A weight-loss drug user revealed an unpleasant side effect of the drug that has taken a toll on her mental and physical health.
The woman, who posted on Reddit, said she was on Ozempic but did not specify how long she had used the drug or how much weight she had lost.
She wrote: ‘Since Friday, after I drank my usual protein smoothie with banana and chia seeds, I’ve been dealing with nonstop sulfur burps.
‘It’s now Monday night and still going.’
She added: ‘I’ve had short episodes like this before on Ozempic, but with diarrhea, usually lasting a couple days and then disappearing.
‘But this time it’s dragging on and it’s honestly ruined my mood. I’m worried it could be something more serious.’
Sulfur burps are burps with a strong, unpleasant odor, similar to rotten eggs, that can be caused by the buildup of gases in the digestive tract.
The FDA does list eructation, or burps, as a potential side effect of Ozempic, but says these are rare, only occurring in one percent of patients.
Clinics, on the other hand, have anecdotally reported that one in five patients on GLP-1 medications, which also include Wegovy, Mounjaro and Zepbound, experience them while on the drug.

It is one of many side effects linked to the drug, with nausea, vomiting and indigestion being the most common and experienced by up to one in five patients.
Experts say the burps are caused by the drug because it slows the passage of food through the digestive tract, causing it to ferment in the stomach for longer and release foul-smelling gases.
For those on Ozempic, reports warn that eating fat-heavy foods can raise the risk of having the burps because these foods will take even longer to exit the stomach.
Dr Karen Berger, a community pharmacist, told Very Well Health that sulfur burps are generally harmless and not a sign of an underlying condition.
She warned, however, that if burps were frequent or accompanied by other symptoms such as stomach pain or diarrhea, they could be a sign of something more serious and patients should see their doctor.
About one in eight Americans have now tried a GLP-1, and about 5million US adults were taking the drugs as of May 2025, according to a report from non-profit Fair Health.
The post on the subredit r/Ozempic by user BBW_1409 continued: ‘What’s weird is that right after I eat, the burps seem to go away or at least get masked, but then they creep back in.
‘A bit of bloating but no pain, or diarrhea this time — just the rotten-egg burps.’
Comedian and actor Stephen Fry, 66, says he lost an astonishing 70lbs in just four months after taking the weight loss drug Ozempic, but suffered chronic bouts of vomiting
She continued: ‘Since it started, I stopped eating except for rusks, rice with some grated cheese. Yesterday I thought it stopped and added some creamier chicken with the rice, and it restarted.’
Other users were quick to respond, also saying that they had experienced the burps after consuming fat-laden foods.
One said: ‘I used to get them constantly and then one day they just stopped; It was kind of shocking.’
A second said: ‘It was my enemy, found out that it happens only if I don’t consume [a] good amount of protein… and when I skip some meals’.
A third person said: ‘In most cases, [the burps are] just [a] reaction to excess fat amounts in your food. Cut fats to minimal amounts for a week and it will likely go away.’
Others said they found the burps subsided only after they cut down on red meat, onions, garlic, carbonated drinks and anything fried.
GLP-1 injections can come with more serious side effects, as well, including suicidal ideation and life-threatening intestinal blockages.
Amy Schumer is among the celebrities to reveal she lost weight after using Ozempic and then Mounjaro, but she said she had to stop because of the side effects.
The 44-year-old took Ozempic in 2023, but said in an appearance on ‘The Howard Stern Show’ in January that she quickly had to quit the drug.
She told Stern: ‘So I tried Ozempic almost three years ago, and I was like bedridden. I was vomiting. And then you have no energy.’
Weight loss drugs have taken the US by storm, with about one in eight Americans now having tried the drugs
‘I tried it and I was vomiting and I’m in bed and my son’s like, “Can you play tag?” I’m like, “I can’t.” I was shriveling.’
In a separate interview in 2023 on the Watch What Happens Live show, she said that life was not ‘livable’ for her while she was on Ozempic.
Actor and comedian Stephen Fry, 68, revealed a similar situation in March last year, saying he had also tried Ozempic for weight loss, but had to quit due to the side effects, although he did manage to lose 70lbs while on the drug.
Speaking on the River Cafe Table 4 podcast, he said: ‘I tried Ozempic years ago; I’m an early adopter of these things.
‘I happened to be in America, and I’d read about it, and I asked my doctor in America, my physician as they like to call them, and he said, “I think I can get you some”.
‘He tried me on it, and the first week or so, I was thinking, “This is astonishing. Not only do I not want to eat, I don’t want any alcohol of any kind. This is going to be brilliant”.
‘Then I started feeling sick, and I started getting sicker and sicker and sicker. I was literally throwing up four, five times a day and I thought, “I can’t do this”. So that’s it.’
