Hello
There are many factors which may cause acidity oily foods, meal timings and gaps between the meal, less physical activity, spicy food, low water intake and others..
first of all you should increase your water intake, take more fibre rich foods like oats, whole grain, fruits and salads and cooked vegetables. Avoid spicy and oily food.
You should consult with all your details and reports because these information is not enough for proper guidance. With this information I can guide in general but to understand your specific root cause of acidity need detailed consultation.
