Hi. Thanks for your query. Noted the history and understood your concerns. Typhoid 4 years back when vomiting after taking food was the major issue which got ok after consulting the local Doctor is a good sign. Getting pressure suddenly after eating something can be due to the following reasons. An inflammatory lesion in the intestines or around it like an inflamed lymph node or so. IBS that is irritable bowel syndrome. Intolerance to something. This can be diagnosed by the following ways: Clinical examination by a General Surgeon. Ultrasonography to be followed by CT scan of abdomen. Tests of blood and stool. Colonoscopy. All these things will lead a proper diagnosis so that a proper medication can be done and get you the opinion whether this is due to a specific cause as discussed above or due to IBS that is irritable bowel syndrome wherein there i need to control the stress and anxiety and also stop the foods and beverages that are now known to instigate or enhance the problems.
