Re: Gastritis/inflamed stomach?!
I'm not sure why she said you don't have gastritis. Gastritis means inflamed stomach, and you have that. Clear biopsies means it isn't caused by an infection or something more serious, which is good, but you still have this inflammation.
I've struggled with gastritis for years. I finally FINALLY found an answer, which is that my stomach moves too slowly.
For now, stick to as bland a diet as possible. White bread is a pretty safe bet. Potatoes (white or sweet) are a good source of nutrition. Other than apples, pears or bananas, stay away from fruit or fruit juices. Low fat, and no spices of course. Once you start to feel better, gradually introduce more foods.
Absolutely avoid alcohol, coffee, and medications such as aspirin or advil. Not necessarily forever, but for a good while after you recover.
Now, if you don't start to feel better, push for answers. I walked away from my first GI, just lived with the problem for years without seeking more treatment, and I regret that. Keep pushing, and if you don't get help, look elsewhere.
And hang in there!
