A burning sensation in the chest or throat
A burning sensation in the throat or chest that feels worse with swallowing may be a sign that stomach contents are being refluxed up into the esophagus. This pain can last from a few minutes to hours.
Sour or bitter taste in the mouth
A sour or bitter taste can occur when stomach contents reflux up into the esophagus.
A sore, raw throat, especially upon waking in the mornings
At night, more acid is produced by the stomach and a person is lying down, which makes it much easier for the acid to flow up to the top of the esophagus and throat. This can result in a sore throat in the morning.
Irritation caused by refluxed stomach acid into the throat can lead to hoarseness.
Trouble swallowing and/or a feeling like food is stuck in the throat
Trouble with swallowing (dysphagia) occurs when food does not pass normally from the mouth through the esophagus to the stomach. There may be a sensation of food sticking in the throat, chest pressure or "burning" after eating, or a feeling of choking. Difficulty swallowing could be a sign of various conditions, including erosive esophagitis, and should always be evaluated by a physician.
Respiratory problems (such as bronchitis, wheezing, asthma)
Several studies suggest a significant link between GERD and asthma. GERD can affect asthma when refluxed acid from the stomach is aspirated into the lungs, and can make breathing difficult and cause the teenager to wheeze and cough.
Nagging dry cough
A frequent dry cough may occur if refluxed stomach acid is aspirated, which can irritate the airways; refluxed stomach acid itself also can irritate the throat.
