Can acid reflux cause a coated irritated tongue?

Yes, acid reflux can cause a coated irritated tongue. Acid reflux, also known as gastroesophageal reflux disease (GERD), is a condition in which stomach contents flow back into the esophagus. This can cause a variety of symptoms, including a coated, irritated tongue. The acid in stomach contents can irritate the tongue and cause it to become coated with a white or yellow film. The irritation can also cause the tongue to become red, swollen, and painful. In some cases, acid reflux can even cause the tongue to bleed. If you are experiencing a coated, irritated tongue along with other symptoms of acid reflux, such as heartburn, regurgitation, or difficulty swallowing, it is important to see a doctor to get a diagnosis and treatment.
