Diarrhea
-
Caused by infections, toxins, food, drugs, Anxiety
-
-
-
-
Stool Osmotic Gap
Stool is usually isotonic, when Na/K are lower than normal, due to the extra volume, hence stool osmotic gap will be larger
Osmotic Vs Secretory
Fasting
Osmotic Diarrhea will resolve with fasting, but secretory will not
-
-
Control of Absorption
Factors: Paracrine, Endocrine, Nervous influences
-
Opioids nad somatostin (ileum, and colon) stimulate water and electrolyre absorption
-
Inhibition of absorption by inflmmatory mediators (Histamine, Proglandins)
Sodium
Sodium transport occurs throughout length of small intestine (via passive diffusion + special mechanism)
-
-
Colon
Absorbs water and electrolytes from chyme, produces thick mucinous secretion
