Anti-acids don’t help because they alkalize your stomach acid , and what doctors don’t explain to us is that’s not good . Because when you stop the acid production you have more risk for gut bacterias ,you can not process food well,gut disbiosis is promoted. If you do a little of research you will find that acid reflux is not cause for high stomach acid is the opposite. It’s cause by low stomach acid and the first and main cause are because of anti acids. You have to change your diet , is key , but anti acids won’t resolve the issue at all . Besides taking Ppi , find a good quality of digestive enzymes and take them with your food , you hopefully gonna see a huge difference. Enzymes will help your stomach to digest and “cut” the food you eat . Also , you can prepare marshmallow root infusions and drink it between meals and separate from medications at least 1 hour . You can search about marshmallow root and how much it helps with this condition . It helps tons to alíviate reflux , and helps to creat a protective layer in your esophagus and stomach. I never got relief from Anti acids , they helped for some weeks and then nothing works . When I start seeing an inmunonutricion doctor everything changed. I visited different gastro doctor and nobody helped me or gave me solutions more than “you have to live with this, and also , you have to take anti-acids for the rest of your life” , and that’s not true at all. Doctors right know need to be more interesting getting more updates about certain new ways to treat some illnesses. It’s not just about what they learn 30 o 10 years ago , everything has changed and new research’s has being made . So I hope you feel better
