What should I expect?
Intragastric botox is an endoscopic injection of botulinum toxin into the stomach wall that aims to slow how quickly the stomach empties so you feel full sooner. The procedure itself is quick and has no incisions, the effect is temporary and tends to last around three to six months before wearing off, and the weight loss reported is modest with research that is genuinely mixed. It is best understood as a short window to support a diet and lifestyle plan, not a stand alone fix and not the same as weight loss surgery.
This page covers the realistic result and the aftercare that makes it count. It is general information reviewed in June 2026, not a personal treatment plan.
What the result really is.
How much, and the honest evidence. Some studies report modest average weight loss over the months after treatment, while a pooled review found no clear overall benefit compared with a control, with a possible effect only at higher doses combined with diet control. In plain terms, the evidence is mixed and any result is likely to be modest. Treat headline figures with caution and ask the doctor to be honest about what the research supports.
It is temporary. The effect tends to last roughly three to six months and then wears off as the body clears the toxin and the stomach returns to normal. People sometimes repeat it, but it is not a permanent change and not a replacement for surgery.
It only works with a plan. Any benefit depends on using the window to build smaller portions, better food choices, and more activity. Without those changes, the effect fades with the toxin. A good clinician frames it as support for a diet plan, not a result on its own.
The aftercare that makes it count.
Ease back through fluids
Many teams advise a liquid or light diet for around the first days before returning to normal food, and rest while any sedation wears off. Follow the exact advice you are given.
Use the window with a dietitian
The result depends on what you do over the next few months. Working with a dietitian or your own doctor to build lasting habits is what turns a temporary effect into a real change.
Expect mild side effects
Some people notice a sore throat, mild nausea, indigestion, or reflux for a short time. These usually settle, but ongoing or severe symptoms should be reviewed by a doctor.
Plan for it wearing off
Because the effect fades, decide in advance how you will keep up your habits afterwards rather than relying on a repeat injection as the only plan.
As an endoscopic procedure it carries the usual small risks of a gastroscopy and sedation, and rarely the toxin can spread beyond the intended area. Severe pain, persistent vomiting, fever, difficulty swallowing or breathing, or muscle weakness after treatment need urgent medical care.
The value of this treatment is in the diet support over the following months, which is hard to deliver if your team is in another country. Before you commit, work out who guides your eating plan at home and who you contact if symptoms persist once you have flown back.
Plan the support, not just the injection.
Send one brief and we route it to vetted clinics that are honest about the evidence and set out the diet support and follow up clearly. They return tailored plans and all in prices. You choose, with no pressure.
Free and no obligation. Accredited clinics only. We never sell your details.
How we make money: the guides are free and no clinic can pay to be named, ranked or recommended. We never name clinics. Get Matched is an optional service that helps keep the guides free and independent of any one clinic; using it is always your choice and you are never charged. How this works.
The things everyone asks.
How much weight will I lose?
Any result is likely to be modest, and the research is mixed, with a pooled review finding no clear overall benefit and a possible effect only at higher doses combined with diet. Be cautious of headline figures. Indicative, reviewed November 2025.
How long does it last?
The effect tends to last around three to six months and then wears off. It is temporary, so plan for how you will keep up your habits afterwards.
Is it the same as weight loss surgery?
No. It is a temporary, non surgical injection with a far smaller and less certain effect than an operation. It does not change the stomach permanently.
What are the side effects?
Usually mild, such as a sore throat, nausea, indigestion, or reflux for a short time, plus the small risks of a gastroscopy and sedation. Severe or lasting symptoms need a doctor.
