The DaVinci Orthopedic Pillow® is a patented comprehensive support system that alleviates acid reflux and GERD through proprietary positioning of the back, neck and head. For moderate to severe acid reflux symptoms, the user can easily increase the incline and effectiveness of The DaVinci Orthopedic Pillow® by putting a wedge or other pillow underneath the head part of the pillow to increase the incline up to 45 degrees.Acid reflux and GERG is not only unpleasant, it is dangerous. Not treating these conditions can lead to a number of complications, including painful swallowing and damage to the lining of the esophagus. As damage increases, the esophagus usually shrinks. This not only makes it even harder to swallow food and drinks, but also increases the probability of allowing precancerous changes in the cells to occur.Talk with your doctor before use if you have any medical conditions or concerns.
