How long should I wait after eating before lying down to prevent acid reflux?

To prevent acid reflux, it's generally recommended to wait at least 2 to 3 hours after eating before lying down or going to bed. This allows sufficient time for the stomach to empty and reduces the risk of stomach acid flowing back into the esophagus.

The upright position aids digestion and helps maintain the integrity of the lower esophageal sphincter (LES), reducing the likelihood of reflux. However, individual factors such as the size and content of the meal can influence this timeframe. Consulting with a healthcare professional for personalized advice is advisable, particularly for those with persistent acid reflux symptoms.
