Cough
Bile is an acidic substance that can inflame the delicate lining of the digestive tract. Patients who develop gastritis as a result of chronic bile reflux can experience frequent throat irritation due to this condition. Consequently, patients with this condition may develop occasional episodes of coughing that may be accompanied by a raspy or hoarse voice.

Heartburn
Gastritis caused by chronic bile reflux can lead to frequent symptoms of heartburn in affected patients, health officials at the University of Maryland Medical Center in Baltimore note. Symptoms of heartburn typically include a sensation of burning within the upper stomach, chest or throat. Patients with gastritis may notice that heartburn symptoms are worse after eating or during the night.

Abdominal Pain
Bile is a fluid produced by the liver that aids in the digestive process within the small intestine. Gastritis can occur when this acidic substance abnormally flows backwards from the small intestine into the stomach and esophagus--a condition known as bile reflux. High levels of acid within the stomach due to bile reflux can cause severe irritation and inflammation leading to sensations of pain within the abdomen, doctors at the Mayo Clinic explain. The intensity of abdominal pain can vary from mild to severe depending upon the frequency and duration of bile reflux episodes.

Nausea or Vomiting
Bile within the stomach due to bile reflux can cause significant irritation, which can lead to symptoms of nausea or vomiting in patients with gastritis. These symptoms can be uncomfortable and may contribute to a loss of appetite in certain patients. Vomit that contains blood or resembles coffee grounds can be indicative of severe intestinal or stomach damage.
