i am unclear as to what you mean by his body creating "bad bacteria" and what relationship this might have to his headaches or back problems. obviously there is much in the news about the advantages of probiotics (good bacteria) but i do not know enough about your friend to know if probiotics would help. my belief is that adding "good bacteria" will not really help his headache or back. there can be sooooo many different causes of headache and back pain that it would be in his best interest to work closely with his healthcare provider until this issue has been properly evaluated and solved.
i have a friend who's body creates more bad bacteria then good. what can we do to stop this and get more good bacteria? . she has went to several doctors but none of them know what there doing. she is always sick and always has a bad headache and back problems. please can anyone help.
