Oats and whole grains are good sources of fiber, which is essential for heart and digestive health and aids in weight loss. However, sometimes whole grains and steel cut oats cause gas.

Fiber is an important nutrient, but it can make you feel bloated; it's as if your stomach is heavy and full of air. Unfortunately, there aren't any special high-fiber foods that don't cause gas.

Foods That Cause Gas and Bloating
Fiber helps keep your digestion running smoothly, as explained by the U.S. National Library of Medicine. It also help you to feel fuller.
However, fiber itself can't be digested. It moves into your lower intestine where it's broken down by bacteria that occurs naturally in your body, as explained by Cleveland Clinic.
When this happens, carbon dioxide and hydrogen are produced. Some will produce methane as well as a result of the fiber being broken down — a cause of oatmeal and smelly gas.
When these gases build up, you can look and feel bloated. You might have pain in your abdomen from the pressure of the gas as well.
Understand Celiac Disease
Celiac disease damages the lining of the intestines and keeps your body from being able to absorb nutrients. This is the result of a bad reaction to gluten, which is found in whole grains. You might also notice a relationship between steel cut oats and digestion problems.
Celiac disease may sound like a food allergy, but it's actually an autoimmune disorder. People often outgrow food allergies, but celiac disease is an illness that will be with you your entire life, though you can control the symptoms.
Celiac disease can make you bloated and gassy. People with celiac disease also may have diarrhea, constipation, appetite changes, nausea, vomiting, bloody, fatty or foul-smelling stools or unexplained weight loss, according to Mayo Clinic.
Since celiac disease prevents your body from absorbing nutrients, you also may experience symptoms of malnutrition if the disorder is left undiagnosed.
Symptoms include hair loss, depression, fatigue, easy bruising, missed menstrual periods, nose bleeds, muscle cramps, seizures, joint pain and itchy skin.
Seek Treatment for Celiac Disease
If you notice that you become bloated and gassy when eating certain grains — wheat, barley and rye — and oats, call your doctor if you're concerned. You should be tested for celiac disease before making any dietary changes so that the results of the testing aren't affected.
If you are diagnosed with celiac disease, you will have to eliminate certain grains, oats and all other sources of gluten from your diet, as explained by The University of Chicago Celiac Disease Center. In addition, your doctor may prescribe vitamin supplements to restore the balance of nutrients in your body.
He may prescribe a short-term round of corticosteroids if your celiac disease isn't responding to the other treatments. Once you've eliminated gluten from your diet, your intestines will begin to repair themselves and you will be able to absorb necessary nutrients again.
You must continue to follow the gluten-free diet indefinitely to avoid feeling bloated or gassy.
