Since PPIs and H2 blockers haven't helped, and your symptoms specifically flare up with wheat but not rice, this suggests a couple of possibilities. It could be Eosinophilic Esophagitis (EoE)?an allergic response in the food pipe often triggered by wheat?or a specific wheat allergy or celiac disease. I highly recommend discussing these possibilities with a gastroenterologist or allergist. They may suggest an endoscopy or allergy testing to find the exact cause and help you feel much better.

To safely taper off long-term pantoprazole (Pantocid 40) and avoid rebound acidity, a gradual reduction is best. Instead of stopping abruptly, your doctor may suggest taking it every other day for two weeks, then every third day for another two weeks before stopping. If you experience mild breakthrough reflux during this transition, temporary use of over-the-counter antacids or H2 blockers can help. Lifestyle adjustments, like eating smaller meals and avoiding lying down after eating, also support this transition.

It is quite common and reassuring that this lasts only a minute. Your rapid heart rate after lunch could be triggered by a reflux-related response, where a full stomach or acid irritates the vagus nerve, temporarily speeding up your heart. Anxiety can naturally intensify this feeling. Additionally, Nicardia (nifedipine) can cause reflex heart racing, especially when blood pools in your stomach after eating. While Nixito and Pantocid-D (containing pantoprazole and domperidone) help manage your symptoms, certain ingredients can occasionally influence heart rhythm. Please share this with your doctor to review your medications and bring you peace of mind.

Since you are already taking Pantocid, a safe and gentle option you can discuss with your doctor is simethicone. This over-the-counter medicine helps break up gas bubbles in your gut and is safe to take alongside Pantocid. For additional relief, try to avoid eating heavy meals or carbonated drinks right before exercising, and consider a short, gentle walk after your evening meal to help digestion. Please consult your healthcare provider to make sure this approach is right for your daily routine.

Since Pantocid (pantoprazole) hasn't brought relief over three months, please consult your doctor about safely tapering off it, as long-term use can sometimes cause digestive changes or nutrient imbalances. Your symptoms after eating might suggest food sensitivities, stomach issues, or a mild blood pressure drop after meals. For temporary relief, try eating smaller, low-carb meals and keeping a food diary. Please see your physician soon for a thorough evaluation and blood tests to check your vitamin levels.

Since your symptoms returned immediately after stopping proton pump inhibitors, this could be due to rebound acid hypersecretion or ongoing inflammation. To guide our next steps, I recommend a simple urea breath test or stool antigen test to confirm the H. pylori infection was fully eradicated. An upper endoscopy is also a highly recommended diagnostic step to evaluate the lining of your esophagus and stomach. In the meantime, your doctor may suggest a gradual medication taper or trying an H2-receptor antagonist, like famotidine, to help manage the burning safely.
