Gastroesophageal Reflux Disease (GERD)
Examples of GERD
When acid from the stomach bathes the lower esophagus, a feeling of heartburn occurs. In some people, actual tissue damage occurs. This can cause some mild inflammation or reddening of the lower esophagus as seen in Image 1 or a slight erosion which has a whitish center surrounded by inflamed red tissue seen in Image 2. In the severe cases, extensive deep ulcerations occur. Images 3 and 4 show these ulcers.
