My fiance had stomach cramps and profuse vomiting that smells like feces, and he says looks and tastes the same. he doesn't have ins. what can we do?

Go to emergency room: Any time there is concern for feces in the vomitus, a small bowel obstruction needs to be ruled out. An abdominal x-ray is required. Rehydration and medication for nausea is also available.

Not a good sign: Generally, vomit that is feculant (smells like stool), is indicative of a distal bowel obstruction. You must take him to the hospital where further testing will be done to rule this in or out. Seriously.
