What recommendation was given for her sleeping arrangements to reduce symptoms?

Elevating the head of the bed or using a wedge-shaped bolster is a commonly recommended strategy for individuals experiencing gastrointestinal symptoms such as acid reflux or GERD (gastroesophageal reflux disease). This adjustment helps to prevent stomach acid from flowing back into the esophagus during sleep, which can alleviate night-time symptoms. By elevating the upper body, gravity assists in keeping stomach contents in place, thereby reducing the discomfort associated with these conditions.

This recommendation is particularly beneficial because it addresses the underlying mechanics of how acid reflux occurs during prone or flat sleeping positions. In contrast, sleeping on a flat mattress without elevation or on the stomach may exacerbate symptoms by facilitating the return of acid to the esophagus. Similarly, while sleeping in a chair might provide some relief, it is not always practical or comfortable as a long-term solution for managing symptoms. Hence, elevating the head of the bed or using a wedge-shaped bolster is often favored for providing effective and sustainable relief.
