Flashcards
Diarrhoea
Flashcards do conjunto (13)
- 1What is steatorrhea, its pathophysiology and potential causes?- Pale, fatty stools which are difficult to flush
- Caused by malabsorption of fat in the small intestine --> greater
- Seen in:
○ Pancreatic insufficiency
○ Coeliac disease
○ Infection such as giardiasis - 2Several symptoms can be associated with diarrhoea. What conditions often have associated N&V?Infection, small bowel CD, small intestine bacterial overgrowth (SIBO), diabetes (causing autonomic dysfunction)
- 3Several symptoms can be associated with diarrhoea. What conditions often have associated abdominal pain?Infection, coeliac disease, IBD, malignancy, diverticulitis (sharp, constant and in LIF)
- 4Several symptoms can be associated with diarrhoea. What conditions often have associated abdominal distension/bloating?IBS, SIBO
- 5Several symptoms can be associated with diarrhoea. What conditions often have associated weight loss?Malignancy, coeliac, chronic pancreatitis, IBD, ischaemia
- 6Why might you see blood in the stools?Invasive pathogens
IBD
Malignancy
Ischaemia
Haemorrhoids/piles - 7Why might you see mucus/pus in the stools?Seen when colon becomes inflammed or infected
- 8What systemic diseases can cause diarrhoea and why?Hyperthyroidism
Adrenal disease
Diabetes
Systemic sclerosis
Various mechanisms including bacterial overload, autonomic dysfunction and contaminant drug use. - 9What surgeries may predispose someone to diarrhoea and why?Vagotomy: upper GI surgery done to reduce rate of gastric secretions (cutting one or more branches of the vagus nerve)
--> 'dumping syndrome' - rapid gastric emptying of liquids and diarrhoea
Cholecystectomy, ileal resection --> bile acid malabsorption, which stimulates secretion of fluid and colonic motility
Abdominal surgery --> SIBO due to post-op adhesions, blind loop syndrome (food doesn't follow normal digestion route and bypasses a section of intestine due to bacterial overgrowth)
Small bowel resection --> short bowel syndrome, as resulting length is not long enough to preserve fluid and electrolyte homeostasis. - 10What drugs are important to consider in a diarrhoea history?Antibiotics esp. macrolides including erythromycin, and recent therapy - risk of C diff infection with cephalosporins, clindamycin, fluoroquinolones
NSAIDs, Mg-containing products, Hypoglycaemic agents e.g. metformin, gliptins, anti-neoplastic agents - 11Is smoking a risk factor for UC or Crohn'sCrohn's - 2x risk
- 12What is the definition of diarrhoea?"The abnormal passage of ≥3 loose stools per day and/or increased stool frequency from what is normal for the individual lasting <14 days and/or stool weight >200g/day."
