Q: Whenever I take food from outside, within one or two months, I face the problem of typhoid. What is the solution for this? I got typhoid four times within a year and six months. I am very frustrated. Please advise. My doctor says that my immunity power is low. How can I increase my immunity?

A:Are you sure that you are suffering from recurrent typhoid? Do you have laboratory data to support this? The following should be considered if you do have recurrent typhoid. 1. The possibility of the gall bladder stones being the source of recurrent infections should be ruled out by an ultrasound. 2. Immunization is advisable. 3. Avoid eating unhygienic outside food.
