What causes bloating and inability to pass stool?

The causes of bloating with inability to pass stool may involve several factors: 1. Constipation: Poor dietary habits and excessive intake of high-protein, high-fat foods increase the digestive burden on the gastrointestinal tract, leading to fecal impaction in the intestines. 2. Intestinal obstruction: Blockage in the intestine prevents the passage of intestinal contents, causing abdominal distension, often accompanied by cessation of flatus, nausea, and vomiting. 3. Gastrointestinal motility disorders: Insufficient gastrointestinal motility and weakened intestinal peristalsis result in delayed digestion of food and impaired gas expulsion. 4. Intestinal infection: Infections such as those caused by Shigella bacteria can damage the intestinal mucosa and cause a sensation of rectal tenesmus. 5. Intestinal tumors or polyps: These can obstruct the intestinal lumen, making it difficult to pass stool and gas. Additional contributing factors may include diet, medications, unhealthy lifestyle habits, and physiological conditions such as pregnancy. It is recommended to seek timely evaluation at a proctology or colorectal clinic when symptoms occur, to determine the underlying cause and receive appropriate treatment.
