What is rumination syndrome?
Rumination syndrome is a rare behavioral problem. It affects children and some adults. Rumination syndrome causes an automatic regurgitation of recently eaten food. If your child has this problem, he or she will usually eat meals normally. But, after about an hour or two, undigested food comes back up into his or her mouth from the esophagus. Your child will either rechew and reswallow the food, or spit it out. Usually, this happens at every meal, day after day. Rumination is a reflex, not a conscious action.
Rumination syndrome is a rare problem. However, it may be underdiagnosed because it is mistaken for another problem.
Although still rare, rumination is being diagnosed more often in both children and adults. Experts think this may be happening because healthcare providers are now able to spot the problem. Then they can diagnose it. Rumination is not actually happening more often.
What causes rumination syndrome?
Experts think rumination is unconscious. However, they also believe that the voluntary muscle relaxation of the diaphragm becomes a learned habit. It is similar to the typical belching reflex. But rather than burping up gas, the reflex causes actual food to come back up.
What are the symptoms of rumination syndrome?
Rumination is different from throwing up. With rumination, the food is undigested and often still tastes the same as when it was first eaten.
The symptoms of rumination syndrome may look like other medical conditions or problems. Always talk with your healthcare provider for a diagnosis.
How is rumination syndrome diagnosed?
Since throwing up is much more common, rumination syndrome is often misdiagnosed as a vomiting disorder, such as delayed digestion (gastroparesis) or GERD or heartburn (gastroesophageal reflex disease).
To diagnose rumination, healthcare providers need to ask the right questions. For instance, asking what the food tastes like when it comes up is important. If it still tastes good, this means the food was not digested. This means that rumination syndrome is a good possibility. Vomited food has been digested and typically is not kept in the mouth.
The symptoms of rumination syndrome do not get better with usual treatment of reflux.
How is rumination syndrome treated?
Specific treatment for rumination syndrome will be decided by your healthcare provider based on the following:
- How old you are
- Your overall health and past health
- How sick you are
- How well you can handle specific medicines, procedures, or therapies
- How long the condition is expected to last
- Your opinion or preference
There aren’t any medicines available that effectively treat rumination syndrome. The best way to stop it is to relearn how to eat and digest food properly. This requires diaphragmatic breathing training.
A behavioral psychologist usually teaches this, and it's easy to learn. The technique has to be used at the start of every meal to avoid regurgitation. Over time, most people can master the breathing technique. This will stop the bad symptoms of rumination syndrome.
Can rumination syndrome be prevented?
Experts aren't sure why rumination syndrome starts in the first place. So it's unclear what can be done to prevent it.
Living with rumination syndrome
The good news about rumination syndrome is that it doesn't seem to do much physical damage. In rare instances, it can cause problems with the esophagus from the acid and reflux. In some teens and adults, it has caused a small amount of weight loss.
Work with your healthcare provider or your child's healthcare provider to know the symptoms. Then work with a behavioral psychologist to end the pattern.
When should I call my healthcare provider?
If your symptoms get worse or you have new symptoms, tell your healthcare provider.
