Sulphur Burps on Foundayo: What People Say Causes Them and What They Try
Burping is one of the less glamorous things to turn up in Foundayo (orforglipron) threads. The UK patient leaflet lists burping among the common side effects of the once-daily tablet, and among forum users it comes up in first-week diaries, dose-increase updates and the occasional blunt question to the whole group.
The sulphur variety, the kind that tastes and smells like rotten eggs, gets less airtime, but the people who describe it tend to do so vividly. Their accounts are personal and anecdotal, so they cannot say how often it happens or what is behind it. What follows is a look at the patterns that emerge in their own words: when it starts, what it smells and tastes like, whether it fades, and the explanations and fixes people reach for.
When the Burps Begin
For several people the burping arrives within a day or two of the first tablet. One user describes a pattern that other first-week posters will recognise: a quiet first day, then a loud second.
"I felt nothing until day 2. Burped like crazy. One week in, burped but the food noise was gone! I'm a month in- no burps. Occasionally gassy."
– cupofj47
That account has a tidy arc, but it is not the only way a start can feel. Someone worked up by reading about side effects before finally taking the first pill found the opening evening ran to a different script.
"Popped it at 7pm last night. Burps started quickly."
– Due-Rub1448
Neither account says whether the burps were of the sulphur kind, only that they came early. The distinctive smell and taste show up in other descriptions, and they are quite specific.
What It Smells and Tastes Like
The comparison people reach for is almost always eggs. A user four months into the tablet, writing a farewell update, singled out the smell of their gas as the one thing that stood apart from an otherwise quiet digestive record.
"I had no real bowel or intestinal issues but I did notice smellier gas and it didn't matter what I ate lol. It DID NOT create more gas but when I had it, it smelled pretty bad, like rotten eggs bad."
– Kekandlols
Taste and timing are tied together in another account, from someone about to start the 9 mg tablet. Their digestion is mostly quiet, but the evening meal can linger in the burps, and they have noticed a link to the clock.
"I do sometimes have gas in the mornings and can still taste my dinner in my burps if I eat after 8pm so I try to limit food intake after 8pm."

Dose Steps and Staying Power
Whether the burping settles seems to depend on who is asked. Someone who sailed through the lowest strength reports that the step up changed everything, and that the burping arrived with company.
"Didn't really have any side effects with .8 mg dosage. After a month I increased to 2.5. I am now saddled with horrible acid reflux and constant belching."
– schnoodledad1978
Another account runs the opposite way: a bad stretch of near-constant burping that eased, they say, once they reached a higher strength.
"I have some days where I am burping nonstop but it seems to have gotten better now that I’m on the 5.5mg dose."
– KnittingAlpacas
Then there are those who simply live with it. One person describes burping that they expect to stay, while the bloating that came with it eased.
"I'm also experiencing pretty consistent indigestion, mostly increased belching and bloating - eating cleaner has helped immensely with the bloating, but the belching is probably here to stay, which I'm fine with lol."

Theories and Things People Try
Online, the question of why it happens attracts confident answers. One commenter, replying to someone with a long list of digestive complaints on the lowest dose, offered a theory about sauces and slow-moving food that they presented as settled.
"I'd be willing to bet its the sauces on things.... either now not being tolerated or a combination of them upsetting your stomach. The sulphur burps are from eating foods that arent easily digestible and sitting in your stomach for a long period and basically decomposing without being excreted."
– Independent-Mine6668
It is one explanation among several, and it is a user's guess rather than an established finding. A different account of the same symptom borrows its explanation from elsewhere online, and adds a pair of changes that, they say, had pretty much cleared it by the end of week one.
"I just finished my first week. The first side effect I had was sulfur burps. From what I read it's due to the slowing of digestion. Omeprazole and avoiding fried foods has pretty much eliminated that."
– InterestingWishbone4
A third approach is to treat the burp as something that can be spotted coming. This writer, who had met the same symptom on an injection before, describes sensing one coming and reaching for an over-the-counter remedy.
"I can feel when I might be getting a sulfur burp (iykyk, Pepto is great to take when you first notice them). That is something I also experienced with Zep."
– ss0826
What Does Medino's Pharmacist Think?
"Burping is a very common part of how people describe starting a GLP-1 treatment, and the sulphur version tends to be the one they remember. What stands out in these accounts is the range: some people notice it in the first days and then it fades, some link it to a dose change, and some say it never really bothered them."
– Alessandro Grenci, Pharmacist at Medino
A Small Symptom With Many Stories
Taken together, these accounts do not point to one experience. There is the early burper whose symptom is gone within a month, the person who first met it at a higher strength, the writer who notices it only after a late dinner and the one who has simply made peace with it.
What they share is the habit of close observation: the time of the last meal, the strength of the tablet, the smell, the day of the week. Strangers compare notes in the hope of recognising their own stomach in someone else's description, and, judging from these threads, quite often they do.
