Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Malaise for a long time along with problems with digestion, going to toilet often, and vomiting of a brown stuff are indicative of gastroenteritis. I would advise you the following in such a situation: • Consult your doctor for clinical evaluation and examination; ask for proper investigations • Get started on a PPI like Omeprazole, Domperidone, and antacids to get the symptomatic relief If this helps, then continue with these till you are fine. If there is not much of a relief, get a second opinion of a gastroenterologist to get an upper GI endoscopy and other tests of blood and stool to get the most probable cause and get treated accordingly. Go for soft and bland diet, small frequent feeds. Avoid oily and spicy food and identify the foods and beverages that instigate or enhance the problems and stop them altogether. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. T Chandrakant
