Severe flare up of gastritis

After an endoscopy yesterday, I was diagnosed with chronic gastritis which flares up and becomes acute. The sores and redness are visible on film. I feel terrible with pain mainly on my upper left side under ribs and in back. Also, I have pain in lower abdomen and back with diarrhea. I have a colonoscopy in several days so I supposed my colon is inflamed too. I feel nauseous every morning.
In 2011, I had these same symptoms and they ran all kinds of tests...now I realize that this is what I had because I feel the same... Since then I go through good periods, gain back the weight I lose and am able to eat most things but I flare up again every few months... This time it is pretty bad. The doctor put me back on PPIs but they don't seem to help much. The biopsies come back in a week so I will know if it is h pylori. I am looking for a natural approach to accompany the pharmaceuticals. Has anyone used cabbage juice or pine nut oil? I do take slippery elm tincture and DGL tablets..
Thanking everyone in advance for any advice. I received great support here in 2011 when I had such anxiety about this condition.

Thanks for the post Sharon,
It has been about a month and my symptoms are not going away.. None of the triggers first for me except the stress although my stress isn't terrible.i live in Louisiana and our house flooded in August with the "big flood"... We have stayed in a lovely rental and will be back in our beautiful home.
Do you think any one PPI is best? My gastro Doctor put me on 40 mg. of Prilosec.

The Prilosec is perscription...I am just so frustrated and scared...I even suffer from bile type diarrhea each time I have this...my friends tell me if it were very serious, you might not be here after suffering with this for the past 8 years...

Have you ever been checked for gallbladder or IBD? I know it seems forever, but 8 months with this type of condition is not a long time and you do have periods of time where you do feel good, so that is positive. I suffered with very similar symptoms for most of my adult life (I'm now 55). I also suffered from h. Pylori and a large HH, and eventually needed surgery. Do you take medication for anxiety?

Dear Lillye, One of the main causes of gastritis is a cork screw bacteria called H. pylori. The bacteria is present in over 70% of the population. When it enters the body, it buries itself in the thick mucus layer of the stomach and is held in check by the strong hydrochloric acid. As the strength of the acid decreases (hypochlorhydria), because of aging, antibiotics, antihistamines, proton pump inhibitors (PPIs), mucus reducing medications, etc. the bacteria starts to grow. In the process of growing it kills off the parietal cells that produce the hydrochloric acid. The reduction in the strength of the hydrochloric acid, in the stomach, allows bacterial and pathogens to dump into the small bowel resulting in gastritis and other serious conditions. Malabsorption is one of the most common conditions caused by H.pylori and low stomach acid. The cells that produce the hydrochloric acid also produce the intrinsic factor, a glycoprotein. The intrinsic factor is absolutely necessary for the absorption of vitamin B-12 in the small bowel. When the parietal cell are no longer producing the acid, they are also no longer producing the intrinsic factor, resulting in B-12 deficiency. If you were prescribed a PPI without having a pH diagnostic test, pH capsule test, or pH gastrogram, there is a high probability that you were misdiagnosed.
