For me this has been a 4 year battle & I gained what you have lost, I have bloated up & my poor stomach feels like a balloon that I just want to pop to relieve the pressure.
I suffer with pain in my chest & through to my back every day, but worst at night & worse when I'm laying down.
I no longer take any medication as after a while I was getting side effects.
When I have a bad attack, I only eat fresh juices/smoothie & soups/broths for 3 to 4 days then introduce mashed food for another 3/4 days.
Take zinc, magnesium, vitamin b complex & vitamin D as these are what your body is lacking due to the PPIs & pumps.
I'm now at the stage were my joints ache, my legs tingle, I can't sleep & feel constantly fatigued.
There is a lot of information about gastritis, you just have to continue to research. My gastritis was caused by helicobactor and even though my test came back negative, I think it's still there. As I said before I have been suffering for years & I still manage to find bits of new info on it.
Biggest hurdle is convincing the medical profession that you still feel like crap & your not improving.
Yes it's life changing, I use to be a fitness instructor & health coach & I left that industry because I was sick & fatigued.
Now I work in retail management in a stressful job, working long hours, only eating one meal a day & it is taking its toll on my health.
I know I need to make some major lifestyle adjustments, but I'm stubborn & don't like to give up what I like doing just because my health & body have let me down.
Sending you healing thoughts.

I have had gastritis for about 2 months now.... or at least thats what my doctor is telling me.
I have all the symptoms but I am so negative that i feel it has to be more.
Just like you I never had any warning, I just had a pain in the pit of my stomach with the hunger pains and constant gnawing.
My main attack stopped after I used Protonix.
It helps but I still feel a gnaw or ache in the stomach region.
I have begun to lose weight because my loss of appetite,
I dont feel hungry and when I eat I can only handle 3 or 4 bite before I am full or feeling bad.
This is taking a toll on me emotionaly and I am stressing out.
I sure hope this goes away as I am missing work, staying in bed and not spending time with my family.

I have the same conditions and losing a lot of weight also. I just try to drink banana shake in the morning and some rice and chicken which make feel little better.

I have had bad reactions to the meds and can't take them. I have had a lot of success by following the SCD diet ( specific carbohydrate diet). You have to be strict following it or you will have some bad set back days.

Hi! I was diagnosed of Acute Gastritis last June 10. For six weeks, my situation was up and down. My symptoms included nausea after every meal, gas pains especially after afternoon, combination of nausea and hyperacidity in the evening, nausea in the morning, but no pain in the abdomen. I'm guessing my gastritis was caused by too much NSAIDS and caffeine and at the night of my attack, I took and iron tablet and I read that iron tablets may trigger acute gastritis. I went to two doctors but I guess that was a mistake. The first one gave me 15 omeprazole and the second one gave me another 15 lansoprazole and 60 maalox tablets. I took the first 15 omeprazole and then continued the second set of 15 lansoprazole and 60 maalox during whick my conditions became worse. I would take one lansoprazole at night and two maalox tablets after every meal. The maalox would relieve the nausea after every meals, though. But then, I realized what could be wrong one night when I ate broccoli. (I was on a diet that time, boiled egg for breakfast, boiled veggies for lunch and broccoli for dinner) After eating broccoli, I felt terribly nauseated. But I remembered that before I had my gastritis, I had no problems with broccoli. I searched and found out that broccoli can cause indigestion. I realized taking all that ppis and antacids could have made my condition worst! Maybe my acid was not really that high. And the nausea that I felt could be my stomach wanting to expel food because it did not have enough acid to digest it. I stopped taking ppis and antacids and in two-three days my condition seemed fine but I need to be on guard from oily food and spicy food. I am planning to go on a soft diet for the next two months to completely recover. For food, I would recommend boiled egg, yogurt, thin vegetable soup, tofu and a bit of soft fish and a bit of chicken meat. No pork or beef. I hope you guys find relief! I know it's hell and you start to think life is over. I was really depressed in my six week battle. Be careful on what you eat and please do not stress yourselves.

I suffer from the gnawing hunger pains marco13 mentioned. They've basically ruined my life and won't go away. I gain weight off of about 500 calories a day. Not sure what to do. Maybe I need a different med? I'm on Zantac.
