If esophagitis is not severe, it is okay to eat a moderate amount of sweet potatoes, as they are not highly irritating and do not significantly affect the esophagus. However, if the condition is more severe, it is necessary to control the intake of sweet potatoes. This is because sweet potatoes contain a large amount of starch, which can lead to bloating after consumption and can trigger symptoms such as indigestion. Additionally, nausea, vomiting, or acid reflux might occur. Sweet potatoes are sweet and can stimulate the excessive secretion of gastric acid, which not only causes nausea and vomiting but also affects the mucous membrane of the esophagus, potentially worsening the symptoms of esophagitis. Those with esophagitis should aim for a bland diet, eat smaller and more frequent meals, and chew slowly and thoroughly.
