Peptic Ulcer
Stomch
it's break in the normal tissue that lines the stomach
if ulcer is in stomach ==== Gastric ulcer
if ulcer is in doudenum ==== Dudenal ulcer
stoumach + duodenal ulcer
:::Causes:::
In past: It was belived that life style factors such as
stress and diet caused ulcer
يعني نوعية الأكل والضغط النفسي والتوتر مش مسبب للقرحة لكن مجرد عامل مساعد أ, بس بيزود الألم مش أكتر
أمال ايه السبب؟؟ 
later: Researcher determined that stomach acids and pepsin are controling the peptic ulcer
يعني في عدم توازن بين الأحماض الي بطلعها المعدة (كتير) وبين الطبقة المبطنة للمعدة (ضعيفة أو قليلة)
Today: 80% of gastric ulcer and 90 % of duodenal ulcer are devlop due to infection by bacterium called
Helicobacter Pylori
طلعت في الآخر بكتيريا 
ايه نظامها البكتيريا دي بقى..؟؟...
This H.Pylori is the cause in about 19 in 20 cases
This bacterium affects the lining of the duodenum in some way which allows the acid to cause inflammation and ulcers
Researchers are not certain how people contract H. pylori, but they think it may be through food or water
Researchers have found H. pylori in the saliva of some infected people, so the bacteria may also spread through mouth-to-mouth contact such as kissing
:::Risk factor for Gastric Ulcer:::
use asprin and (NSAIDs) ie. Non Stroidal Anti
Infilamatory Drugs ex:Ibuprofen
These medicines sometimes affect the lining of the
duodenum and allow acid to cause an ulcer
H.Pylori: Which weaken the stomach's protective mucus and make it more susceptible to damage by acid and pepsin as well as produce more acid
Smoking
Alcohol
Caffeine
Stress
