Introduction

Gas frequently present in the intestines may be caused by improper diet. A long-term low-fiber, high-protein diet, or frequent use of antibiotics that kill beneficial intestinal bacteria, can lead to intestinal dysbiosis, resulting in persistent gas in the intestines. The exact cause of irritable bowel syndrome (IBS) is not yet clear, but it can cause discomfort such as abdominal pain and diarrhea, and contribute to the sensation of excessive gas in the intestines.

Chronic intestinal gas may result from improper diet, intestinal dysbiosis, or irritable bowel syndrome (IBS).

1. Improper Diet

Persistent intestinal gas may stem from dietary habits—for instance, frequent consumption of gas-producing foods such as onions, sweet potatoes, and white radishes, or eating too quickly, which causes excessive air to be swallowed and enter the intestines.

2. Intestinal Dysbiosis

Long-term low-fiber, high-protein diets—or frequent use of antibiotics that eliminate beneficial gut bacteria (e.g., ampicillin, clindamycin)—can alter the intestinal microenvironment, leading to dysbiosis. This condition often manifests with prominent diarrhea and contributes to persistent intestinal gas.

3. Irritable Bowel Syndrome (IBS)

The precise etiology of IBS remains unclear but is thought to involve multiple interacting factors, including gastrointestinal motility disorders and abnormal central nervous system processing of visceral sensations. Patients commonly experience abdominal pain and diarrhea, which may contribute to chronic intestinal gas.
