Hi. Thanks for your query. Read and understood the history. You have a problem for the last 4 weeks, that you have been suffering from Vomiting of White thick foamy stuff, and pain in abdomen; can not eat anything else other than bread. Noe, vomiting stopped but it looks from your history that you are constipated and still have pain in abdomen. This can be just due to constipation, blockage of the colon by fecoliths or cancer or any other pathology like stricture and so on. I would advise you the following: Investigations first as treatment can cause more problems if the diagnosis has not been done. -X-ray of the abdomen in standing position. -CT scan of the abdomen to understand the pathology. -Once clinical evaluation is done, cleaning of the colon by enema, oral peglac like osmotic cathartic and then colonoscopy. -Barium studies if no acute obstruction -Once the diagnosis has been made, the treatment can be planned according to the findings and can be a surgery.
