Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. Typhoid can be relapsed only if proper antibiotics are not taken as pet the schedule. If the person take the antibiotics as per the schedule it will be gone forever. Bit if the schedule of the drugs are not followed it will recurr. Your current drug ceftriaxone are good and should be continued. Please take high protein and high carbohydrate diet. Avoid spicy food that can cause acidity. Please eat small frequent diet in place of single bulky diet. This will prevent perforation of intestine that can happen over the ulcer area. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
