I am stil having problems with gastritis, hiatal hernia went from 4 to 5, does that me it is growing? Been taking Nexium (esomeprazole) since sept 2013 and no change,

Variable. Hiatal hernias are not malignant and spread- or "grow" in that sense. They do enlarge or expand as tissue stretch. Scarring and strictures can occur so gastroenterology evaluation and egd can help clarify. Reflux treatment is important as well as elevation of head and head of bed when lying down, small meals nothing late or right before bedtime, and medication.
