You're just going to make the condition worse with alkalizing drugs. 90% of the time GERD is due to pressure in the stomach from carbon dioxide excess. Where does the CO2 come from? Bacteria! They eat carbs, turn it into CO2 and all that pressure leads to... you guessed it, reflux! They alter your body and make you not produce enough stomach acid, this is how they thrive! Acid kills them! You need MORE acid! You can mask the symptoms and worsen the condition with acid suppressing drugs, or, you can eliminate the problem entirely with Betaine-HCl supplements. The choice is yours! ;)
(Take digestive enzymes, probiotics, and magnesium too.)
Welcome to the gastroenterology community! LPR is just a type of GERD and gaviscon is one of the many medications that can be taken for gerd. Do you have any GI symptoms or have you been diagnosed with GERD?
