What Causes Gas-Bloat Syndrome?
Gas is a natural part of the digestive process in your body, and it’s also natural that burping and passing gas takes care of any excesses. Sometimes, gas may be blocked, not moving well through the digestive system, causing feelings of bloating, pain, and swelling.
Occasional problems with these symptoms occurring together are also natural and normal. When the issue is chronic and frequent, you may have gas-bloat syndrome.
Visit us at Gastroenterology & Nutrition of Central Florida when these symptoms occur frequently or are accompanied by other gastrointestinal symptoms. We’ll diagnose and treat the underlying causes of your condition.
What causes gas?
Gas in your digestive system stems from two general sources. Swallowing air usually causes belching as the air gets released from the stomach back up through the esophagus. Surgery for gastroesophageal reflux disease (GERD) can cause gas bloating since it prevents the return of stomach contents in this direction.
Causes of air swallowing include:
- Fast eating or drinking
- Drinking through a straw
- Chewing gum
- Loose dentures
- Smoking
The second source of digestive system gas starts with the breakdown of food that isn’t absorbed or digested in the small intestine. Usually, this is due to foods containing carbohydrates.
Soluble fiber, which dissolves readily in water, is a common source of gas. When reaching the large intestine, gut bacteria break down undigested fiber, starch, and sugar, forming carbon dioxide, hydrogen, and methane.
Proteins and fats produce little gas, as does insoluble fiber, the food component of certain whole grains like wheat and some vegetables that provide healthy bulk to your stool. All gases produced in the intestines are normally eliminated through the rectum.
What causes bloating?
Any interruption to the regular routes of eliminating gas from the digestive system can cause bloating, which may also result from an overproduction of gas. Some causes of bloating include:
- Bacterial overgrowth in the small intestine: resulting from large intestine bacteria back flowing into the small intestine, changing the normal balance
- Digestive disorders: including irritable bowel syndrome (IBS) and functional dyspepsia
- Problems with carbohydrate absorption: carbs from beans, wheat, fructose, and lactose, sometimes due to intolerance or other dietary sensitivity
- Contents of the digestive system: such as constipation, bowel obstruction, weight gain, or disorders with the way waste moves through the colon
- Hormone conditions: though primarily a bloating symptom in women, it can include passing gas as a symptom, too
- Visceral sensitivity: sometimes you may feel bloated or gassy even when the volume of gas is normal
