Yes, diet and life style changes can cause a change in the acid content of the stomach. If you are prone to it
like you have a weak esophageal sphincter or H pylori infection then diet changes can aggravate the existing
problem. Stress can add to acidity. I understand and respect your wish to not become reliant on medications.
However, though diet modification will play a huge role in reducing symptoms, it is best to take some
medication to manage the acidity and reflux. This will prevent any corrosion and ulcer formation in lining of
stomach. You could meanwhile change your diet and lifestyle.
You could make life style changes such as taking a late night snack, drinking cold milk, avoiding heavy meals
and eating frequent small meals, avoiding too much of caffeine, tea, smoking, fried food and drinks both
alcoholic and non alcoholic fuzzy ones, avoiding heavy exercises within 4 hours of a heavy meal, raising the
head end of the bed by pillows to 30 degrees, and avoiding lying down for least 2 hours after food.
Once you bring about these changes you will be able to stop the medications. However, if you were affected by
acidity once, persistent change in diet in future may cause similar problems.
Also, if your symptoms do not subside with diet and medications, then liver function test, pancreatic enzymes,
and HIDA scan for gall bladder should be done. Food intolerance and inflammatory bowel conditions such as IBS,
Crohn, celiac etc should be considered. I would suggest you consult a doctor now and start medications for
acidity and reflux. Change your diet and lifestyle and slowly taper these medications under your doctors
guidance. Please feel free to ask anything else you may want to know. Take care!
