My brother has acute pancreatitis. Despite following a proper diet he recently us facing a lot of issues such as gas, bloating, pain, nausea etc. He is not able to eat anything and if he eats he feels nausea and sometimes vomits it out. He hasn't passes stool since 2 days despite having enough fluids. He id feeling uneasy , bloated and pain is persistent. He is pure vegetarian and neither drinks nor smokes. How can i help him feel better.
