I am having hypochlorhydria and experiencing symptoms like heartburn, reflux, belching? Is there any complete cure for my problem? Any natural remedy?

Heartburn. If you want to avoid unnatural remedies, first avoid any foods that aggravate your condition. Remain upright after eating/drinking. Milk may help buffer acidity. Calcium carbonate, too. If this isn't enough, you may need to break down & consider medications.
