Does IBS Cause Nausea?
IBS is a disorder of the gastrointestinal system that is characterized by a variety of symptoms, including nausea.
A recent study found that women with IBS are more likely to have nausea than men.
The study demonstrated that, on average, men with IBS have nausea once every two weeks, while women with IBS have nausea weekly.
The length of the nausea episodes also differed. For men, nausea lasted about 30 minutes, while women had nausea for almost two hours.
Causes of Nausea in IBS
IBS is a complicated disorder, and healthcare professionals do not fully understand all of its aspects.
It’s known that there is a problem with communication between the gut and the brain, which makes the intestines more sensitive and changes how the digestive muscles move food through the system.
The digestive system also has more inflammation in people with IBS.
However, IBS doesn’t damage the intestines.
Gastroesophageal disorder (GERD) is another digestive condition that people with IBS commonly have.
It happens when acid from the stomach flows back into the esophagus and causes heartburn and other symptoms like nausea.

- Bloating.
- Abdominal pain.
- Diarrhea or constipation.
- White mucus in the school.
- Feeling like you can’t complete a bowel movement.
People with IBS can vary between having normal bowel movements and constipation or diarrhea.
Depending on what your stool pattern tends to be, your healthcare provider may diagnose you with a certain type of IBS.
IBS With Diarrhea (IBS-D)
IBS with diarrhea is when more than a quarter of your stools are loose or watery or less than a quarter of your stools are hard or lumpy on days when you have at least one abnormal bowel movement.
IBS With Constipation (IBS-C)

Identify Trigger Foods
Everyone with IBS has different foods they are sensitive to.
Identifying foods that trigger your nausea is an important strategy for managing nausea.
Consider keeping a detailed food diary to help you track your food intake and compare it to your nausea episodes.
Take notes about what foods, beverages, and supplements you take, when you consume them, andwhat symptoms you experience.
By being consistent with this, you may start to notice trends on which foods trigger nausea.
Once you know your triggers, you can avoid them and select foods that don’t trigger your nausea.
Try Low-FODMAP Diet
A low-FODMAP diet reduces foods that contain hard-to-digest carbohydrates, known as FODMAPS.
If you have IBS, your digestive tract may have trouble digesting these foods.
Consider following the low-FODMAP diet to see if your symptoms reduce.
According to the National Institute of Diabetes and Digestive and Kidney Diseases, some foods high in FODMAPs include:
- Fruits such as apples, apricots, blackberries, cherries, mango, nectarines, pears, plums, and watermelon, or juice containing any of these fruits.
- Canned fruit in natural fruit juice, or large amounts of fruit juice or dried fruit.
- Vegetables such as artichokes, asparagus, beans, cabbage, cauliflower, garlic and garlic salts, lentils, mushrooms, onions, and sugar snap or snow peas.
- Dairy products such as milk and milk products.
- Wheat and rye products.
- Honey and foods with high-fructose corn syrup.
- Products, including candy and gum, with sweeteners ending in “–ol,” such as sorbitol, mannitol, xylitol, and maltitol.
Practice Stress Management Techniques
People with IBS often have anxiety or depression.
Because IBS is a disorder of the gut-brain interaction, learning stress management techniques may help reduce your IBS symptoms.
While not specific to nausea, one study found that learning mindfulness-based stress reduction techniques helped decrease digestive symptoms related to IBS.
Other therapies medical providers often recommend for people with IBS include:
- Cognitive behavioral therapy: Learning to change your thoughts and behavior patterns may improve your IBS symptoms.
- Gut-directed hypnotherapy: Having a therapist use hypnosis to put you into a relaxed or focused state may help improve IBS symptoms.
- Relaxation training: Learning relaxation techniques can help you relax your body and reduce stress.
Take Medications
Your medical provider may prescribe medication for your IBS based on your stool symptoms.
If you tend to have diarrhea, your provider may prescribe medications to help reduce diarrhea.
On the other hand, if your stools lean towards constipation, your medical provider may prescribe fiber supplements, laxatives, and medications to help you have regular bowel movements.
If your nausea is severe, talk to your medical provider about medications specific to treating nausea.
Consult Your Medical Provider
If your nausea is not relieved by following these tips, it’s recommended you talk with your medical provider.
They can do an assessment to determine if another condition is causing your nausea.
Several conditions can cause nausea, and some of them require medical treatment.
If your nausea is severe and causes you to frequently vomit, it’s very important to stay hydrated by drinking water and fluids that contain electrolytes (fruit juices, sports drinks, Pedialyte).
Signs that you need medical care include:
- Vomiting longer than 24 hours.
- Not being able to keep fluids down for 12 hours or more.
- Vomiting three or more times in one day.
