IMO, your boyfriend needs huge doses of pancreatic enzymes (wobenzym), oxygen therapies (oxygen elements plus and a water ozonator), something to get his colon cleaned out and moving ( Oxypowder , homozon, colosan, or oxycleanse) and something for his immune system (immpower). Also, it would be very beneficial if you can get him to do daily sessions on a VE-1 or a Multi-wave oscillator.
