Already taking it
Most writing about these medicines is aimed at people deciding whether to start. This is for the far larger group who already have, and who keep running into things nobody warned them about.
Side effects
Is this normal?
The most-asked question by people on a GLP-1. What is expected, how long it usually lasts, and the specific things that mean stop reading and get seen.
Progress
When it slows down
Weight loss on a GLP-1 is fast, then slower, then it stops. That is what the trials show happening to almost everyone, and it is not a sign you have done something wrong.
Titration
Moving up a dose
Why these drugs are stepped up slowly, what tends to happen when you move, and why staying where you are is a legitimate option nobody offers you.
Food
Eating enough
These drugs work by removing hunger, which means the usual signal telling you to eat stops arriving. Under-eating is a real and under-discussed problem on them.
Body composition
Muscle, strength and the wasting story
You have been told these drugs strip muscle. The evidence is more favourable than that, and there is still a good reason to lift things.
Practicalities
Who needs to know you are on it
Surgery, contraception, other medicines, and the situations where not mentioning it causes an actual problem.
Supply
When you cannot get hold of it
Supply problems in this class have been constant since 2022. What to do, and the one thing not to do.
Ending treatment
Stopping
The most under-discussed fact about this entire class: appetite comes back, and usually so does the weight. What the evidence shows and what a plan looks like.
What these are and are not
No doses, no meal plans, no numbers
Same rules as the rest of the site, applied harder here because this section is read by people who are already taking something.
Nothing here contains a dose, a titration schedule, a calorie target or a gram of protein. Those depend on your body, your other medicines and your history, none of which a web page knows. Where a number would be the answer, the answer is a dietitian or a prescriber.
What is here is what tends to happen, what the evidence says about it, what the warning signs are, and what to ask the person treating you. Every guide ends by pointing at a human being, because that is where the actual answer lives.
