There are many different causes of nausea and belching including food poisoning, diabetic ketoacidosis, gastroenteritis, generalized anxiety disorder, panic attacks, peptic ulcers, heartburn (GERD), constipation, indigestion, overeating, mumps, swallowed objects, motion sickness, pancreatic cancer, pyloric stenosis, heat exhaustion, strokes, dyspepsia and esophagitis, according to WebMD. Knowing what the other symptoms are in addition to the belching and nausea symptoms will help doctors narrow down the diagnosis.
For patients who are experiencing an uncomfortable level of belching and nausea symptoms, it is best to visit the doctor for a diagnosis. Once the condition has been diagnosed then treatment can begin. One of the more common causes of belching and nausea is the condition known as acid reflux disease or gastroesophageal reflux disease (GERD), reports Healthline. This condition affects many people and is often caused by eating meals too closely together and over eating.
Another common condition that has high levels of belching and nausea symptoms is dyspepsia, also known as "bad digestion," reports the Gastroenterology Associates of Cleveland. With dyspepsia, the pain is felt in the upper abdomen area and there are also symptoms of bloating. To treat dyspepsia, doctors will recommend that patients eat foods that are higher in proteins or carbohydrates instead of fats and that patients avoid foods that exacerbate symptoms. There may be mediation prescribed depending on the severity of the condition.
