Hi Doctor, I have to ask about my sister, before two year she had strong fever and that was typhoid , treatment goes for long period of time near about six months, she occured problem of weight Loss and Hair Loss during that time afterwords she become well. Now in January 2011 once again She tracked with Typhoid , again she loosing hair and feel weaker also, Blood test Shows only Typhoid and Doctor gives medicines about this only and Says about Typhoid only. I have doubt about Serious Disease like Tuberculosis or else , Please suggest me some test to know the Root cause of this problem and by which test we can trace any disease if present. one more thing want to highlight she get loose motion whenever she feel fear.
