What illness causes constipation with continuous flatulence but no bowel movement?

Constipation, frequent flatulence without bowel movements, may be caused by various factors, usually related to intestinal function and dietary habits. 1. Improper diet: Consuming excessive oily, hard-to-digest, or gas-producing foods—such as sweet potatoes and legumes—can lead to excessive gas production in the gastrointestinal tract, resulting in constipation and increased flatulence. 2. Intestinal dysbiosis: In individuals who are physically weak or suffering from certain diseases, stimuli such as diet and environment may disrupt the balance of gut microbiota, leading to symptoms including constipation, excessive flatulence, and lack of defecation. 3. Medication factors: Long-term use of certain medications, such as acarbose or sodium bicarbonate, may affect intestinal function and cause similar symptoms. Other conditions such as intestinal dysfunction or functional dyspepsia may also contribute to these symptoms. It is recommended to adjust dietary patterns, increase intake of dietary fiber, and seek medical advice when necessary, following professional guidance for appropriate treatment.
