You can test your saliva or urine pH at home using over-the-counter pH test strips, though these do not measure your internal blood pH, which your body naturally keeps in a safe, healthy range. If you are experiencing symptoms of high stomach acidity, simple lifestyle changes like avoiding trigger foods can help. For quick relief, generic antacids containing calcium carbonate or magnesium hydroxide can neutralise stomach acid. To reduce acid production, generic H2 blockers like famotidine or proton pump inhibitors like omeprazole are highly effective. Please consult a doctor to determine the best treatment plan for your specific needs.
