While the two terms rumination and regurgitation may seem similar, they describe different processes with specific meanings. Both are involuntary processes and take place without nausea. Identifying the difference between rumination and regurgitation is essential for various fields, including veterinary science and human medicine.
The difference between rumination and regurgitation is their mechanisms. Regurgitation is the process of spitting up food from the esophagus or stomach without nausea or forceful contractions of the abdominal muscles. Rumination is the regurgitation and rechewing of the food with no apparent physical cause.

What is Rumination?
Rumination is typically observed in ruminants. In these animals, fermented ingesta or cud is regurgitated and rechewed to further break down the plant matter and stimulate digestion. There are about 200 species of ruminants, including both domestic and wild species such as mammals (cattle), all domesticated and wild bovines, goats, sheep, giraffes, deer, gazelles, and antelopes.
Moreover, rumination syndrome is a rare behavioral problem in children and some adults. This is due to voluntary muscle relaxation of the diaphragm becoming a habit. Rumination syndrome can be diagnosed through questionnaires and physical examination. Treatment involves learning how to eat and digest food properly and mastering breathing techniques.
What is Regurgitation?
Regurgitation is caused by issues within the digestive system, leading to consumed food backing up into the throat before digestion occurs. People may also experience sensations of acid moving up from the stomach into the throat or mouth. Regurgitation often stems from problems with either the upper or lower esophageal sphincter and is associated with conditions such as gastroesophageal reflux disease, overeating, eating too quickly, achalasia, pregnancy, obesity, gastritis, gastroparesis, irritable bowel syndrome, and multiple sclerosis.
Diagnosis of regurgitation typically involves a medical history review and physical examination. Treatment options for regurgitation include lifestyle modifications, dietary adjustments, over-the-counter antacids, and anti-reflux surgery.
Similarities Between Rumination and Regurgitation
- Rumination and regurgitation are two associated processes.
- The second step in the rumination process involves regurgitation.
- Both these are involuntary processes and take place without nausea.
- They can be observed in humans as well.
Comparing the Difference Between Rumination and Regurgitation
Definition
- Rumination is the process of regurgitating and rechewing food without any apparent physical cause.
- Regurgitation is the act of expelling food from the esophagus or stomach without nausea or forceful contractions of the abdominal muscles.
Caused by
- Rumination is a natural process in ruminants to aid digestion, while in children and adults, it’s often due to the learned habit of voluntary muscle relaxation of the diaphragm.
- Problems with either the upper or lower esophageal sphincter often cause regurgitation.
Seen in
- Rumination is observed in about 200 species of ruminants and in humans (children and adults).
- Regurgitation primarily occurs in humans.
Treatment
- Rumination syndrome in children and adults can be addressed through techniques for proper eating, digestion, and mastering breathing.
- Regurgitation can be managed through lifestyle changes, dietary adjustments, over-the-counter antacids, and anti-reflux surgery.
The following table presents the difference between rumination and regurgitation for a side-by-side comparison.
Summary – Rumination vs Regurgitation
Rumination and regurgitation are two associated processes. Both these processes are involuntary. However, rumination is a natural process or an eating disorder where there is chronic regurgitation of recently ingested food with subsequent re-mastication and swallowing again, whereas regurgitation is the persistent process of the spitting up of partially digested or undigested food that requires no effort. Thus, this summarizes the difference between rumination and regurgitation.
FAQ – Rumination and Regurgitation
1. What is the difference between vomiting and rumination?
- Rumination is different from vomiting. With rumination, the food is regurgitated undigested, involuntarily, and often retains its original taste. In contrast, vomiting involves the forceful ejection of the stomach and upper digestive contents through the mouth, making the expelled material unable to be eaten again.
2. What is the difference between reflux and regurgitation?
- Refux involves the backflow of stomach contents into the esophagus, often causing symptoms like heartburn. Regurgitation, on the other hand, is the passive expulsion of undigested food from the esophagus or stomach without nausea or forceful contractions of the abdominal muscles.
3. What causes people to regurgitate?
- Regurgitation is the process of spitting up food from the esophagus or stomach without nausea or forceful contractions of the abdominal muscles. Regurgitation often involves problems with either the upper or lower esophageal sphincter.
4. Is it normal to regurgitate?
- Regurgitation occurs in 80 % of people with GERD, where food, liquid, or stomach acid comes up from the stomach into the mouth. This can be treated with over-the-counter and prescription medications. However, regurgitation due to other causes should be treated differently based on the specific etiology.
5. How serious is regurgitation?
- Chronic regurgitation can decrease the quality of life. Treatment for this includes lifestyle changes, proper breathing, and drugs. For more severe cases, a surgery that involves the repairing of the lower esophageal sphincter can often reduce symptoms.
