Indigestion and increased anal gas typically indicate gastrointestinal dysfunction. In cases where these symptoms persist, it is advisable to first undergo examinations such as gastroscopy and colonoscopy to rule out any organic diseases. Once cleared, targeted treatment can be applied. For gastrointestinal dysfunction, such as Irritable Bowel Syndrome (IBS), medications that regulate gastrointestinal function like Otilonium Bromide or Pinaverium Bromide might be prescribed. Additionally, maintaining proper dietary and living habits is crucial. The diet should include light, easily digestible foods, such as soft rice or noodles, along with fresh vegetables, while avoiding greasy, spicy, and irritating foods. Although soy products are a good source of protein, they should be consumed in moderation as excessive amounts can lead to excessive gas formation in the intestines, leading to increased anal gas. (Note: Use of medications should be under the guidance of a professional doctor.)
