Welcome to HCM
After going through your history,as you are already planned for a Upper GI Endoscopy
,it would give answer to problem of pain in abdomen which according to your history may be because of APD ( Acid Peptic Disease
) that is a dudenal or gastric ulcer as pain is decreased by eating.
Gurgling sound may be because of increased motility of gut.
Once your diagnosis of APD is confirmed it can be treated accordingly, by antacids and drugs which suppress acid production it heals in 4 to 6 week time.
If required a H pylori work up may be done like a duodenal biopsy
and/or carbon urea breath test
If positive a triple therapy with antibiotics and PPI may cure and prevent relapse.
Good Luck to you
