IBD & Cirrhosis Flashcards
2 types of IBD
crohns
ulcerative colities
symptoms of IBD
diarrhea, blood in stool, abdominal pain/cramp, weight loss, fatigue, change in daily activity
2 markers of inflammation in the bowel looked for in stool studies for iBD
lactoferrin and calprotectin
IBD confined to the rectum and colon, often starts in rectum and moves up
ulcerative colitis
depth of ulcerative colitis and nature of disease
mucosa (superficial) and continuous
UC confined to the rectum
proctitis
UC where inflammation goes up past the rectum, sigmoid colon, and descending colon up to the splenic flexure
