Hi thanks for your question.
along with reflux esophagitis
is common cause of the symptoms you have described.
H Pylori is common cause of gastitis and your H Pylori positive and have taken treatment for that.
You have to repeat endoscopy
or undergo urea breath test
to see whether H Pylori has been eradicated or not.
Persistent Pylori infection is responsible for gastritis
If H Pylori infection
found to be still present on repeat edoscpy or breath test, you have to repeat the treatment
I would suggest you to reconsult you physician who will be able to evaulvate you for persistent H Pylori infection .
Hope this answers your question
