Hi,Welcome to HCM.Gastritis
will just have abdominal pain
or burning sensation, fullness in abdomen etc, but gastroenteritis
will have vomiting
associated with loose stools with or without abdominal pain etc.Your problem looks like gastritis, so the medications prescribed to you is good and go head with it. Avoid spicy,oily and fried food.Take plenty of water.
Hope i answered your query.
