Hi, I understand your concern. Nausea & vomiting in pregnancy can be easily controlled with- - Rest, Eating dry eatables ( bickuites, dry fruits ) very slowly , before you get up in morning. - Taking light easily digestible food small servings more frequently. -taking sips of juices/ coconut water/ soups/ cold milk . - avoid psychological stress/ have positive mentality. * medications containing Doxylamine succinate ( doxinate )at bed time help. * excessive vimiting needs Iv infusion. * Your past history of gastritis demands avoiding spicy, oily heavy to digest food . take bland food . cold milk is mostly digested well. Plain Proton pump inhibitors like Ranitidine can be taken for gastritis. Thanks.
