Other Types
Fecal vomiting (aka stercoraceous vomiting) is a kind of vomiting, or emesis, in which partially or fully digested matter is expelled from the intestines into the stomach, by a combination of liquid and gas pressure and spasmodic contractions of the gastric muscles, and then subsequently forcefully expelled from the stomach up into the esophagus and out through the mouth and sometimes nasal passages. Though it is not usually fecal matter that is expelled, it smells noxious. Alternative medical terms for fecal vomiting are copremesis and stercoraceous vomiting. Copremesis like all emesis may lead to aspiration. However, if contents of the large intestine are aspirated, severe or even fatal aspiration pneumonia results, secondary to the massive number of bacteria normally present distal to the ileocecal valve. Projectile vomiting refers to vomiting that ejects the gastric contents with great force. It is a classic symptom of infantile hypertrophic pyloric stenosis, in which it typically follows feeding and can be so forceful that some material exits through the nose.

Famous quotes containing the word types:
“If there is nothing new on the earth, still the traveler always has a resource in the skies. They are constantly turning a new page to view. The wind sets the types on this blue ground, and the inquiring may always read a new truth there.”
—Henry David Thoreau (1817–1862)
“The wider the range of possibilities we offer children, the more intense will be their motivations and the richer their experiences. We must widen the range of topics and goals, the types of situations we offer and their degree of structure, the kinds and combinations of resources and materials, and the possible interactions with things, peers, and adults.”
—Loris Malaguzzi (1920–1994)
