What are the common causes of frequent abdominal bloating?

Bloating is a common digestive system issue, and the main causes of gas accumulation include:

1. Dietary factors: Excessive consumption of gas-producing foods can increase intestinal gas production; eating too quickly leads to swallowing excessive air; consuming foods or beverages containing sugar alcohols may also cause bloating.

2. Digestive problems: Conditions such as lactose intolerance and gluten-sensitive enteropathy (e.g., celiac disease) can impair proper digestion. Undigested food reaches the colon, where bacterial fermentation produces gas, leading to bloating.

3. Imbalance of gut microbiota: Disruption of the balance between beneficial and harmful bacteria in the intestine can interfere with normal digestion and absorption of food, resulting in excessive gas production and accumulation that causes bloating.

4. Functional gastrointestinal disorders: For example, irritable bowel syndrome (IBS), which is characterized by abdominal discomfort, bloating, and alternating episodes of constipation and diarrhea. The exact mechanisms are not yet fully understood but may involve abnormal intestinal motility and dysregulation of the neuroendocrine system.

If symptoms of abdominal bloating persist or worsen, it is advisable to seek medical attention promptly so that a physician can make a diagnosis and provide appropriate treatment based on the individual condition.
