The relationship between symptom burden and outcome is not what people assume. Feeling worse is not evidence of a larger effect and feeling nothing is not evidence of an inactive preparation.
Posting this under the heading it deserves: Constipation management, with a dietitian's contribution Everything below is what sits behind that.
Constipation management: setting out the arithmetic in full, because I have had to do it twice and I would rather nobody else did.
Every step is shown. If the answer is wrong the error will be visible, which is the point of writing it out rather than posting the result.
That is a fair summary of where the discussion has got to.
What I can speak to on constipation management is narrow, so I will keep it narrow rather than generalising from it. Beyond that boundary I do not know.
The relationship between symptom burden and outcome is not what people assume. Feeling worse is not evidence of a larger effect and feeling nothing is not evidence of an inactive preparation.
One more thing on constipation management that took me far too long to see: the two figures people quote are not measuring the same quantity. Once you notice that, the apparent contradiction disappears.
The failure mode on constipation management is boring rather than dramatic. It is almost always the step everyone assumes was done correctly because it is too simple to get wrong.
Clear enough that I do not think I have a follow-up, which is unusual.
The published rates come from populations that were titrated on a defined schedule with clinical supervision. Rates from a forum are not comparable and are biased by who chooses to post.
I have kept the units in throughout, for the obvious reason.
Recognition and grading: nausea ranges from "noticeable" to "limiting". Constipation ranges from mild to severe. Having language to describe the magnitude helps you track whether something is worsening or stable and helps your clinician understand what you are reporting.
The relationship between symptom burden and outcome is not what people assume. Feeling worse is not evidence of a larger effect and feeling nothing is not evidence of an inactive preparation.
I would put the burden of proof on the interesting explanation, not the dull one.
Worth separating two things that post #9 runs together.
Reframing constipation management slightly, because I think the disagreement is about the question rather than the answer. If the question is "does it happen", yes. If it is "how often", nobody here knows.
Post #13 is right about the mechanism and I think understates the practical bit.
Something worth flagging about constipation management: the strongest-sounding claims in this thread are the ones with no source attached, which is the usual pattern and not a coincidence.

I checked the source rather than the summary, and they differ.
Where the constipation management discussion usually stalls is that nobody wants to say "I do not know" and everyone is willing to say "it varies". Those are the same sentence with different clothes on.
Same experience here, different supplier, so it is at least not unique to one of them.
Offering a way to settle constipation management rather than another opinion about it. Two measurements, taken the same way, a fortnight apart. If the difference is within the noise, the question was not answerable at this precision.
This follows post #18 rather than contradicting it.

I am not the right person to answer the follow-up to this.

Constipation management looks different depending on whether you are reading the primary literature or the summaries of it, and the difference is not in our favour.
I read post #20 twice before replying, because I had assumed the opposite.
Small methodological point on constipation management: repeating a measurement is cheap and resolves most of what is being argued about here at no cost to anyone.
Following this. I have the same question and no better information than the first post.
The published rates come from populations that were titrated on a defined schedule with clinical supervision. Rates from a forum are not comparable and are biased by who chooses to post.
The mechanism is plausible, which is not the same as established.
Picking up post #22: that is the part I would want checked first.
Two questions I would want answered before drawing anything from the constipation management data above: how were the cases selected, and what happened to the ones that dropped out.
On constipation management the community has more anecdote than the confidence in this thread implies, and I include my own contribution in that.
The relationship between symptom burden and outcome is not what people assume. Feeling worse is not evidence of a larger effect and feeling nothing is not evidence of an inactive preparation.
Worth reading the earlier posts in this thread before acting on mine.
Helpful, and easy to find again, which is half of what a good reply is.
Seconded. It reads as careful rather than confident, which is the right register.

The reasoning is more useful than the number, which is why I have shown it.
