Thanks for your question.
His symptoms are more consitent with peptic ulcer disease.
gastric ulcer can cause pain with food and also decreased appetitie.
Hence, this can be called chronic gastritis.
The risk factors for gastritis are: H pylori infection, chronic NSAID use ( ibuprofen, naproxen), smoking, alcohol, hot and spicy foods, caffeine.
Liver disease also can cause chronic gastropathy or chronic gastritis.
The best test will be a upper GI endoscopy to diagnose the condition with gastric mucosal biopsy.
Blood tests consisting of complete blood count and liver function also should be checked.
The best treatment of H pylori infection will be to use triple therapy consisting of amoxicillin, clarithromysin and omeprazole for 14 days.
For chronic gastritis Omeprazole, a strong acid suppressant, should be continued for 3 months.
Alcohol, smoking, hot and spicy foods, caffeine should be avoided.
NsAID use also should be avoided.
That is all,
