What did @anessabonner actually say?
She described taking another semaglutide injection, calling herself "stupid" for it, and then experiencing continuous vomiting since Tuesday with no food intake for multiple days. Her closing line was direct: "I don't recommend doing it. Even though you want to be skinny really bad." That's actually a more honest disclosure than most GLP-1 content on this platform. She's describing what sounds like severe gastrointestinal toxicity, not the mild nausea that pharma messaging tends to gloss over. The phrase "another shot" implies she had already reacted badly before and injected again anyway, which is the part worth unpacking clinically.
Does the science back this up?
Yes, and the data is more alarming than most creators acknowledge. Semaglutide's GI side effect profile is well-documented. A 2023 JAMA Internal Medicine study by Sodhi et al. found that GLP-1 receptor agonists were associated with significantly higher risks of pancreatitis, gastroparesis, and bowel obstruction compared to bupropion-naltrexone in patients using these drugs for weight loss. Nausea and vomiting are the most common adverse events across trials, reported in roughly 20-44% of participants in the SUSTAIN and STEP trial series. What she's describing, days of vomiting with zero food intake, sits at the more severe end of that spectrum and borders on what clinicians would flag as dehydration risk requiring evaluation. This is not just "feeling a little queasy."
- Sodhi et al., 2023, JAMA Internal Medicine: GLP-1 agonists linked to gastroparesis and other serious GI events.
- STEP 1 trial (Wilding et al., 2021, NEJM): nausea reported in 44% of semaglutide participants.
- Davies et al., 2021, Diabetes Care: vomiting rates roughly 24% in semaglutide 2.4mg group.
What did they get wrong (or right)?
She got more right than wrong. The experience she described is real, documented, and under-discussed in GLP-1 social media content. Credit where it's due: she didn't romanticize it. However, there are two problems. First, she framed this as a personal choice consequence rather than a medical safety signal. Someone vomiting continuously for multiple days after an injection should contact their prescriber or seek care, not just wait it out. That part was missing. Second, the implicit framing throughout is that the drug's purpose is to "be skinny," which strips away the clinical indication entirely. Semaglutide is FDA-approved for type 2 diabetes (Ozempic) and chronic weight management in qualifying patients (Wegovy). Using it without medical supervision, or continuing after severe adverse reactions without consulting a provider, is where the real risk lives. She called herself "stupid," but the problem isn't stupidity. It's lack of clinical oversight.
What should you actually know?
Persistent vomiting after a GLP-1 injection is not something to push through alone. Multi-day vomiting leads to dehydration and electrolyte imbalance, which can become medically serious. If you are on semaglutide or any GLP-1 and experience vomiting lasting more than 24-48 hours, that is a conversation for your prescriber, not a TikTok comment section. Dose titration exists specifically to reduce these reactions. Most protocols start patients at 0.25mg weekly for a month before increasing, precisely because jumping doses or restarting after a break dramatically increases GI severity. There is also no clinical evidence that pushing through severe side effects speeds up weight outcomes. It just increases your risk of hospitalization. A 2022 analysis in Obesity by Rubino et al. confirmed that slower titration significantly reduced discontinuation due to GI events without sacrificing efficacy. Suffering through it is not the strategy.
- Contact your prescriber if vomiting lasts beyond 24-48 hours after injection.
- Do not skip the titration phase. Lower starting doses exist for a reason.
- Dehydration from prolonged vomiting can require IV fluids and medical intervention.
- Restarting semaglutide after a break may require stepping back down in dose.
