What to Expect After Botox Injection for R-CPD
R-CPD causes 4 primary symptoms: inability to belch, gurgling noises, bloating, and flatulence. Less universal symptoms include painful hiccups, nausea after large meals, shortness of breath when very bloated, hypersalivation, and constipation. For more information, see links below.
Standard of care
This is an injection of botulinum toxin (“Botox”) into the upper esophageal sphincter through the mouth during brief general anesthesia—often a “once and done” treatment.
Logistics of the procedure under general anesthesia
This will vary according to where you have the procedures done. Time required at most surgicenters will likely be 2 to 3 hours, while the procedure itself, from preop holding to O.R. to recovery room might be about 30 minutes. It is not likely strong pain medicine would be needed for most people. As for diet, most doctors will probably tell you to be guided by your throat and stomach. Key additional things to know:
- There will be no relief of R-CPD symptoms for between 1 and 5 days. Only when micro-burps begin do patients start to notice the beginning of symptom relief. So do not try carbonation for lunch on the day of the injection!
- Initial Botox side effects can be “weird” for a few days to weeks. Most are joyful due to the ability to belch and relief of bloating, but just so that nobody is surprised:
- Burping can be excessive. Some say burps happen spontaneously if they yell, clear the throat, or laugh loudly—or even breathing out after having taken a deep breath. Most say it is funny or cause for celebration. Rarely, burps can include some regurgitation, too. If present, these are expected to subside within days to weeks.
- Swallowing is peculiar initially, especially for solid foods. The limp cricopharyngeus muscle (sphincter muscle) allows food to “hang” in the throat, causing an off-putting sensation of the food remaining in your throat. If this happens, the food is in the correct place; it is in a safe place. It is not “stuck.” To manage this, always have liquid in front of you while eating. If you feel that “hanging” sensation, take a sip of water to chase the food through until this side effect soon subsides.
- Very occasionally, swallowing is more than peculiar, and the person views it as problematic. This is for maybe 1% of persons who undergo the procedure. They may consume mostly liquids and smoothies for the first few weeks to avoid the “hanging” feeling, or because food seems to push back up into the throat after swallowing. This does not mean anything bad.
- A heavy or swollen sensation in the mid-to-low neck coming from “limp muscle.” If present in initial days to weeks, some R-CPD patients feel like there is a phantom wad of phlegm or swelling in the throat. Repeated swallowing or throat clearing will not help. Instead, sip water or even try to ignore this sensation.
- Amplified or unmasked acid reflux symptoms. Where reflux symptoms increase early post-injection, the Botox injection did not cause this but rather unmasked it. Years of constant upward pressure on the lower esophageal sphincter as your body tries unsuccessfully to burp eventually damages / stretches the muscular valve at the bottom of the esophagus. This has been concealed to some degree because the acid travel upwards has been limited by trapped air and the malfunctioning / non-relaxing upper sphincter. Once burping can happen, acid can travel farther up the esophagus, accentuating heartburn, or a sour burp can now reach the mouth. This can be managed with an acid reducer medication like Prilosec OTC (omeprazole) until it subsides in a few weeks.
- Voice change: This rarely happens with O.R. injections and occasionally happens after EMG guided injection in an office setting. The explanation would be minor diffusion into laryngeal muscles.
- Noisy breathing during exertion or at night while sleeping. Again, this should be truly rare for O.R. injections.
- Laryngospasm (rare). This is extremely unlikely but can occur.
- Potential complications. The risk is extremely small. Watch Complications Compared to Expected Early Botox Effects in Treatment of R-CPD in the side bar explaining the few complications—at Bastian Voice Institute—in the first 1200 patients through January 2023.
- How do I practice burping? If you can manipulate your gurgles prior to Botox treatment, to make them softer or louder, use that technique to see if you can hurry burps along or make them bigger. Some tuck the chin, turn the head sharply to one side or the other, lower the larynx as if yawning. The trick seems to be to provide a little “help” for the burps without interfering with them. It is as though you are at the same time facilitating them and letting them happen, not “making them happen.”
- Follow-up. Each doctor will have his or her own schedule for this. An example of intervals might be 1 week, 6 weeks, 3 months, 6 months, and yearly. Things we want to know:
- Can you burp?
- Are you still gurgling?
- Is the bloating/abdominal distention gone?
- Is the flatulence diminished?
- What about hiccups, shortness of breath, hypersalivation, constipation (if you had these)?
- On a 7-point scale, what is the level of the residual problem? (Most have said it was a 6 or 7 pre-treatment.)
- Would you rate the improvement subtle, small, medium, or large? Anything else you want to say or ask.
Can’t Burp? This May Explain Why
You may have R-CPD or retrograde cricopharyngeus dysfunction. In this condition, the upper esophageal sphincter (cricopharyngeus muscle) works normally from above to permit swallowing, but it refuses to relax from below to let air be belched out.

Complications Compared to Expected Early Botox Effects in Treatment of R-CPD
In this video, Dr. Bastian distinguishes the difference between early EFFECTS that are expected, and COMPLICATIONS patients have experienced in a caseload of approximately 870 people. This informal discussion will likely reassure persons considering this treatment for the severe daily misery caused by R-CPD.
