Hi... Welcome to healthcare magic. As you mentioned you have problem of abdominal bloting problem.. I mentione following reason behind it... Food intolerance or intestinal infection may cause this type of symptoms.. Irritable bowel syndrom may ruled out.. Lactose intolerance or gluten food intolerance.. Smoking and alcohol drinking also affect.. Consult a gastroenterologist for further diagnosis.. Detail history and investigation give exact idea about problems. Abdominal x ray can done if needed... I hope my guidance helpful to you.. Take care. Thank you.
