Hi, Gas and heartburn after bowel resection surgery could indicate various issues, including: * Adhesion-related complications: Adhesions are bands of scar tissue that can form after abdominal surgery, causing organs or tissues to stick together. Adhesions can sometimes lead to bowel obstructions or partial blockages, resulting in symptoms such as gas, bloating, and difficulty passing stool. * Gastroesophageal reflux disease (GERD): This condition causes the stomach acids to flow back into the esophagus. This regurgitative response leads to heartburn among other symptoms. While it is more commonly associated with a weakened lower esophageal sphincter, it s possible that changes in the anatomy of the digestive system after bowel resection surgery may contribute to the development or worsening of GERD. * Other digestive issues: Bowel resection surgery can alter the normal functioning of the digestive system, potentially leading to issues such as impaired digestion, altered bowel movements, and changes in the gut microbiota. These changes can result in symptoms like gas, bloating, and discomfort. * Other factors: It s also worth considering other factors that could contribute to your symptoms, such as dietary choices, medication side effects, stress, or other underlying health conditions. Given your history of abdominal surgeries and the current symptoms you re experiencing, it is important to consult with a healthcare professional. They can evaluate your specific situation, perform any necessary tests or imaging studies, and provide a proper diagnosis and appropriate treatment plan. They may refer you to a gastroenterologist or a surgeon with expertise in abdominal adhesions if needed. Take care. Hope I have answered your question.
