It does not always follow that the ways of preventing acid reflux includes the penetration of the affected inner regions such as the stomach and the esophagus.
Efforts made by the patient him/herself must be observed too, for there are ways by which proper physical activity can prevent the said condition from occurring.
Here are some simple ways:

• Reserve some time for exercise.
  Jogging every morning and doing some sweat-producing routines are not only good for the whole body, but could also help you lose a little weight.
  These activities can lessen the chances of acid reflux since the fats in the body which also store acids decrease along with the problem itself.
  
• Good sleeping habits.
  Many people who experience acid reflux say that the ailment usually occurs at night time or can be evidenced by the bitter taste in their mouths when they wake up in the morning.
  To prevent this, it is prescribed to sleep with pillows piled up under the head so that the acids would not reach the patient's mouth in the morning and will continuously flow down back to the stomach.
  It is also suggested that the patient wear larger sizes of clothing so that the pressure to the body, especially to the abdominal region, will lessen.
  This will enable better flow of body fluids.
  

Preventing acid reflux can be done in simple ways, but it is also important to do these things correctly.
It is important to make these habits for them to become effective.
