    Chronic Diarrhea And as a definition, greater than 3 weeks. Steatorrhea, this then means "steato" means lipid. For example, you've heard of Steatohepatitis or Steatosis in the liver. And that would be the accumulation of lipids. So "steato" the prefix means lipid. In this case, steatorrhea is defined as 7 grams per day of fat. That's a lot of fat that you're losing. Why? Because of malabsorption. Why? Well, maybe Gastrinoma, maybe Celiac disease, in which there is going to be destruction of the microvilli. And when such an event takes place, there'll be malabsorption. And so therefore, the stool that is being evacuated is going to be highly rich in lipid. And so therefore it is going to be extremely uncomfortable for the patient. Abdominal pain and cramps with diarrhea, chronically. Systemic symptoms such as fever, weight loss, arthritis, uveitis could be seen with chronic diarrhea. And signs of nutritional deficiencies, because over a long period of time with chronic diarrhea, you can only imagine that you're losing quite a bit of nutrients. Acute diarrhea does not require evaluation unless associated with dehydration. Stool studies, what are you looking for? Well, you might be looking for bacteria so therefore culture. Or maybe you might be looking for certain worms, ova and parasites. Remember the fish tapeworm that likes to consume B12 will be something like your <i>Diphyllobothrium latum</i>. Or if you're thinking about important nematodes and such then you might be thinking about <i>Ascaris lumbricoides</i>, <i>Trichuris trichiura</i> , <i>Strongyloides stercoralis</i>, right? So O&P. If you're in a hospital setting and the patient's receiving high doses of antibiotic, there's every possibility that you kill off all of the competitors for <i>C. diff</i>. When all the competitors are dead, <i> C. diff</i> wins his battle and may result in what's known...
