For most teenagers with GERD, the first step is lifestyle modification.

Changing your Sleeping Position: One easy thing you can do right away is elevate the head of your bed at least 6 inches. Many people put bricks or concrete blocks under one end of the bed frame. Raising your head with pillows alone is not effective enough.

Stop Smoking! Okay, you already know that smoking causes cancer and heart disease. Here is another reason not to smoke. Smoking relaxes the lower esophageal sphincter, allowing stomach acid to back up into your esophagus. Cigarette smoke also causes direct irritation in the esophagus, just like it does in the lungs.

Changing your Diet: There may be certain foods that are triggering your reflux. These foods can cause the lower esophageal sphincter to relax, allowing acid back into the esophagus. Common foods that trigger reflux include:

Caffeine (coffee and sodas)
Chocolate
Fatty and/or spicy foods

Do you really have to give up your pizza and chocolate? Maybe not. All of the foods listed above may or may not trigger your reflux. You have to determine what foods cause your reflux and change your diet accordingly. It might help to eat smaller, more frequent meals and mid-day snacks instead of just two or three big meals a day. You should avoid eating three or four hours before going to bed and if you are overweight, try to lose weight. Obesity can make it harder for the lower esophageal sphincter to close.

Avoid Alcohol
Alcohol relaxes the lower esophageal sphincter so avoid drinking beer, wine and liquor.

Review Medications
Some medications can make reflux worse, so be sure to review them with your doctor. Some medications can irritate the esophagus directly.
