what is wrong with my boyfriend

hi all. im just wondering if someone could help me. My boyfriend has been feeling severely sick all the time and he has been experiencing sever chest pain all the time.

His eating habits are terrible. he doesn't eat anything nutritious. he basically lives off pizza. 

The doctor we spoke to thought it was acid in his stomach and told him to take zantac. he has been taking these for weeks now and its not helping. 

can someone help me with any suggestions on what i can give him or what it may be

thank you  

Try Nexium 

Your boyfriend should try to change his diet to freshly cooked food and avoid anything processed.  He should try plenty fruit and vegetables to get a good intake of fibre.  If he can tolerate milk, that is also good for acid.  Avoiding anything rich, fatty or spicy is also advisable.

if you get ginger flavour tea and peppermint flavour tea and they will help and if he likes pizza try and make Cauliflower pizza and add your own topping. hope this helps
