There are other tests that are helpful. A pressure recording of the esophagus is called esophageal manometry. It measures the pressure in the LES and any abnormal muscle contractions in the main part of the esophagus. Finally, a 12 to 24 hour recording of the acidity in the esophagus is often helpful. Treatment is aimed at reducing reflux and damage to the lining of the esophagus.
Initial treatment is with lifestyle changes.
Avoid eating anything within three hours before bedtime. Decrease portions of food at mealtime, and avoid tight clothing or bending over after eating. Review all medications with the physician. Certain drugs can weaken the LES, allowing acid irritation of the esophagus. Elevate the head of the bed or mattress 6 to 8 inches.
