Overview of IBS
Irritable bowel syndrome (IBS) is a chronic, or ongoing, condition that is noninflammatory. While it’s often compared with inflammatory bowel diseases (IBD) such as Crohn’s disease, IBS is different. It only affects the colon. IBS also doesn’t destroy your tissues.
Despite these key differences, IBS can still be a problem because of its symptoms. In fact, according to the , as many as 1 in 5 adults in the United States experience them. Nausea is associated with this condition. Symptoms can come and go. When they do occur, they can greatly affect quality of your life.
You can manage IBS with a combination of medical treatments and lifestyle changes, but it requires lifelong management. When it comes to nausea, it’s also important to determine whether it is a co-occurring symptom of IBS, or if it’s related to something else.
Causes of IBS Nausea
IBS doesn’t have one single cause. According to the , the main factors include:
- stronger intestinal contractions during normal digestive changes
- acute gastrointestinal disease
- abnormalities within the gastrointestinal system

Despite the variety of causes of IBS, many people are more concerned with the symptoms that often disrupt their quality of life. There’s no single cause of IBS-related nausea, but it’s indeed prevalent among patients. According to , medical doctor and professor at UCLA, one of her 2014 studies found that IBS-related nausea affects about 38 percent of women and 27 percent of men. Hormonal changes are an issue for women who have IBS, and IBS affects mostly women, according to the .
Nausea in people who have IBS is often related to other common symptoms like fullness, abdominal pain, and bloating after eating. While not always the case, IBS nausea can occur most often after certain foods trigger your symptoms.
Certain medications, such as the IBS drug lubiprostone, can also increase your risk of nausea. Other non-IBS drugs you may take from can also cause nausea:
- non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen
- birth control pills
While nausea can occur with IBS, your doctor may consider other causes if you don’t exhibit any common IBS symptoms. Furthermore, your nausea can be related to other conditions you might have, such as:
- gastroesophageal reflux disease (GERD)
- occasional heartburn

- abdominal pain
Nausea itself is most commonly caused by viral gastroenteritis. Therefore, if you only experience nausea temporarily, it may be part of an illness other than IBS.
Conventional Medical Treatment
Prescription medications solely intended for IBS include alosetron and lubiprostone. Alosetron helps to regulate your colon’s contractions and slows down digestion. Alosetron is only recommended for women who have tried other medications that have failed.
Lubiprostone works by secreting fluids in IBS patients experiencing chronic constipation. It’s also only recommended for women, but one of the side effects is nausea.
Sometimes IBS treatments will not help alleviate all related symptoms. In other words, it may be helpful to directly treat some of the most prevalent problems. With persistent nausea, you might consider antinausea medications like prochlorperazine.

While IBS itself doesn’t lead to more serious complications, nausea can become problematic.
Malnourishment, for instance, is just one concern. Avoiding symptoms like nausea can discourage you from eating a wide range of foods that would otherwise be a part of a balanced diet. Also, if your nausea is accompanied by vomiting, you might not get enough nutrients.
