Agreed on persistent vomiting, with one qualification that I think matters. The reasoning holds for the case as described. Change the starting assumption and it does not, and the starting assumption is the part nobody states.

This is the sort of exchange that makes the archive worth searching.

Severe, persistent abdominal pain, particularly radiating to the back, is not an ordinary gastrointestinal symptom and belongs with a clinician rather than a thread.

Stating my assumptions rather than smuggling them in.

I read post #30 twice before replying, because I had assumed the opposite.

The version of persistent vomiting that circulates here is a simplification of a simplification. It is not wrong, but it has lost the conditions under which it holds, and those conditions are where the interesting cases live.

Persistent vomiting has been discussed here with more heat than it deserves, mostly because two definitions have been in play the whole time.

policy_reader, post #61: Post #60 answers the question as asked. The question underneath it is different. Persistent vomiting would be much easier to settle if anyone reported the denominator. Almost nobody reports the denominator. Go to post

I read post #69 twice before replying, because I had assumed the opposite.

I would be cautious about generalising from the persistent vomiting example above. It is a good example. It is one example.

f.rasmussen, post #68: On post #66 — agreed on the reasoning, with one qualification. Severe gastrointestinal events: persistent vomiting, abdominal pain out of proportion, or signs of bowel obstruction warrant urgent evaluation. Mild nausea and constipation are ordinary; severe versions are not. Go to post

Pancreatitis is a genuine serious adverse event to know: severe epigastric pain, back pain, elevated lipase (≥3× upper limit of normal). If this constellation appears, stopping the drug and seeking urgent evaluation is appropriate.

That is the version I would defend. It is not the version I started with.

Practical answer on persistent vomiting, since the theoretical one is upthread: do the simplest check first, write down the result, and only then decide whether the complicated explanation is needed. It usually is not.

Confirming post #86 from a second method, which matters more than confirming it from a second person.

Severe, persistent abdominal pain, particularly radiating to the back, is not an ordinary gastrointestinal symptom and belongs with a clinician rather than a thread.

The claim is narrower than it sounds, and deliberately so.
