Thanks for your question on Health Care Magic. I can understand your concern. You are having chronic typhoid infection. Actually you are mostly having chronic typhoid carrier in your gastrointestinal tract. Chronic IgM positivity suggests carrier stage. So better to get done stool culture to confirm this. You will need cephalosporin group of antibiotic for longer duration. In diet, avoid hot and spicy food. Avoid large meals, instead take frequent small meals. Avoid outside food. Eat only freshly cooked, home made food. Drink plenty of fluids orally and keep yourself hydrated. Avoid oily and heavy to digest food. Don t worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
