GI Stomach and Esophagus Flashcards
how does malabsorption present?
chronic diarrhea
how is malabsorption characterized?
by defective absorption of fats, fat- and water-soluble vitamins, proteins, carbohydrates, electrolytes and minerals, and water
hallmark of malabsorption
steatorrhea
steatorrhea definition
excessive fecal fat and bulky, frothy, greasy, yellow or clay-colored stools
secretory diarrhea
characterized by isotonic stool and persists during fasting
osmotic diarrhea
such as that which occurs with lactase deficiency, is due to the excessive osmotic forces exerted by unabsorbed luminal solutes. The diarrhea fluid is more than 50 mOsm more concentrated than plasma and lessens with fasting
malabsorptive diarrhea
follow generalized failure of nutrient absorption, is associated with steatorrhea, and is relieved by fasting
exudative diarrhea
due to inflammatory disease is characterized by purulent, bloody stools that continue during fasting
diarrhea definition
an increase in stool mass, frequency, or fluidity, typically greater than 200 gm per day. In severe cases stool volume can exceed 14L per day and without fluid resuscitation, results in death
dysentery definition
painful, bloody, small-volume diarrhea
malabsorption accompanying symptoms
flatus, abdominal pain, borborygmi, anorexia, weight loss, muscle wasting
