Other common complaints are bloating, abdominal pain, belching, or gas. One cause is eating too much or too quickly. This may lead to swallowing air and not chewing enough. A person may also be sensitive to certain foods. Many people cannot tolerate milk or wheat products.
Emotional stress is another cause.
It often occurs while eating while nervous, upset or exhausted. Cigarettes, alcohol, and some drugs may cause it. It may also be a mild symptom of a hidden condition such as peptic ulcer, hiatal hernia, or gastritis. Antacids can often bring relief. In the long-run, however, it is wiser to identify the cause of the symptoms and make lifestyle changes.
