WELCOME to HCM.
, passing out, loose motions are very late manifestations of HIV Disease. They may be the the symptoms at least 5 years after acquiring the disease after the fall of CD4 count or the immunity at a considerable level. So the present symptoms of your boy friend is very unlikely due to HIV. So your boy friend not necessarily is having HIV. Anyhow it is mandatory for him to repeat the HIV test
3 months after the last contact with you or any other sexual partner. If it is negative even after this period he need not worry any more about HIV disease.
It is always safer for anybody to have a protected sex all the time. Dr S.M
