Describe the similarities and differences in fluid and nutrient losses associated with vomiting and diarrhea


Vomiting is the expulsion of the contents of the stomach up through the esophagus to the mouth. Vomiting is often not a cause for alarm, but may cause large losses of fluid (threatening dehydration) accompanied by salts that are absolutely essential to the life of the cells. Diarrhea is the frequent passage of watery bowel movements. Like vomiting, diarrhea can lead to considerable fluid and salt losses, but the composition of the fluids is different. Stomach fluids lost in vomiting are highly acidic, whereas intestinal fluids lost in diarrhea are nearly neutral.
