosal defense
  • helicobacter pylori infection
  • non steroidal anti inflammatory
  • cigarette smoking
  • acid hypersecretion
17
Q

which ulcers do h. pylori mainly cause

A

Duodenal ulcers- 90-95% then second gastric ulcers 70-90%

18
Q

how do PUD cause death

A

by hemorrhage ( however new studies are showing that septic shock is becoming the leading cause due to the leakage of the gastric contents)

19
