gastritis....

gastritis is inflammation of the stomach lining....  chronic inflammation....

it occurs when you drink too much alcholol....  or....  take too many nsaids....  

infections are the most common cause of gastritis....  having too much pathogenic bacteria in the gut....  and....  helicobacter pylori is the most common cause of gastritis....  as helicobacotor pylori....  or....  h pylori....  multiplies....  it eats into the stomach tissue....  leading to gastritis....  h pylori....  also secretes an enzyme called urease....  which makes the acids in the stomach less acidic....

helicobactor pylori....  is the only bacteria known to be able to survive in the highly acidic environment of the stomach....  through local neutralization....  h pylori thrives and multiplies in a more neutral environment....  with a ph between four and eight....  so....  it neutralizes the acidity in the stomach....  making it difficult for the stomach to do its job....  killing other pathogenic bacteria....  and....  breaking down your food....  for absorption....  in the small intestine....
