• Causes acute episodes of non-infectious inflammation of the gut
causes of IBD
• Multifactorial causes (mainly genetic predisposition and environmental factors)
what other conditions are associated with IBD

complications of IBD
Fistula
Stricture
Abscess
where does U. colitis affect
colorectal region
common complication of U. colitis
crypt abscess
which layers of the intestines affects U/Colitis
submucosa and mucosa
where does chrons affect
mouth to anus
common area that is effected by chrons
terminal ileum and proximal colon
which condition is smoking a risk factor for and which is protective in IBD
protective in ulcerative colitis
Risk factor: crohns
which disease is worse?
which layers of the GI tract does chrons effect
all 4- mucosa, submucosa, muscularis, adventatia
systemic symptoms of IBD
Tiredness malaise
Weight loss (malabsorption)
Fever
symptoms of u. colitis compared to crohns
U.colitis has more GI and rectal symptoms
Crohns has malabsorption and mouth ulcers along with GI symptoms
both have pain

ulcerative colitis because it only effects the colon
growth failure is more common in which condition in IBD and why
crohns because cant absorb anything properly form whole GI tract

u.colitis because it only effects the colon
tenesmus is more common in which condition in IBD and why
having the feeling of needing to pass stool
u.colitis- only effects colon
endoscopic finding of IBD conditoon
u. colitis: pseudopolyps (crypt distortion)
crohns: cobblestoning: thickened wall
pattern of inflammation in IBD
u.colitis: continous inflammation with ulcers inflamed mucosa
Crohns: discontinous, ulcers innormal mucosa
medical treatment of iBD
aminosalcylates
corticosteroids
immunosuppressants
diverdiculum defintion
A diverticulum is a small, mucosa lined pouch with a narrow neck which protrudes through the colonic wall.
common site for diverticula formation
sigmoid and descending
diverticulosis
The presence of a diverticula thats asymptomatic
diverticular diease
same as diverticulosis but there are symptoms now (blood in stool)
symptom of diverticular disease
blood is stool
diverticulitis
diverticula becomes inflamed
Occurs when feces blocks neck of diverticula allowing bacteria to enter the space
who is commonly affected by diverticulosis
Commonly affects older and is characterized by left sided pain
complications of diverticulitis
Complications: • Fistula • Adhesions • Anemia (Malabsorption) • Abscesses (in pouch) • Perforation • Shock
treatment of diverticuitis
- IV Fluids
- Antibiotics
- Surgery- resect bowel
- Uncomplicated: fiber diet
presentation of diverticular
left sided pain and fever
what would make uyou think a patient has diverticula
