Hair shedding at month three: mechanism and time course — the long version Writing it up because I had to work it out twice and would rather nobody else did.
Reading back through what has been written here about Hair shedding, three questions come up every time and only one has ever been answered properly.
Listing all three, with what I think the state of the answer is for each, so the thread can start further along than the last one did.
The opening post is right about the mechanism and I think understates the practical bit.
Slowed gastric emptying is the mechanism behind most of the early symptoms. That also explains why eating patterns change what people experience more than almost anything else they try.
Smaller meals, less fat, slower eating and stopping earlier than feels natural are the interventions most consistently described as helping. None of them are drug interventions and all of them are about the same mechanism.
Not disagreeing with anyone above, just adding the bit I keep having to look up.
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.
It is worth stating the boring hypothesis before the interesting one.
I read the opening post twice before replying, because I had assumed the opposite.
Effects that improve with time and effects that improve with dose reduction are different findings. Working out which you have requires holding the dose steady long enough to see.
Agreed, and I will stop repeating the version of this I had been repeating.
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.
Small point, but it is the one that usually catches people.
Dehydration is the mechanism behind more of the secondary complaints here than people expect. Reduced intake plus vomiting plus a warm week is a straightforward path to feeling dreadful.
It is the sort of thing that seems obvious in retrospect and was not at the time.
Everything in post #9 holds. The case it does not cover is the one I have.
A symptom that appeared at the same time as a dose change and disappeared when the change was reversed is the strongest evidence an individual can produce, and it is still an uncontrolled observation.
Filing a mild objection to the consensus on Hair shedding. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit.
Hair shedding was covered in the wiki last year and the page has a review date on it, which is a better starting point than my memory of a thread.
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 looked this up rather than remembered it, which is the right order.
Delayed gastric emptying: the mechanism behind much of the gastrointestinal side-effect profile. At extreme magnitudes, severe gastroparesis is a rare but serious complication. Distinguishing ordinary gastrointestinal effects from the rare severe end is a clinical judgement.
That is what I would do. It may not be what is correct.
This follows post #14 rather than contradicting it.
Hair shedding some months in is described frequently here and is more consistent with rapid weight loss than with any direct drug effect. That distinction matters because it points at protein and pace rather than at the compound.
Same experience here, different supplier, so it is at least not unique to one of them.
Post #17 is right about the mechanism and I think understates the practical bit.
The version of Hair shedding that I was taught turned out to be a teaching simplification. Useful, and not true in the way I had assumed it was.
Fatigue: commonly reported, frequently multifactorial. It is worth asking whether other factors have changed (sleep, training volume, diet adequacy, hydration) before attributing all of it to the compound. Some fatigue resolves with time; some persists.
That holds under the stated conditions and I have stated them.
I had written a reply contradicting post #21 and deleted it. Here is what survived.
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.
Confirming post #21 from a second method, which matters more than confirming it from a second person.
Hair shedding: telogen effluvium associated with rapid weight loss is reported. The timing usually correlates with the speed of weight change rather than the compound specifically. It is usually self-limiting.
Happy to be the one who is wrong here if it settles the question.
Gallbladder complications: rapid weight loss increases the risk of gallstone formation. The mechanism is not specific to this drug class. The risk is greatest in the first months when weight loss is most rapid.
This follows post #25 rather than contradicting it.
Delayed gastric emptying: the mechanism behind much of the gastrointestinal side-effect profile. At extreme magnitudes, severe gastroparesis is a rare but serious complication. Distinguishing ordinary gastrointestinal effects from the rare severe end is a clinical judgement.
Coming back to post #25, because the follow-up matters more than the original answer.
I would keep Hair shedding and the decision it usually gets used for separate in this thread. They are related and they are not the same question, and merging them is why the last one went badly.
The practical version of Hair shedding is three sentences long. The rigorous version is three pages and reaches the same conclusion with the conditions attached.
That is consistent with mine, for whatever one more account is worth.
The arithmetic in post #28 is right; the assumption feeding it is the part to check.
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.
On reflection I would soften that slightly.
