This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1.
Fatigue is commonly described and hard to attribute. Substantial energy restriction produces it on its own, and separating the drug from the deficit requires a change in one and not the other.
Adding the caveat now so it does not have to be extracted later.
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.
Happy to be the one who is wrong here if it settles the question.
Coming back to post #61, because the follow-up matters more than the original answer.
Careful with the language on Fatigue. "Not detected" and "not present" are different findings and the first is a statement about the method.
Post #61 is right about the mechanism and I think understates the practical bit.
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.
Fatigue is a good example of a question where the honest answer is boring and the interesting answers are unsupported. I would go with boring.
Taking post #65 at face value and following it one step further.
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.
I read post #65 twice before replying, because I had assumed the opposite.
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.
Post #65 put the caveat in the right place and I want to underline it.
Having read the whole Fatigue thread before replying: the question in the first post has not actually been answered yet, and three of us have answered a nearby one instead.
This is the sort of exchange that makes the archive worth searching.
Pancreatitis: a rare but serious event with a specific presentation (epigastric pain, back pain, elevated lipase). If this constellation of findings appears, stopping the drug and seeking immediate evaluation is appropriate. Do not interpret this as "likely" — it is rare — but recognize the pattern if it appears.
Adding it in case it saves somebody the afternoon it cost me.
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 had written a reply contradicting post #70 and deleted it. Here is what survived.
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.
Picking up post #72: that is the part I would want checked first.
The bit of Fatigue that nobody enjoys is that the answer changes depending on what you are trying to decide with it. Say what the decision is and the thread will converge.
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.
That is the practical version. The rigorous version is longer and says the same thing.
I have three months of notes on Fatigue and the honest summary is that the trend is real and the week-to-week numbers are noise. I nearly drew the opposite conclusion from the first fortnight.
Worth separating two things that post #78 runs together.
Fatigue has a well-known answer and a correct answer, and the interesting work is establishing that they are the same. Nobody has done that here yet.
Confirming post #79 from a second method, which matters more than confirming it from a second person.
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.
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.
I am not the right person to answer the follow-up to this.
