Final answer:
To manage GERD effectively, patients should avoid lying flat, make lifestyle changes like avoiding irritating foods, and consider elevating the head of the bed when sleeping.
Explanation:
GERD patients should avoid lying flat as it can worsen symptoms by allowing stomach acid to flow back into the esophagus more easily. Changing their lifestyle such as avoiding irritating foods, eating smaller meals, and not lying down after eating can help manage GERD effectively. Sleeping on one side may be more beneficial than lying flat, but elevating the head of the bed is a better sleep position for GERD patients.
