Constant nausea for no reason 20 minutes ago no underlying conditions tho have been diagnosed with gastritis any solutions to ease the nausea ?

Lifestyle and meds: If you have gastritis, you should be on medication to block your stomach acid..Prescription or over the counter prilosec-type meds work best, but Zantac (ranitidine) can also be effective.Beyond that, you should avoid smoking, alcohol, spicy foods, licorice, peppermint, coffee, overeating or fatty meals. Eating 6 smalls meals, and nothing within 3hr of laying down, elevating the head of your bed 4-6 in can help.
